1803–1818

*1803: A similar event occurred in 1803, when it was decided that the military affairs of the Province of Guayaquil (whose capital was the strategically situated port city of

) would be run from Lima. * 1810: all administrative and economic affairs of the province were turned over to the Viceroyalty of Peru, a state of affairs that would endure until 1819. Jaén de Bracamoros had no such cedula transferring it to Peru and would rightly belong to Ecuador. However, Jaén decided to join Peru after it took part in northern Peru's revolutionary wars of independence. * September 28, 1812: the Council of Regency requested from Madrid the ''Expediente sobre la erección del Obispado de Maynas y las Cédulas que se expedieron en 1805 acerca de los limites'' ("File on the erection of the Diocese of Maynas and the Decrees that were issued in 1805 regarding the borders"). With no response forthcoming, a Decree of the Courts rendered the Decree of 1802 null and void on November 13, 1812. * September 13, 1813: the ''Real Cédula de 1813'' was issued to replace the 1802 decree, in its first article ordering "''entregar al Ordinario las nuevas Reducciones y Doctrinas que tuviesen mas de 10 años de antiguedad, proveyéndose en eclesiásticos seculares, conforme a las Leyes del Patronato. ''" * September 26, 1813: the Bishop of Maynas, Friar Hipólito Sánchez Rangel, notifies the Overseas Minister that "''solo assisten los Religiosos de Quito en Maynas y dice es fuerza, pues, si se tratan de hacer justicia que se me ponga en otro Obispado que sea menos penoso.''" * May 1, 1814: the census carried out by Sanchez Rangel reads: in 58 towns of the 90 that make up said diocese there are no more than eight assistant priests, three of which are located at the extremes of the Bishopric: three in small rivers, one in the dilated course of the great rivers Guallaga and Marañón, and none in the Napo, Putumayo, Ucayale and Pastaza. This mean that 60 villages were without a parish and almost all the missions were abandoned. Sanchez Rangel had written in 1813: "''Desde que salieron los jesuitas de estas tierras no ha habido quien se contraiga a su fomento espiritual ni temporal; todos se han buscado a sí mismos. De esta proposición que es absoluta y de una eterna verdad se ha seguido naturalmente lo que estamos viendo y tocando con dolor, que ya no ha quedado cosa alguna de lo que aquellos padres establecieron y solo hay lo que produce la madre naturaleza.''" * September 27, 1814: Sanchez Rangle requests that the Bishopric of Maynas be suppressed, its erection null and void due to a lack of compliance with the ''Real Cédula de 1802''. * February 22, 1815: The Council of the Indies receives a letter from Sanchez Rangel dated January 28, 1814. Bishop Rangel proves that the Decree of 1802 has not been met by the government, the priests at the edges of the Bishopric, nor the "P.P. de Ocopa". *February 7, 1815: The President of Quito, Toribio Montes reports regarding the Missions of Maynas, saying "''He manifesto a V.E. en informes anteriores, que las Missiones del Marañón se hallan en un sensible atraso, faltándoles el número completamente Ministros evangélicos...Incluye a Maynas en los dominios de Quito''" *1816: The King of Spain issues a Royal Order revoking and annulling the ''Real Cédula de 1802''; on September 22, the President of Quito receives the files related to the revocation. *1818: The President of Quito names Don Juan Navas Governor of Quijos. On June 19, the Council of the Indies tells the story of the creation of the Bishopric and the General Command of Maynas, the lack of compliance with the Decree of 1802, and the impossibility of compliance with the former. *July 22, 1818: The President of Quito asks the Viceroy of Peru for the revocation and annulment of the ''Real Cédula de 1802''. On August 23, the Viceroy acknowledges the Royal Order of 1816, returning the province of Maynas to Quito.

'' principle as the basis for the territorial demarcation of the new nation-states that were to be born out of the ancient colonial jurisdictions. In essence, the principle stated that the borders of the new countries should correspond to the Spanish administrative borders, as they were in 1809. By this principle, the territory of the ''Viceroyalty of Peru'' would become the Republic of Peru (modern Peru), and the territory of the ''Viceroyalty of New Granada'' would become the Republic of Colombia (Greater Colombia, which included modern Colombia, Venezuela, Ecuador, and Panama). Border disputes arose when Peru began basing its borders on the Cedula Real of 1802 which gave them rights to claim territory in the Amazon region and the Cédula of 1803 which gave Peru the right to claim Guayaquil and the coast of Ecuador. Colombia claims that both Cedulas are do not change political borders because the Cedula of 1802 refers only to Ecclesiastical borders and the 1803 cedula deals with mercantile and military jurisdictions. Gran Colombia basis its borders on the unmodified Cédula of 1740 to define its borders with Peru. * July 6, 1822: Monteagudo-Mosquera Treaty :Mosquera's mission to Lima had two objectives: (1) To come up with a treaty of alliance between Gran Colombia and Peru against Spain, and (2) To have Peru recognize that

Gran Colombia–Peru conflict

, who had been a member of Bolivar's troops during the wars of independence and born in Cuenca, Ecuador, had his own political ambition. De La Mar wanted to establish himself as the formal ruler of Peru which in precolonial times was called Inca Empire which included Peru, Ecuador, and Bolivia. Because of De La Mars ambition of restoring the glory of the Inca Empire by annexing Ecuador and Bolivia to Peru, relations between Bolivar and De la Mar quickly boiled over and the two soon became rivals. Deciding to free Peru (what is now Peru and Bolivia) from what he considered to be an authoritarian project, De la Mar promoted an anti-Bolivarian campaign which gained popular support and led to insurrections, both in Peru and in Bolivia (Alto Perú), where the Colombian Army was expelled. Finally, he decided to confront Bolivar more directly by launching an attack. On June 3, 1828, de la Mar invaded the southern region of Gran Colombia; he occupied Loja and tried to capture Guayas, and intended to annex those territories to Peru. Furious upon hearing the news, Simón Bolívar resolved to declare war against Peru. Sucre was appointed Commander of the Colombian Army. In 1829, De la Mar and General Agustin Gamarra occupied Cuenca, but were defeated in what is known as the Battle of Portete de Tarqui (also known as the
Battle of Tarqui The Battle of Tarqui, also known as the Battle of Portete de Tarqui, took place on 27 February 1829 at Tarqui, near Cuenca, today part of Ecuador. It was fought between troops from Gran Colombia, commanded by Antonio José de Sucre, and Peruvian ...

Subsequently, the ''Convenio de Girón'' between Peru and Gran Colombia recognizes as borders the "same ones of the corresponding Viceroyalties before independence." On July 10, the Piura Armistice recognised the annexation of

* February 28, 1829: La Mar-Sucre Convention :This convention was signed the day after the Battle of Tarqui was won by Gran Colombia ending Peru's attempt to forcefully annex the Department of Guayaquil and the Department of Azuay from the Gran Colombia. * September 22, 1829: Larrea-Gual Treaty :Ecuador considers this a transitional treaty that resulted from the Battle of Tarqui and later developed into the disputed Pedemonte-Mosquera Protocol the next year. The ''uti possidetis'' principle was ratified, allowing for small concessions with the end of coming up with a more natural and precise border so as to avoid further conflict. The parties agreed to form a binational commission to establish a permanent border

The Gran Colombia federation dissolved during 1830 because of political struggles between regions which strengthened after Bolivar's resignation. Ecuador was born as a country on May 13, 1830, and began its separate existence with the adoption of a Constitution on September 23, 1830. According to this constitution, the

Confusion about Gran Colombia

The term Gran Colombia is used today to refer to the federation that was formed between the Republics of Ecuador, Colombia (with Panama) and Venezuela before 1830. However, ''Gran Colombia'' is an anachronistic term, as the country was simply referred to as ''Colombia'', which is clear, for example, by looking at original documentation of the many treaties signed between ''Colombia'' and Peru before 1830. In Peru, the dissolution of Gran Colombia is seen as a country ceasing to exist, giving way to the formation of new nation states that had nothing to do with the original federation. The significant implication of this view is that the treaties Peru had signed with Gran Colombia were voided, as the country in question no longer existed, and was replaced with three new states, the
Republic of New Granada The Republic of New Granada was a 1831–1858 centralist unitary republic consisting primarily of present-day Colombia and Panama with smaller portions of today's Costa Rica, Ecuador, Venezuela, Peru and Brazil. On 9 May 1834, the national flag wa ...
(which subsequently changed its name to Republic of Colombia), the Republic of Venezuela and the Republic of Ecuador. An alternative view is that Ecuador and Venezuela separated from the Gran Colombia Federation (from Colombia in actuality) and inherited any treaties that Gran Colombia had signed with Peru as they applied to their corresponding territories. There are indications that Colombia itself maintained this position. On the surface, it seems far-fetched that the Republic of Colombia after 1830 is a different country from the Republic of Colombia before 1830, even though they shared a capital city, a subset of territory and much of their citizenry. Additionally, the argument that border treaties are voided when federations are dissolved does not appear to have substantial merit and is clearly conflict-prone.


The Pedemonte-Mosquera Protocol

Ecuador and Colombia maintain that the Pedemonte-Mosquera Protocol was signed in

the new boundary. However, it left the status of a small area in the Andes Mountains named Jaén de Bracamoros in dispute. It was decided by Pedemonte and Mosquera that on a later date, either the Chinchipe River or the Huancabamba River would be chosen as the new boundary. Ecuador has used this protocol as primary legal support of its core claims throughout the history of the conflict. Peru has disputed the credibility and the existence of the Piedemonte-Mosquera protocol on several points: * The original document has not been produced either by Colombia or Ecuador. * Piedemonte and Mosquera were believed to be at different locations on the day in question. * The protocol was never ratified by either country's congress. * Even if the protocol took place, Ecuador had separated from the Gran Colombia Federation a month before the signing of the protocol – August 11, 1830. * The copy produced by Colombia is not sufficient evidence for Peru. Even though it seems unlikely that Ecuador would have concocted a historical treaty of this nature, the fact that the existence of the original document cannot be demonstrated conclusively is significant. Ecuador has managed to produce a copy made in 1870 that the Colombian embassy in Lima sent to
Bogotá Bogotá (, also , , ), officially Bogotá, Distrito Capital, abbreviated Bogotá, D.C., and formerly known as Santa Fe de Bogotá (; ) during the Spanish period and between 1991 and 2000, is the capital city of Colombia, and one of the larges ...
. The copy in question was obtained from someone's personal collection. However, it was not certified by Peru and remains disputed. The Piedemonte-Mosquera protocol is mentioned in a Colombian document titled Legislative Act No. 3 published October 31, 1910

The document explains how the borders between Colombia and its neighbors have been established; as to its border with Peru, it indicates they are ''those adopted by Mosquera-Piedemonte, in development of the treaty of September 22, 1829.''

Treaties with Brazil and Colombia (1832–1856)

*February 10, 1832: The Separation of Ecuador from Gran Colombia legally recognized :The Republic of Nueva Granada (Colombia) recognizes separation of the Departments of Quito, Guayaquil, and Azuay from the Gran Colombia union to form the New nation of Ecuador which declared its separation May 12, 1830. * July 12, 1832: Pando-Noboa Treaty :Peru recognizes Ecuador as a new republic and signs a treaty of friendship, alliance and commerce. Article XIV mentions that until a convention, respecting the limits of the 2 states, shall have been concluded, the present limits shall be recognized and respected. * 1841–1842 Period: León-Valdivieso and Daste-Charún negotiations :In 1841 Ecuador demands return of the jurisdictions of Tumbes, Peru, Tumbes, Jaén and Maynas. After violent discussions, Ecuador gives an ultimatum to the effect that if there's no answer from Peru by a certain date, Ecuador would be forced to occupy territories considered Ecuadorian according to article 5 of the Larrea-Gual treaty of 1829

Peru considered it absurd to return provinces that were de facto, if not in fact, Peruvian. Recall that Peru considered Maynas annexed to the

Additionally, inhabitants of Jaén and Tumbes had freely indicated their desire to belong to Peru (free determination), even though there was no Royal Decree (Real Cédula) from the King of Spain substantiating their claim. Moreover, Ecuador's claim to Tumbes and Jaén is solely from the Cedula of 1563 and Cedula of 1740 unmodified in the eastern regions of Ecuador

Territorial negotiations failed in 1842 as the Ecuadorian envoy insisted on the return of Jaén and Maynas. * October 23, 1851: Peru-Brazil Treaty :Peru fixes its eastern border with Brazil; however, Ecuador and Colombia protested that the border fixed with Brazil north of the Amazon called the Apoparis-Tabatinga line is within disputed Amazon Territories. The disputed territories (triangular in shape) at that time was disputed between Ecuador, Colombia and Peru and covered everything east of the Andes mountains and everything in between the Caquetá-Japurá river and Marañón-Amazon river. * March 10, 1853: Creation of the Peruvian Government of Loreto :To justify its claims to the disputed amazonian territory Peru decides to create a separate amazonian political military government naming it the Government of Loreto, after Peru successfully takes over a small amazonian port called Nauta. The policy of the Loreto Government is to concentrate on exploring, taking over, and settling these vacant areas with Peruvian citizens before Ecuador and Colombia, thus having a good de facto position if the dispute goes to arbitration. Before 1890, the fluvial armada concentrated in taking over the small river ports along the Marañón river like Nauta, Omaguas, Iquitos, Regis, Parinari, Antonio, Santander, Barrabca, Borja, Mazan, and Destacamento. Most of the exploration of the tributary rivers north of the Marañón river was conducted by a Peruvian military commander named Coronel Pedro Portillo in the early 20th century. The Peruvian fluvial armada at that time consisted of lightly armed rafts and boats with its main base in Iquitos, the capital of Loreto. In this way most of the northern tributary rivers which drained into the Marañón – Amazon river and its adjacent disputed territories were occupied by Peruvians.


Ecuadorian–Peruvian War (1857–1860)

This was an expensive war fought over disputed territory bordering the Amazon. On September 21, 1857, Ecuador decided to adjudicate to Britain territories in the ''Canelos'' region as payment for international debt it had incurred during the war of independence. Peru immediately protested the Ecuadorian action citing the ''uti possidetis juris'' principle by which the ''Canelos'' region would belong to Peru, based on the territorial concession of 1802 to the ''Viceroyalty of Peru''. Despite Peruvian complaints, Ecuador proceeded in its negotiations with the British. This led to an 1859 occupation and blockade of

by President Castilla. (Ecuador at the time was undergoing a civil struggle.) On February 25, 1860, Peruvian minister Manuel Morales and his Ecuadorian counterpart, Nicolás Estrada, signed the ''Treaty of Mapasingue'' in order to end the dispute. (Mapasingue is a location near Guayaquil where Peruvian troops had been stationed.) Ecuador voided the concession of territories claimed by Peru to the British, and Peru withdrew its forces. However, the territorial situation remained unclear and was left to be resolved at a later time.


Boundary negotiations and treaties (1860–1941)

* 1864: Peruvian Navy establishes presence in Iquitos :Steamships of the Peruvian Navy arrived at Iquitos, first the ''Morona'' and ''Pastaza'' of 500 and 300 tons, and then two smaller steamboats of 50 tons, the ''Napo'' and the ''Putumayo''. Shortly afterwards a dockyard and a navy factory arrive from England and are installed, thus establishing the ''Factoria Naval de Iquitos''. * August 1, 1887: Espinoza-Bonifaz Convention :In the Espinoza-Bonifaz convention Ecuador and Peru submitted their dispute to arbitration by the King of Spain. Ecuador announced its withdrawal from the process months before a decision was issued, which was expected to be in 1910. Ecuador alleged that the King was not impartial because the officially undisclosed decision was not favorable. Additionally, there were popular protests in Ecuador against Peru. The King subsequently abstained from issuing a decision. Arbitration documents confirmed Peru's right to Maynas and other lands in dispute

Ecuador's position was that arbitration did not arrive at a satisfactory conclusion because even Peru's representative had expressed that the King did not have the capacity to consolidate peace, as both countries were parting from absolutely opposing principles

* May 2, 1890: Herrera-García Treaty :Because of the many disagreements during the arbitration by the King of Spain, Ecuador and Peru decided to enter direct negotiations. This was in part accepted by Peru due to the recent Peru-Chile (1879–1883) war, which resulted in its defeat and loss of territory to Chile. The treaty signed by Pablo Herrera and Arturo García gave, dominion and access to the Amazon river, the Napo River, Napo and Putumayo rivers, and control over parts of the provinces of Tumbes and Maynas, and the ''Canelos'

This treaty was quickly ratified by Ecuador's congress. Since the Peruvian Congress thought the treaty unfavourable, they ratified it in October 1891, provided they were allowed to introduce modifications, which reduced Ecuadorian sovereignty over the Marañón – Amazon rivers. Ecuador's congress subsequently disapproved the Herrera-García treaty due to the modifications introduced by Peru. Ecuador also requested meetings to further discuss its validity thesis on the Guayaquil (Gual-Larrea) Treaty of 1829

* May 6, 1904: Tobar – Rio Branco Treaty between Brazil and Ecuador :In 1904 Ecuador decides to sign a treaty of friendship, alliance, and free navigation with Brazil. With this treaty Ecuador relinquishes its ancient Spanish colonial rights to present-day Brazilian territory that exactly covers an area between the Caqueta and Amazon rivers. * July 15, 1916: Muñoz-Suarez Treaty between Colombia and Ecuador :This treaty put an end to a long border dispute, that arose after Ecuador's separation from the Gran Colombia on May 13, 1830. Under the terms of the treaty, the new boundary was a somewhat straight imaginary line that started in the Pacific Ocean and ended in the Amazon River. In the Andes region the boundary followed the present borders between Ecuador and Colombia. Then starting around 75°W Longitude the border followed a somewhat straight line midway between the Putumayo and Napo rivers until it reaches the Ampiyacu River, which was picked as a natural border in jungle region between Ecuador and Colombia. The border then followed the Ambiyacu River and ended when it reached 72°W Longitude on the Amazon River. With this treaty Ecuador gave up a portion of its ancient colonial claims to a territory that reached north to the Caqueta River and east to the Brazilian border. * June 21, 1924: Ponce-Castro Oyangurin Protocol :This is a protocol signed between Ecuador and Peru, wherein both parties agreed to send their representatives to Washington so that they could try to resolve their border disputes in an amicable manner through a direct negotiation compromise method followed by a partial arbitration by the President of the United States. The meetings commenced September 30, 1935, and lasted two years. From the start the President of the United States was asked not to interfere with the direct negotiations by the Peruvian delegation, since his duty would be to arbitrate a final solution based on these direct negotiations if said negotiations failed. During that time period neither party seemed to agree on defining the boundaries of the disputed area to arbitrate by the President of the United States. In essence, Ecuador considered all of Tumbez, Jaén, and Maynas to be Ecuadorian because of its numerous de jure colonial titles, but was willing to divide them up through a compromise negotiation method for the sake of peace. In contrast, Peru considered Tumbez, Jaén, and Maynas to be all Peruvian because of their de facto occupation and the real cedula of 1802 title, and showed up in Washington to only negotiate what the borders of these provinces were in relation to Ecuador. Because of the failure to agree on what lands were disputed, the conference in Washington was doomed to failure. Finally, on February 6, 1937 Ecuador proposed a transactional line similar to the Herrera-Garcia Treaty for arbitration and asked for complete arbitration by the President of the United States if this is rejected. Peru promptly rejected this the next day and later the Peruvian Delegation passed a note to the Ecuadorian Delegation, which informed them that they had just received instructions from their government in Peru to abandon the negotiations. Because of this the President of the United States, Franklin D. Roosevelt, was not able to put a final solution to the border dispute through a peaceful arbitration. * July 6, 1936: Ulloa-Viteri Accord :This agreement established a

border line based on the effective possession of territory that each country had in the Amazon region at the time. This border was very similar to that established by the Rio de Janeiro Protocol 5 years later. To Ecuador, the status quo line simply demonstrated how much territory Peru had taken from Ecuador in the preceding century. Ecuador never considered this agreement a final treaty of borders, and continued its aspirations which were based on Gual-Larrea and Pedemonte-Mosquera.


Ecuadorian–Peruvian War (1941)

In 1941, the two countries went to war. As with all other such incidents, there are conflicting accounts to this day as to which side fired the first shot. Peru's version of events (notably well documented in Peruvian source

http://www.geocities.com/peruvictorsofcenepa/fap-1941.html]) is that Ecuador had been making incursions into its territory since 1937 and occupied several border locations by 1940. Given these circumstances, the President of Peru,
Manuel Prado Ugarteche Manuel Carlos Prado y Ugarteche (April 21, 1889 – August 15, 1967) was a banker who served twice as President of Peru. Son of former president Mariano Ignacio Prado, he was born in Lima and served as the nation's 43rd (1939 - 1945) and 46th (1 ...
, ordered the formation of the ''North Grouping'', a military unit in charge of the ''Northern Operational Theater'', on January 11, 1941, consisting of two light divisions with three battalions each, plus four other independent battalions and three artillery batteries (one with six 105 mm guns) (''Delgado''). In front of these forces, the Ecuadorian Border Security command had under its orders two Army battalions, the "Montecristi" and the "Cayambe", each one consisting of around 250 troops, armed with 7.92 mm Mauser rifles and a couple of Czech 7,92 mm ZB-26 light machine-guns, plus two

machine-guns. There was also a "Córdova" battalion, made up of around 100 troops, and a so-called "Mariscal Sucre" artillery battery, with 71 troops and no artillery pieces. In fact, the only artillery in the whole province of El Oro consisted of six Italian 65 mm mountain guns, sold to Ecuador as leftovers from the Great War, and almost without shells. These guns were never put into action. (''Rodríguez, 1943''). As for anti-aircraft defenses, the Ecuadorians had only a pair of 20 mm Breda guns deployed on Puerto Bolivar, which was the only port of entry for supplies, reinforcements, and weapons to arrive to the province, by sea, from the port-city of Guayaquil. The Ecuadorian Army of 1941 had not a single warplane. (''Rodríguez, 1943''). It is claimed that on Saturday, July 5, 1941, the

unit of the Ecuadorian army invaded Peruvian territory, an action which originated a combat that extended across the entire Zarumilla front, up to a region known as ''Quebrada Seca''. Ecuador's version of events is that Peru's invasion was an unprovoked act of aggression carried out with the explicit purpose of forcing Ecuador to sign an unfavorable treaty that would impose the status quo border line. A communiqué by Ecuador's Foreign Ministry indicated that Peruvian forces had been seen advancing north towards the border; all of the Peruvian troops stationed in Tumbes, Peru, Tumbes had left Zarumilla and those in

and other nearby sites were in turn advancing towards Zarumilla. According to the Ministry, the actions of the Ecuadorian army were limited to repelling the invasion which was occurring across much of the border

As support for its arguments Ecuador has repeatedly cited the obvious difference in military might between the two countries, and the lack of preparedness of its forces. It has been speculated that Peru prepared to carry out an all-out invasion and could have been simply waiting for the slightest provocation. Ecuador has also cited Peru's history of conflict with its other neighbors as evidence of its belligerence. It has been pointed out, however, that these circumstances did not preclude Ecuador from attempting to lay claim to territories it still considered its own. Also, during the

The much larger and better equipped Peruvian force of 13,000 men quickly overwhelmed the 1,800 Ecuadorian troops guarding the province of El Oro.

, dropping three paratroopers over the port-city of Puerto Bolívar (''Delgado''), one of them having been rescued by Ecuadorian fishermen when he landed on the waters of the Jambelí channel. This attempt was largely successful in allowing a relatively easy takeover of El Oro towns, devoid by then of any Ecuadorian military presence after the short-lived ceasefire of July 26, brokered by the mediator countries (USA, Brazil and Argentina). After the ceasefire, most of the Ecuadorian troops, by now exhausted and without ammunition, left the field of battle and made their way out of El Oro, towards the city of Cuenca. Thus, when Peru reopened the advance on July 29, which began with simultaneous bombings on the Ecuadorian towns of Machala, Puerto Bolívar, Pasaje, Santa Rosa, and Arenillas, plus a mission to the city of Guayaquil to drop leaflets, the Peruvian forces easily occupied the deserted towns of the province. A new ceasefire having been decreed to enter in effect on July 31 at 18h00 forced the Peruvian command to step up its efforts to occupy Machala and Puerto Bolívar, which they did with troops disembarked directly on Puerto Bolívar from the sea in the afternoon of July 31. (''Delgado'') Even then, hostilities didn't cease, as Peruvian forces began operations against the Ecuadorian posts on the Amazonian jungle, most of which were easily overrun.

Ecuador's objections to the Protocol and thesis of Nullity

Six times during the demarcation technical problems were found and referred to the Guarantors, with Brazil acting as lead. One of them, which involved the then contested ''Cordillera del Cóndor'', was submitted to arbitration by Captain Braz Dias de Aguiar. Both countries initially accepted the arbiter's award, issued July 1945, and demarcation began in the area according to that ruling. During 1943 and 1946 the

, the American community did not approve of Ecuador's diplomatic move, with the United States sending a letter of protest to Ecuador. The arguments for what is called Ecuador's ''thesis of nullity'' varied, but they were generally the following: * It was imposed by military force. * It was signed while Ecuadorian towns were under occupation; invasion and occupation of nation states are prohibited by international law. * International law does not accept the conquest of territory by force or violence. Even considering de facto possession (1936 status quo border line) Peru took about 14,000 km2 of territory. * There was lack of compliance by Peru in denying Ecuador free navigation in Amazonian rivers as stipulated. * It was a blow to the economic development of a South American country, which is contrary to existing pacts of cooperation. Peru's counter-arguments included the following: * Ecuador cannot unilaterally invalidate a protocol * The core argument on implementability is a demarcation issue, not a justification to invalidate the entire protocol * Peru disputes the notion that the protocol was imposed by ''premeditated'' military force * Even though the protocol was signed while Peruvian troops were still occupying El Oro for tactical reasons, the Ecuadorian congress ratified it long after Peruvian troops had left * Several Peruvian governments restricted the navigation clause in response to Ecuador's position on the treaty * On the issue of conquest of territory by force, Peru has pointed out that the disputed territories (Tumbes, Jaén and Maynas) were not under ''de jure'' Ecuadorian administration, and that the province of El Oro was not annexed to Peru Ecuador argued its thesis extensively for 30 years, but did not find support in the international community. Peru's position, on the other hand, was that a dispute did not exist at all after 1941, a position which lasted until 1995, when it was recognized as a problematic diplomatic issue. Maps published in Ecuador since the 1960s up to the end of the 20th century officially had to exclude the unmarked 78 kilometers of border, that is, the Rio Protocol line was drawn as unresolved, and to include what Ecuador considered as its own by right, according to the Pedemonte-Mosquera protocol (1830) line, which puts the Marañón (

Peace Declaration'' was signed on February 17, 1995. One of the declaration's clauses included the creation of the Military Observer Mission Ecuador-Peru (MOMEP) in order to verify ceasefire agreements, as well as observe and report infractions through diplomatic channels. The MOMEP contingent was made up of observers, logistics, and aviation support from the United States, Argentina, Brazil, and Chile as part of ''Operation Safe Border''. The mission, unique in its scope, was fully funded by Peru and Ecuador. MOMEP was largely successful despite several tragic accidents due to land mines left in the area. At a critical moment during late July and early August 1998 it appeared that Peruvian forces were preparing a preemptive assault on Ecuadorian forces (this is partially believed due to the Peruvian Air Force buying 19 Soviet-built

The guarantors assisted the parties in ministerial level discussions aimed at identifying the significant claims and disagreements of each side. Both countries agreed to a guarantor-sponsored technical commission composed of boundary experts in order to resolve the matter.

.) These delays nevertheless gave the guarantors more time to come up with a solution to the dispute. Eventually they concluded that a resolution would not be possible without granting something to each party. The commission recognized Ecuador's position on one small already demarcated section of the border, and Peru's position on the larger issue of the single watershed between the Zamora and Santiago rivers. The latter was a blow to Ecuador's historic position, and left Tiwintza in Peruvian territory. The solution that the commission reached was that an area of one square kilometer in the place of the fiercest struggle, Tiwinza, on the Peruvian side of the border, would be granted to Ecuador as a non-sovereign private property. The site could be used by Ecuador for commemorative and non-military events. Everyone born in Tiwinza will be considered Peruvian. Although none of the countries was completely satisfied with the solution, both accepted it, which was a significant diplomatic success. The resolution also called for the creation of two national parks contiguous to one another (also referred to as a ''binational park'') in the ''Cordillera del Condor'' region. Ambassador Luigi Einaudi, the US guarantor representative, is credited with coming up with the idea of a private property concession in Tiwintza, working almost full-time on the problem, and coming up with ways to express issues in a manner not offensive to either party

Aftermath

This dispute is unique and significant in the study of causes and resolution of international conflict. Ecuador and Peru are populated by people who share a language, a culture, a religious preference, have basically the same social and ethnic diversity, and comparable economic difficulties. They are also both democracies (for the most part in modern times) which puts in doubt the common contention that democracies never go to war with each other.


Education and public perception

A 2000 study carried out as part of the educational ''ASA Program'' found teaching curriculum relating to the dispute to be extremely one-sided in both countries: * Notably, in Ecuador the dispute is a central issue in the study of Ecuador's borders. (Traditionally there has been a course named "''History of Borders''.") * In Peru, the educational system does not give as much importance to the dispute with Ecuador, and is part of the course ''"Peruvian History"''. In contrast, the only topic related to the territorial dispute that is normally taught is the Rio Protocol, and its importance in the settlement of this dispute. Many examples of bias are cited, which can typically be characterized as removal of critical information about the other side's position. Emotional and nationalistic coloring of the material also appears to be routine. Although expected under the circumstances, this has likely fed the cycle of conflict in the past. Citizens of Ecuador and Peru feel both their countries have lost territory over time. The issue is one of overlapping maximalist territorial claims and aspirations. High Peruvian military spending is seen by Ecuador as evidence of belligerence and expansionism. Peru also considers Ecuador belligerent and expansionist. At the end of the 20th century things appear to have improved considerably. The
Cenepa War The Cenepa War (26 January – 28 February 1995), also known as the Alto Cenepa War, was a brief and localized military conflict between Ecuador and Peru, fought over control of an area in Peruvian territory (i.e. in the eastern side of the Cord ...
of 1995 allowed an honorable resolution of the conflict without a clear winner. To many Ecuadorians this was viewed as restoring the honor of the country, which was at least as important as their claims to the disputed territory. Unfortunately, not everyone is completely satisfied. Today, the entire Ecuadorian–Peruvian border is clearly delimited and demarcated, and the maps of both countries agree on the location of the common frontier. Bilateral work is being done by both countries Foreign Affairs officers to consolidate the economic and social integration. We can see part of this done by the Peruvian government with their Consulate in Machala, El Oro, where Minister Efrain Saavedra is the Consul General.

, has said peace is essential to South America's economic recovery. He added: "You clearly cannot have long-term growth and prosperity involving foreign investment without stability". While there are still political instability issues in the region, resolution of the territorial conflict is helpful. Trade between both countries has benefited considerably. Before signing the peace treaty, annual trade between Peru and Ecuador was about 100 million dollars. But as early as 1998, it had increased 5-fold. There was also a broad agreement of integration between both countries. It included a binational fund for peace and development, national plans for productive, social and environmental development, and so on.


Political implications

According to Gabriel Marcella ( US Department of National Security and Strategy), as a result of the Ecuadorian–Peruvian territorial dispute "a number of emerging views about international affairs, U.S. foreign policy, and modern inter-American affairs were either shattered or seriously challenged". Some of the global and regional political implications of the dispute which have been noted are the following: * It was a blow to the idea that democracies do not go to war with one another. An armed conflict between these two nations has existed well before then, nevertheless, on and off with major confrontations occurring in 1941, 1981 and 1995. Ecuador and Peru have both been full-fledged democracies for the most part in modern times, although of course not perfect or politically stable. * It was a blow to the idea that Latin America is a model for peaceful international relations. It is a reminder that there are other territorial disputes and conflicting claims among other Latin American countries which could potentially threaten peace in the region. * Civil-military relations in both countries have been impacted and need to be reexamined. If in fact the conflict was allowed to escalate after accidental encounters between patrols, it has been suggested that the civilian authority should perhaps assume more solid leadership and control. * The principle that territorial treaties in Latin America are not the result of force or violence needs to be reexamined as a result.
