Lithuania Biržai Vasa Privilege

Lithuania (; lt, Lietuva ), officially the Republic of Lithuania ( lt, Lietuvos Respublika, links=no ), is a country in the Baltic region of Europe. It is one of three Baltic states and lies on the eastern shore of the Baltic Sea. Lithuania shares land borders with Latvia to the north, Belarus to the east and south, Poland to the south, and Russia to the southwest. It has a maritime border with Sweden to the west on the Baltic Sea. Lithuania covers an area of , with a population of 2.8 million. Its capital and largest city is Vilnius; other major cities are Kaunas and Klaipėda. Lithuanians belong to the ethno-linguistic group of the Balts and speak Lithuanian, one of only a few living Baltic languages.

For millennia the southeastern shores of the Baltic Sea were inhabited by various Baltic tribes. In the 1230s, Lithuanian lands were united by Mindaugas, becoming king and founding the Kingdom of Lithuania on 6 July 1253. In the 14th century, the Grand Duchy of Lithuania was the largest country in Europe; present-day Lithuania, Belarus, most of Ukraine, and parts of Poland and Russia were all lands of the Grand Duchy. The Crown of the Kingdom of Poland and the Grand Duchy of Lithuania were in a '' de facto'' personal union from 1386 with the marriage of the Polish queen Hedwig and Lithuania's Grand Duke Jogaila, who was crowned King ''jure uxoris'' Władysław II Jagiełło of Poland. The Commonwealth of Poland and Lithuania was established by the Union of Lublin in July 1569. The Commonwealth lasted more than two centuries, until neighbouring countries dismantled it in 1772–1795, with the Russian Empire annexing most of Lithuania's territory. As World War I ended, Lithuania's Act of Independence was signed on 16 February 1918, founding the modern Republic of Lithuania. In World War II, Lithuania was occupied first by the Soviet Union and then by Nazi Germany. Towards the end of the war in 1944, when the Germans were retreating, the Soviet Union reoccupied Lithuania. Lithuanian armed resistance to the Soviet occupation lasted until the early 1950s. On 11 March 1990, a year before the formal dissolution of the Soviet Union, Lithuania passed the Act of the Re-Establishment of the State of Lithuania, becoming the first Soviet republic to proclaim its independence.

Lithuania is a developed country, with a high income advanced economy; ranking very high in the Human Development Index. It ranks favourably in terms of civil liberties, press freedom, internet freedom, democratic governance, and peacefulness. Lithuania is a member of the European Union, the Council of Europe, eurozone, the Nordic Investment Bank, Schengen Agreement, NATO and OECD. It participates in the Nordic-Baltic Eight (NB8) regional co-operation format and is a permanent observer of the Nordic Council.

Etymology

The first known record of the name of Lithuania ( lt, Lietuva) is in a 9 March 1009 story of Saint Bruno in the Quedlinburg Chronicle. The Chronicle recorded a Latinized form of the name Lietuva: ''Litua'' (pronounced ). Due to the lack of reliable evidence, the true meaning of the name is unknown. Nowadays, scholars still debate the meaning of the word and there are a few plausible versions.

Since ''Lietuva'' has a suffix (-''uva''), the original word should have no suffix. A likely candidate is ''Lietā''. Because many Baltic ethnonyms originated from hydronyms, linguists have searched for its origin among local hydronyms. Usually, such names evolved through the following process: hydronym → toponym → ethnonym.Zigmas Zinkevičius. Kelios mintys, kurios kyla skaitant Alfredo Bumblausko Senosios Lietuvos istoriją 1009-1795m. Voruta, 2005. Lietava, a small river not far from Kernavė, the core area of the early Lithuanian state and a possible first capital of the eventual Grand Duchy of Lithuania, is usually credited as the source of the name. However, the river is very small and some find it improbable that such a small and local object could have lent its name to an entire nation. On the other hand, such naming is not unprecedented in world history.

Artūras Dubonis proposed another hypothesis, that Lietuva relates to the word ''leičiai'' (plural of ''leitis''). From the middle of the 13th century, ''leičiai'' were a distinct warrior social group of the Lithuanian society subordinate to the Lithuanian ruler or the state itself. The word ''leičiai'' is used in the 14–16th century historical sources as an ethnonym for Lithuanians (but not Samogitians) and is still used, usually poetically or in historical contexts, in the Latvian language, which is closely related to Lithuanian.

History

The first people settled in the territory of Lithuania after the last glacial period in the 10th millennium BC: Kunda, Neman and Narva cultures. They were traveling hunters and did not form stable settlements. In the 8th millennium BC, the climate became much warmer, and forests developed. The inhabitants of what is now Lithuania then travelled less and engaged in local hunting, gathering and fresh-water fishing. Agriculture did not emerge until the 3rd millennium BC due to a harsh climate and terrain and a lack of suitable tools to cultivate the land. Crafts and trade also started to form at this time. Over a millennium, the Indo-Europeans, who arrived in the 3rd – 2nd millennium BC, mixed with the local population and formed various Baltic tribes.

The Baltic tribes did not maintain close cultural or political contacts with the Roman Empire, but they did maintain trade contacts (see Amber Road). Tacitus, in his study ''Germania'', described the Aesti people, inhabitants of the south-eastern Baltic Sea shores who were probably Balts, around the year 97 AD. The Western Balts differentiated and became known to outside chroniclers first. Ptolemy in the 2nd century AD knew of the Galindians and Yotvingians, and early medieval chroniclers mentioned Old Prussians, Curonians and Semigallians.

The Lithuanian language is considered to be very conservative for its close connection to Indo-European roots. It is believed to have differentiated from the Latvian language, the most closely related existing language, around the 7th century.Eidintas et al. (2013), p. 13 Traditional Lithuanian pagan customs and mythology, with many archaic elements, were long preserved. Rulers' bodies were cremated up until the conversion to Christianity: the descriptions of the cremation ceremonies of the grand dukes Algirdas and Kęstutis have survived.Eidintas et al. (2013), pp. 24–25

Grand Duchy of Lithuania

From the 9th to the 11th centuries, coastal Balts were subjected to raids by the Vikings, and the kings of Denmark collected tribute at times. During the 10–11th centuries, Lithuanian territories were among the lands paying tribute to Kievan Rus', and Yaroslav the Wise was among the Ruthenian rulers who invaded Lithuania (from 1040). From the mid-12th century, it was the Lithuanians who were invading Ruthenian territories. In 1183, Polotsk and Pskov were ravaged, and even the distant and powerful Novgorod Republic was repeatedly threatened by the excursions from the emerging Lithuanian war machine toward the end of the 12th century.

From the late 12th century, an organized Lithuanian military force existed; it was used for external raids, plundering and the gathering of slaves. Such military and pecuniary activities fostered social differentiation and triggered a struggle for power in Lithuania. This initiated the formation of early statehood, from which the Grand Duchy of Lithuania developed. The disparate Lithuanian tribes along the Nemunas were united into the Lithuanian state by 1219, at the latest. The only Lithuanian Roman Catholic king, Mindaugas, was baptised as a Roman Catholic in 1251 and crowned as King of Lithuania on 6 July 1253. Tomas Baranauskas (2001)

After his assassination in 1263, pagan Lithuania was a target of the Christian crusades of the Teutonic Knights and the Livonian Order. Siege of Pilėnai is noted for the Lithuanians' defense against the intruders. Despite the devastating century-long struggle with the Orders, the Grand Duchy of Lithuania expanded rapidly, overtaking former Ruthenian principalities of Kievan Rus'.

On 22 September 1236, the Battle of Saulė between Samogitians and the Livonian Brothers of the Sword took place close to Šiauliai. The Livonian Brothers were defeated during it and their further conquest of the Balts lands were stopped. The battle inspired rebellions among the Curonians, Semigallians, Selonians, Oeselians, tribes previously conquered by the Sword-Brothers. Some thirty years' worth of conquests on the left bank of Daugava were lost. In 2000, the Lithuanian and Latvian parliaments declared 22 September to be the Day of Baltic Unity.

According to the legend, Grand Duke Gediminas was once hunting near the Vilnia River; tired after the successful hunt, he settled in for the night and dreamed of a huge Iron Wolf standing on top a hill and howling as strong and loud as a hundred wolves. ''Krivis'' (pagan priest) Lizdeika interpreted the dream that the Iron Wolf represents Vilnius Castles. Gediminas, obeying the will of the gods, built the city and gave it the name Vilnius – from the stream of the Vilnia River.

In 1362 or 1363, Grand Duke Algirdas achieved a decisive victory in the Battle of Blue Waters against the Golden Horde and stopped its further expansion in the present-day Ukraine. The victory brought the city of Kyiv and a large part of present-day Ukraine, including sparsely populated Podolia and Dykra, under the control of the expanding Grand Duchy of Lithuania. After taking Kyiv, Lithuania became a direct neighbor and rival of the Grand Duchy of Moscow.

By the end of the 14th century, Lithuania was one of the largest countries in Europe and included present-day Belarus, Ukraine, and parts of Poland and Russia. The geopolitical situation between the west and the east determined the multicultural and multi-confessional character of the Grand Duchy of Lithuania. The ruling elite practised religious tolerance and the Chancery Slavonic language was used as an auxiliary language to Latin for official documents.

In 1385, the Grand Duke Jogaila accepted Poland's offer to become its king. Jogaila embarked on gradual Christianization of Lithuania and established a personal union between Poland and Lithuania. Lithuania was one of the last pagan areas of Europe to adopt Christianity. While territories to the north had been Christianized in 1186 by Western merchants and missionaries who formed the Order of the Brothers and the Sword to spread Christianity through military organization, the Lithuanians had defeated the Order's militant efforts in 1236.

After two civil wars, Vytautas the Great became the Grand Duke of Lithuania in 1392. During his reign, Lithuania reached the peak of its territorial expansion, centralization of the state began, and the Lithuanian nobility became increasingly prominent in state politics. In the great Battle of the Vorskla River in 1399, the combined forces of Tokhtamysh and Vytautas were defeated by the Mongols. Thanks to close cooperation, the armies of Lithuania and Poland achieved a victory over the Teutonic Knights in 1410 at the Battle of Grunwald, one of the largest battles of medieval Europe.

In January 1429, at the Congress of Lutsk Vytautas received the title of King of Lithuania with the backing of Sigismund, Holy Roman Emperor, but the envoys who were transporting the crown were stopped by Polish magnates in autumn of 1430. Another crown was sent, but Vytautas died in the Trakai Island Castle several days before it reached Lithuania. He was buried in the Cathedral of Vilnius.

After the deaths of Jogaila and Vytautas, the Lithuanian nobility attempted to break the union between Poland and Lithuania, independently selecting Grand Dukes from the Jagiellon dynasty. But, at the end of the 15th century, Lithuania was forced to seek a closer alliance with Poland when the growing power of the Grand Duchy of Moscow threatened Lithuania's Russian principalities and sparked the Muscovite–Lithuanian Wars and the Livonian War.

On 8 September 1514, the Battle of Orsha between Lithuanians, commanded by the Grand Hetman Konstanty Ostrogski, and Muscovites was fought. According to '' Rerum Moscoviticarum Commentarii'' by Sigismund von Herberstein, the primary source for information on the battle, the much smaller army of Poland–Lithuania (under 30,000 men) defeated a force of 80,000 Muscovite soldiers, capturing their camp and commander. The battle destroyed a military alliance against Lithuania and Poland. Thousands of Muscovites were captured as prisoners and used as labourers in the Lithuanian manors, while Konstanty Ostrogski delivered the captured Muscovite flags to the Cathedral of Vilnius.

The Livonian War was ceased for ten years with a Truce of Yam-Zapolsky signed on 15 January 1582 according to which the already Polish–Lithuanian Commonwealth recovered Livonia, Polotsk and Velizh, but transferred Velikiye Luki to the Tsardom of Russia. The truce was extended for twenty years in 1600, when a diplomatic mission to Moscow led by Lew Sapieha concluded negotiations with Tsar Boris Godunov. The truce was broken when the Poles invaded Muscovy in 1605.

Polish–Lithuanian Commonwealth

The Polish–Lithuanian Commonwealth was created in 1569 by the Union of Lublin. As a member of the Commonwealth, Lithuania retained its institutions, including a separate army, currency, and statutory laws – the Statute of Lithuania. Eventually Polonization affected all aspects of Lithuanian life: politics, language, culture, and national identity. From the mid-16th to the mid-17th centuries, culture, arts, and education flourished, fueled by the Renaissance and the Protestant Reformation. From 1573, the Kings of Poland and Grand Dukes of Lithuania were elected by the nobility, who were granted ever-increasing Golden Liberties. These liberties, especially the '' liberum veto'', led to anarchy and the eventual dissolution of the state.

The Commonwealth reached its Golden Age in the early 17th century. Its powerful parliament was dominated by nobles who were reluctant to get involved in the Thirty Years' War; this neutrality spared the country from the ravages of a political-religious conflict that devastated most of contemporary Europe. The Commonwealth held its own against Sweden, the Tsardom of Russia, and vassals of the Ottoman Empire, and even launched successful expansionist offensives against its neighbours. In several invasions during the Time of Troubles, Commonwealth troops entered Russia and managed to take Moscow and hold it from 27 September 1610 to 4 November 1612, when they were driven out after a siege.

In 1655, after the extinguishing battle, for the first time in history the Lithuanian capital Vilnius was taken by a foreign army. The Russian army looted the city, splendid churches, and manors. Between 8,000 and 10,000 citizens were killed; the city burned for 17 days. Those who returned after the catastrophe could not recognise the city. The Russian occupation of the Grand Duchy of Lithuania lasted up to 1661. Many artefacts and cultural heritage were either lost or looted, significant parts of the state archive – Lithuanian Metrica, collected since the 13th century, were lost and the rest was moved out of the country. During the Northern Wars (1655–1661), the Lithuanian territory and economy were devastated by the Swedish army. Almost all territory of the Grand Duchy of Lithuania was occupied by Swedish and Russian armies. This period is known as ''Tvanas'' ( The Deluge).

Before it could fully recover, Lithuania was ravaged during the Great Northern War (1700–1721). The war, a plague, and a famine caused the deaths of approximately 40% of the country's population. Foreign powers, especially Russia, became dominant in the domestic politics of the Commonwealth. Numerous fractions among the nobility used the Golden Liberties to prevent any reforms.

The Constitution of 3 May 1791 was adopted by the Great Sejm (parliament) of the Polish–Lithuanian Commonwealth trying to save the state. The legislation was designed to redress the Commonwealth's political defects due to the system of Golden Liberties, also known as the "Nobles' Democracy," which had conferred disproportionate rights on the nobility (Szlachta) and over time had corrupted politics. The constitution sought to supplant the prevailing anarchy fostered by some of the country's magnates with a more democratic constitutional monarchy. It introduced elements of political equality between townspeople and nobility, and placed the peasants under the protection of the government, thus mitigating the worst abuses of serfdom. It banned parliamentary institutions such as the ''liberum veto'', which had put the Sejm at the mercy of any deputy who could revoke all the legislation that had been passed by that Sejm. It was drafted in relation to a copy of the United States Constitution. It is regarded as the world's second-oldest codified national governmental constitution after the 1787 U.S. Constitution.

Russian Empire

Eventually, the Commonwealth was partitioned in 1772, 1793, and 1795 by the Russian Empire, Prussia, and the Habsburg monarchy.

The largest area of Lithuanian territory became part of the Russian Empire. After the unsuccessful uprisings in 1831 and 1863, the Tsarist authorities implemented a number of Russification policies. In 1840 the Third Statute of Lithuania was abolished. They banned the Lithuanian press, closed cultural and educational institutions and made Lithuania part of a new administrative region called Northwestern Krai. The Russification failed, owing to an extensive network of Lithuanian book smugglers and secret Lithuanian homeschooling.

After the Russo-Turkish War (1877–1878), when German diplomats assigned what were seen as Russian spoils of war to Turkey, the relationship between Russia and the German Empire became complicated. The Russian Empire resumed the construction of fortresses at its western borders for defence against a potential invasion from Germany in the West. On 7 July 1879 the Russian Emperor Alexander II approved a proposal from the Russian military leadership to build the largest "first-class" defensive structure in the entire state – the Kaunas Fortress. Large numbers of Lithuanians went to the United States in 1867–1868 after a famine.

Simonas Daukantas promoted a return to Lithuania's pre-Commonwealth traditions, which he depicted as a Golden Age of Lithuania and a renewal of the native culture, based on the Lithuanian language and customs. With those ideas in mind, he wrote already in 1822 a history of Lithuania in Lithuanian – ''Darbai senųjų lietuvių ir žemaičių'' (''The Deeds of Ancient Lithuanians and Samogitians''), though it was not published at that time. A colleague of S. Daukantas, Teodor Narbutt wrote in Polish a voluminous ''Ancient History of the Lithuanian Nation'' (1835–1841), where he likewise expounded and expanded further on the concept of historic Lithuania, whose days of glory had ended with the Union of Lublin in 1569. Narbutt, invoking German scholarship, pointed out the relationship between the Lithuanian and Sanskrit languages. A Lithuanian National Revival, inspired by the ancient Lithuanian history, language and culture, laid the foundations of the modern Lithuanian nation and independent Lithuania.

20th and 21st centuries

1918–1939

As a result of the Great Retreat during World War I, Germany occupied the entire territory of Lithuania and Courland by the end of 1915. A new administrative entity, Ober Ost, was established. Lithuanians lost all political rights they had gained: personal freedom was restricted, and at the beginning, the Lithuanian press was banned. However, the Lithuanian intelligentsia tried to take advantage of the existing geopolitical situation and began to look for opportunities to restore Lithuania's independence. On 18–22 September 1917, the Vilnius Conference elected the 20-member Council of Lithuania. The council adopted the Act of Independence of Lithuania on 16 February 1918 which proclaimed the restoration of the independent state of Lithuania governed by democratic principles, with Vilnius as its capital. The state of Lithuania which had been built within the framework of the Act lasted from 1918 until 1940.

Following the capitulation of Germany in November 1918, the first Provisional Constitution of Lithuania was adopted and the first government of Prime Minister Augustinas Voldemaras was organized. At the same time, the army and other state institutions began to be organized. Lithuania fought three wars of independence: against the Bolsheviks who proclaimed the Lithuanian Soviet Socialist Republic, against the Bermontians, and against Poland. As a result of the staged Żeligowski's Mutiny in October 1920, Poland took control of Vilnius Region and annexed it as Wilno Voivodeship in 1922. Lithuania continued to claim Vilnius as its '' de jure'' capital (the '' de facto'', provisional capital being Kaunas) and relations with Poland remained particularly tense and hostile for the entire interwar period. In January 1923, Lithuania staged the Klaipėda Revolt and captured Klaipėda Region (Memel territory) which was detached from East Prussia by the Treaty of Versailles. The region became an autonomous region of Lithuania.

On 15 May 1920, the first meeting of the democratically elected constituent assembly took place. The documents it adopted, i. e. the temporary (1920) and permanent (1922) constitutions of Lithuania, strove to regulate the life of the new state. Land, finance, and educational reforms started to be implemented. The currency of Lithuania, the Lithuanian litas, was introduced. The University of Lithuania was opened. All major public institutions had been established. As Lithuania began to gain stability, foreign countries started to recognize it. In 1921 Lithuania was admitted to the League of Nations.

On 17 December 1926, a military coup d'état took place, resulting in the replacement of the democratically elected government with a conservative authoritarian government led by Antanas Smetona. Augustinas Voldemaras was appointed to form a government. The so-called authoritarian phase had begun strengthening the influence of one party, the Lithuanian Nationalist Union, in the country. In 1927, the Seimas was dissolved. A new constitution was adopted in 1928, which consolidated presidential powers. Gradually, opposition parties were banned, censorship was tightened, and the rights of national minorities were narrowed. The only democratically elected body that continued to exist at the time was a Parliament of the Klaipėda Region.

On 15 July 1933, Steponas Darius and Stasys Girėnas, Lithuanian pilots, emigrants to the United States, made a significant flight in the history of world aviation. They flew across the Atlantic Ocean, covering a distance of without landing, in 37 hours and 11 minutes (). In terms of comparison, as far as the distance of non-stop flights was concerned, their result ranked second only to that of Russell Boardman and John Polando.

The provisional capital Kaunas, which was nicknamed ''Little Paris'', and the country itself had a Western standard of living with sufficiently high salaries and low prices. At the time, qualified workers there were earning very similar real wages as workers in Germany, Italy, Switzerland and France, the country also had a surprisingly high natural increase in population of 9.7 and the industrial production of Lithuania increased by 160% from 1913 to 1940.

The situation was aggravated by the global economic crisis. The purchase price of agricultural products had declined significantly. In 1935, farmers began strikes in Suvalkija and Dzūkija. In addition to economic ones, political demands were made. The government cruelly suppressed the unrest. In the spring of 1936, four peasants were sentenced to death for starting the riots.

1939–1944

On 20 March 1939, after years of rising tensions, Lithuania was handed an ultimatum by Nazi Germany demanding it relinquish the Klaipėda Region. Two days later, the Lithuanian government accepted the ultimatum. When Nazi Germany and Soviet Union concluded the Molotov–Ribbentrop Pact, Lithuania was initially assigned to the German sphere of influence but was later transferred to the Soviet sphere. At the outbreak of World War II, Lithuania declared neutrality.

In October 1939, Lithuania was forced to sign the Soviet–Lithuanian Mutual Assistance Treaty: five Soviet military bases with 20,000 troops were established in Lithuania in exchange for Vilnius, which the Soviets had captured from Poland. Delayed by the Winter War with Finland, the Soviets issued an ultimatum to Lithuania on 14 June 1940. They demanded the replacement of the Lithuanian government and that the Red Army be allowed into the country. The government decided that, with Soviet bases already in Lithuania, armed resistance was impossible and accepted the ultimatum. President Smetona left the country, hoping to form a government in exile, while more than 200,000 Soviet Red Army soldiers crossed the Belarus–Lithuania border. The next day, identical ultimatums were presented to Latvia and Estonia. The Baltic states were occupied. The Soviets followed semi-constitutional procedures for transforming the independent countries into soviet republics and incorporating them into the Soviet Union.

Vladimir Dekanozov was sent to supervise the formation of the puppet People's Government and the rigged election to the People's Seimas. The Lithuanian Soviet Socialist Republic was proclaimed on 21 July and accepted into the Soviet Union on 3 August. Lithuania was rapidly Sovietized: political parties and various organizations (except the Communist Party of Lithuania) were outlawed, some 12,000 people, including many prominent figures, were arrested and imprisoned in Gulag as "enemies of the people", larger private property was nationalized, the Lithuanian litas was replaced by the Soviet rouble, farm taxes were increased by 50–200%, the Lithuanian Army was transformed into the 29th Rifle Corps of the Red Army. On 14–18 June 1941, less than a week before the Nazi invasion, some 17,000 Lithuanians were deported to Siberia, where many perished due to inhumane living conditions (see the June deportation). The occupation was not recognized by Western powers and the Lithuanian Diplomatic Service, based on pre-war consulates and legations, continued to represent independent Lithuania until 1990.

When Nazi Germany attacked the Soviet Union on 22 June 1941, Lithuanians began the anti-Soviet June Uprising, organized by the Lithuanian Activist Front. Lithuanians proclaimed independence and organized the Provisional Government of Lithuania. This government quickly self-disbanded. Lithuania became part of the Reichskommissariat Ostland, German civil administration.

By 1 December 1941, over 120,000 Lithuanian Jews, or 91–95% of Lithuania's pre-war Jewish community, had been killed. Nearly 100,000 Jews, Poles, Russians and Lithuanians were murdered at Paneriai. However, thousands of Lithuanian families risking their lives also protected Jews from the Holocaust. Israel has recognized 918 Lithuanians (as of 1 January 2021) as Righteous Among the Nations for risking their lives to save Jews during the Holocaust.

Approximately 13,000 men served in the Lithuanian Auxiliary Police Battalions. 10 of the 26 Lithuanian Auxiliary Police Battalions working with the Nazi Einsatzkommando, were involved in the mass killings. Rogue units organised by Algirdas Klimaitis and supervised by SS ''Brigadeführer'' Walter Stahlecker started the Kaunas pogrom in and around Kaunas on 25 June 1941. In 1941, the Lithuanian Security Police (''Lietuvos saugumo policija''), subordinate to Nazi Germany's Security Police and Nazi Germany's Criminal Police, was created. The ''Lietuvos saugumo policija'' targeted the communist underground.

A new occupation had begun. Nationalized assets were not returned to the residents. Some of them were forced to fight for Nazi Germany or were taken to German territories as forced labourers. Jewish people were herded into ghettos and gradually killed by shooting or sending them out to concentration camps.

1944–1990

After the retreat of the German armed forces, the Soviets reestablished their control of Lithuania in July–October 1944. The massive deportations to Siberia were resumed and lasted until the death of Stalin in 1953. Antanas Sniečkus, the leader of the Communist Party of Lithuania from 1940 to 1974, supervised the arrests and deportations. All Lithuanian national symbols were banned. Under the pretext of Lithuania's economic recovery, the Moscow authorities encouraged the migration of workers and other specialists to Lithuania with the intention to further integrate Lithuania into the Soviet Union and to develop the country's industry. At the same time, Lithuanians were lured to work in the USSR by promising them all the privileges of settling in a new place.

The second Soviet occupation was accompanied by the guerrilla warfare of the Lithuanian population, which took place in 1944–1953. It sought to restore an independent state of Lithuania, to consolidate democracy by destroying communism in the country, returning national values and the freedom of religion. About 50,000 Lithuanians took to the forests and fought Soviet occupants with a gun in their hands. In the later stages of the partisan war, Lithuanians formed the Union of Lithuanian Freedom Fighters and its leader Jonas Žemaitis (codename Vytautas) was posthumously recognized as the president of Lithuania. Despite the fact that the guerrilla warfare did not achieve its goal of liberating Lithuania and that it resulted in more than 20,000 deaths, the armed resistance ''de facto'' demonstrated that Lithuania did not voluntarily join the USSR and it also legitimized the will of the people of Lithuania to be independent. Lithuanian courts and the ECHR both treat the Soviets' annihilation of the Lithuanian partisans as a genocide.

Even with the suppression of partisan resistance, the Soviet government failed to stop the movement for the independence of Lithuania. The underground dissident groups were active publishing the underground press and Catholic literature. The most active participants of the movement included Vincentas Sladkevičius, Sigitas Tamkevičius and Nijolė Sadūnaitė. In 1972, after Romas Kalanta's public self-immolation, the unrest in Kaunas lasted for several days.

The Helsinki Group, which was founded in Lithuania after the international conference in Helsinki (Finland), where the post-WWII borders were acknowledged, announced a declaration for Lithuania's independence on foreign radio station. The Helsinki Group informed the Western world about the situation in the Soviet Lithuania and violations of human rights. With the beginning of the increased openness and transparency in government institutions and activities (''glasnost'') in the Soviet Union, on 3 June 1988, the Sąjūdis was established in Lithuania with Romualdas Ozolas
