and the First Brazilian Republic over the Acre Region, which was rich in rubber and gold deposits. The conflict had two phases between 1899 and 1903 and ended with an Acrean victory and the subsequent Treaty of Petrópolis, which ceded Acre to Brazil. The outcome also affected territories disputed with Peru.

Causes

The region of Acre possessed rich gold deposits and an abundance of timber, principally rubber trees. From the end of the 19th century until the middle of the 20th century, rubber trees were crucial to the automobile and transport industry, as synthetic rubber for the manufacture of tires and other objects was not discovered until around World War II. It is because of this that the war is also referred to as the Rubber War (''Guerra del Caucho''), as one of the motives that drove Jefferson José Torres, Governor of

When the price of rubber rose significantly in the late 19th century, about 18,000 adventurers and settlers, most from Brazil, went to

to exploit the rubber trees. There were practically no roads so that the main means of transport were some river steamers, canoes and rafts.

First "Republic of Acre"

On January 2, 1899, Bolivia set up a customs office in Puerto Alonso (today Porto Acre), which upset the Brazilian settlers, who wanted to oust the Bolivian authorities. A lawyer, Dr. José de Carvalho, led a revolt against the Bolivians on April 30, 1899. Pressured by José de Carvalho, Bolivians were forced to leave the region. To prevent their return, the governor of Amazonas, José Cardoso Ramalho Junior, organized a team to enter Acre; commanded by Spaniard

Luis Gálvez Rodríguez de Arias Luis Gálvez Rodríguez de Arias was a Spanish journalist, diplomat and adventurer who proclaimed the Republic of Acre in 1899. He ruled Acre between July 14, 1899 and January 1, 1900 for the first time, and between January 30 and March 15, 1900, ...

, who served as a Bolivian consul in Belém. Gálvez left Manaus on June 4, 1899, and came to the Bolivian town of Puerto Alonso, which had its name changed to Porto Acre, where he proclaimed the Republic of Acre on July 14, 1899, discreetly supported by willing '' amazonense'' officialdom, imposing his authority on the lands that the Treaty of Ayacucho (1867) had entrusted to Bolivia. Bolivia responded by sending a force of 500 men. Before his arrival, Galvez was taken prisoner by Antonio de Sousa Braga, who declared himself president of Acre. Shortly afterwards, however, he ceded power to Gálvez. On March 15, 1900, a Brazilian war flotilla reached Puerto Alonso, arrested Galvez and dissolved the Republic of Acre; as the Brazilian government, based on the Treaty of Ayacucho, considered Acre as Bolivian territory. A further reason for Ramalho Junior's interest in Acres occupation was that Galvez had discovered the existence of a diplomatic agreement between Bolivia and the United States stating that there would be military support for Bolivia in the event of war with Brazil.

Second "Republic of Acre"

At that time, Bolivia organized a small military mission to occupy the region. Arriving in Porto Acre, it was prevented from continuing its movement by Brazilian rubber tappers.

In November 1900 there was another rebellion in order to take Acre from Bolivia and create an independent republic. Known as the "Expedition of Poets" or "Expedition Floriano Peixoto", this force, under the command of journalist Orlando Correa Lopes, was based on the river monitor ''Dovapor Solimões'', equipped with the help of the governor of Amazonas province, Silvério José Néri. The Solimões operated on the Purus river and seized the vessel ''Alonso'', which was renamed ''Ruy Barbosa''. Carvalho Rodrigo became president of the newly declared Republic of Acre, whose forces had a light cannon, a machine gun and about 200 men. Around Christmas 1900, this force attacked Puerto Alonso and was defeated by the Bolivian military, resulting in the loss of a dozen men and the machine gun, eventually leading to the dissolution of the republic. On December 29, the Bolivian vessel ''Rio Afua'' strengthened the garrison of Puerto Alonso. Although Bolivia deny the agreement with the United States previously mentioned, on June 11, 1901

signed a lease with a Bolivian Trading Company (also known as "Bolivian Syndicate of New York City", or simply "Bolivian Syndicate"), based in

Jersey City Jersey City is the second-most populous city in the U.S. state of New Jersey, after Newark.New Jersey. The company had some very influential shareholders, including the king of Belgium and relatives of William McKinley, then president of the United States. Bolivia had given the company almost total control over the Acre province to protect its sovereignty. Under the agreement, the group of U.S. and British capitalists would assume total control over the region, occupying and exploiting it for 30 years. At that time Bolivia was ruled by General

. The number of Brazilians in the region grew, searching forest wealth, mainly in the northeast. Brazil and Peru, which also claimed the territory, strongly disapproved of the lease act. Brazil withdrew the consul of Puerto Alonso and closed the tributaries of the Amazon River to trade with Bolivia. The international powers, who considered the basin as international waters, protested, leading Brazil to reduce the ban to war materials and release the Bolivian goods addressed to foreign nations. placido1

At 26 years old, having fought in the Federalist Revolution, the gaucho José Plácido de Castro came to Amazon. In 1902, rubber tappers made a deal with Castro. The military, believing that it could profit from the border struggle, offered Castro to train and command 2000 tappers to fight the Bolivians. At 5 o'clock in the morning of August 6, 1902, Castro led 33 riflemen in canoes on the Acre River. Castro quietly entered a wooden house in the city of

, in which the Bolivian quartermaster depot was based. Soon, Castro took possession of the site and imprisoned the Bolivian military personnel. The local people mistook the group as part of the celebrations of the Bolivian Independence Day. On September 18, a Bolivian battalion of 180 men, led by Colonel Rosendo Rojas, surprised the forces of Castro, which now had about 70 men. The Brazilians, armed with Winchester rifles, low on ammunition and suffering from tropical diseases and desertions, lost twenty men and were defeated. Castro then recruited another force, with about a thousand men. Part of that force besieged the city of Puerto Alonso on May 19, 1902. On October 14, the force captured some external fortifications and captured the ''Río Afua'', which wrecked on the island during the fighting. The river vessel, renamed ''Independence'', was used against its former owners. Despite the setback, the Bolivians obstinately kept Puerto Alonso. Elsewhere, the Brazilian adventurers besieged Company, which capitulated on 15 October. Other battles, almost all won by the forces of Plácido occurred in Bom Destino, Santa Rosa and other coastal cities. On January 15, 1903, the Brazilian force attacked and captured some positions out of Puerto Alonso. The ''Independence'', anchored upriver, was charged with thirty tons of high-quality rubber and focused on the passage by the Bolivian batteries to bring the river rubber down, which could be sold. The Plácido forces used the money to buy weapons and ammunition. On January 24, the Bolivians in Puerto Alonso surrendered to the rebels, who had taken the entire region. Three days later, on January 27, the Third Republic of Acre was proclaimed, now with the support of President Rodrigues Alves and his Foreign Minister, the Baron of Rio Branco, who ordered the Acre occupation and established a military government under the command of General Olimpio da Silveira. The besieging force advanced towards the place where the rivers Chipamanu (also called Manuripe) and Tahuamanu meet to form the Rio Orton. Soon, a Bolivian force under the command of General Jose Manuel Pando, the Bolivian President, took the opposite bank. However, before it did any significant combat, as a result of the excellent work of diplomacy by the Baron of Rio Branco, the governments of Brazil and Bolivia signed a preliminary treaty on March 21, 1903; finally ratifying the Treaty of Petrópolis on November 11, 1903. By said treaty Bolivia gave up Acre in exchange for Brazilian territory from the

Joaquim Francisco de Assis Brazil actively participated in the negotiations with Bolivia, representing the Brazilian government in its signature. The Bolivian Syndicate was compensated with 110,000 pounds (~ $35 million réis). The taxes collected from Brazilian Acre financed the damages and the loan for the construction of the railway over a course of 30 years. The first of Placido Castro's decrees took place on January 26, 1903, applying Brazilian law until the enactment of a state constitution. It considered valid all land titles issued by Bolivia or the state of Amazonas, defined the Portuguese language as official and adopted the Brazilian monetary standard. The Treaty of Petrópolis, signed in 1903 by the Baron of Rio Branco and Assis Brazil, was approved by Brazilian federal law on February 25, 1904, and regulated by a presidential decree of April 7, 1904, incorporating Acre as part of Brazil. Placido de Castro, who died on August 11, 1908, was the first president of the Acre Territory. Castro, the Baron of Rio Branco and Assis Brazil became namesakes of the state capital ( Rio Branco) and two counties (Assis Brazil and Plácido de Castro). The Acrean Revolution demonstrated Brazil's advantage over their neighbors because of its downstream location in relation to the rivers that run almost the entire continent, being born in the Andes and flowing into the Atlantic Ocean. Brazil could send reinforcements to the disputed area by the rivers, while the Bolivians had to cross the Andes. Apparently, the Bolivian effort was fully funded by the rubber barons, particularly

Treaty of Petrópolis

In 1867 the "Treaty of Peace and Friendship", or Ayacucho Bolivia Treaty, had yielded 164,242 square kilometers of area which were annexed by Brazil to the then-province and present state of Amazonas. The Treaty of Petrópolis is a peace treaty signed between Bolivia and Brazil in the Brazilian city of Petrópolis on November 17, 1903. Bolivia yielded an approximate area of 191,000 square kilometers, which mainly correspond to the current state of Acre, Brazil.
