Antanas Smetona was a Lithuanian intellectual, journalist and politician who served as the first president of Lithuania from 1919 to 1920 and again from 1926 until the Soviet occupation of Lithuania in 1940. Referred to as the "Leader of the Nation" during his presidency, Smetona is recognised as one of the most important Lithuanian political figures between World War I and World War II, and a prominent ideologists of Lithuanian nationalism and the movement for national revival.
The Lithuanian Soviet Socialist Republic, also known as Soviet Lithuania or simply Lithuania, was de facto one of the constituent republics of the Soviet Union between 1940–1941 and 1944–1990. After 1946, its territory and borders mirrored those of today's Republic of Lithuania, with the exception of minor adjustments to its border with Belarus.
The prime minister of Lithuania is the head of the government of Lithuania. The prime minister is Lithuania's head of government and is appointed by the president with the assent of the Lithuanian parliament, the Seimas. The modern office of prime minister was established in 1990, when Lithuania declared its independence, although the official title was "Chairperson of the Council of Ministers" until 25 November 1992.
Antanas Merkys was the last Prime Minister of independent Lithuania, serving from November 1939 to June 1940. When the Soviet Union presented an ultimatum to Lithuania demanding that it accept a Soviet garrison, President Antanas Smetona fled the country leaving Merkys as acting president. Merkys ostensibly cooperated with the Soviets, and illegally took over the presidency in his own right. After three days, Merkys handed power to Justas Paleckis, who formed the People's Government of Lithuania. When Merkys attempted to flee the country, he was captured and deported to the interior of Russia, where he died in 1955.
Justas Paleckis was a Lithuanian Soviet author, journalist and politician. He was nominal acting president of Lithuania after the Soviet invasion while Lithuania was still ostensibly independent, in office from 17 June to 3 August 1940. He then remained the head of state of the Lithuanian SSR until 1967.
Leonas Bistras was one of the most prominent Lithuanian politicians of the interwar period. A Christian Democrat, he was in 1925 appointed Prime Minister of Lithuania. Bistras also headed the ministries of education, defense and foreign affairs in several different governments throughout 1920s and 1930s and twice served as the speaker of the Lithuanian parliament, the Seimas. After the 1926 Lithuanian coup d'état and the subsequent fall of parliamentary democracy, Bistras led the Christian Democrats and, despite persecution, acted as an outspoken leader of the opposition to the authoritarian President Antanas Smetona.
The Act of the Re-Establishment of the State of Lithuania or Act of March 11 was an independence declaration by Lithuania adopted on March 11, 1990, signed by all members of the Supreme Council of the Republic of Lithuania led by Sąjūdis. The act emphasized restoration and legal continuity of the interwar-period Lithuania, which was occupied by the Soviet Union and annexed in June 1940. In March, 1990, it was the first of the 15 Soviet republics to declare independence, with the rest following to continue for 21 months, concluding with Kazakhstan's independence in 1991. These events led to the dissolution of the Soviet Union in December 1991.
The three Baltic countries, or the Baltic states – Estonia, Latvia, and Lithuania – are held to have continued as legal entities under international law while under the Soviet occupation from 1940 to 1991, as well as during the German occupation in 1941–1944/1945. The prevailing opinion accepts the Baltic thesis of illegal occupation and the actions of the USSR are regarded as contrary to international law in general and to the bilateral treaties between the USSR and the three Baltic countries in particular.
The 1926 Lithuanian coup d'état was a military coup d'état in Lithuania that replaced the democratically elected government with a nationalist regime led by Antanas Smetona. The coup took place on 17 December 1926 and was largely organized by the military; Smetona's role remains the subject of debate. The coup brought the Lithuanian Nationalist Union, the most conservative party at the time, to power. Previously it had been a fairly new and insignificant nationalistic party. By 1926, its membership reached about 2,000 and it had won only three seats in the parliamentary elections. The Lithuanian Christian Democratic Party, the largest party in the Seimas at the time, collaborated with the military and provided constitutional legitimacy to the coup, but accepted no major posts in the new government and withdrew in May 1927. After the military handed power over to the civilian government, it ceased playing a direct role in political life.
The Third Seimas of Lithuania was the third parliament (Seimas) democratically elected in Lithuania after it declared independence on 16 February 1918. The elections took place on 8–10 May 1926. For the first time the Lithuanian Christian Democratic Party were forced to remain in opposition. The coalition government made some unpopular decisions and was sharply criticized. Regular Seimas work was interrupted by a military coup d'état in December 1926 when the democratically elected government was replaced with the authoritarian government of Antanas Smetona and Augustinas Voldemaras. The Third Seimas was dissolved on 12 March 1927 and new elections were not called until 1936.
The Fourth Seimas of Lithuania was the fourth parliament (Seimas) elected in Lithuania after it declared independence on 16 February 1918. The elections took place on 9 and 10 June 1936, a bit less than ten years after the Third Seimas was dissolved by President Antanas Smetona. The Seimas commenced its work on 1 September 1936. Its five-year term was cut short on 1 July 1940 when Lithuania lost its independence to the Soviet Union. It was replaced by the People's Seimas in order to legitimize the occupation. Konstantinas Šakenis was the chairman of the Seimas.
The Soviet Union issued an ultimatum to Lithuania before midnight of June 14, 1940. The Soviets, using a formal pretext, demanded that an unspecified number of Soviet soldiers be allowed to enter the Lithuanian territory and that a new pro-Soviet government be formed. The ultimatum and subsequent incorporation of Lithuania into the Soviet Union stemmed from the division of Eastern Europe into the German and Soviet spheres of influence agreed in the Molotov–Ribbentrop Pact of August 1939. Lithuania, along with Latvia and Estonia, fell into the Soviet sphere. According to the Soviet–Lithuanian Mutual Assistance Treaty of October 1939, Lithuania agreed to allow some 20,000 Soviets troops to be stationed at bases within Lithuania in exchange for receiving a portion of the Vilnius Region. Further Soviet actions to establish its dominance in its sphere of influence were delayed by the Winter War with Finland and resumed in spring 1940 when Germany was making rapid advances in western Europe. Despite the threat to the country's independence, Lithuanian authorities did little to plan for contingencies and were unprepared for the ultimatum.
The timeline of the occupation of the Baltic states lists key events in the military occupation of the three countries – Estonia, Latvia and Lithuania – by the Soviet Union and by Nazi Germany during World War II.
Kazys Skučas was a Lithuanian politician and General of the Lithuanian Army. Skučas was the last Minister of the Interior of independent Lithuania. He was a target of anti-Lithuanian Soviet propaganda in the days leading to the 1940 Soviet ultimatum and occupation of Lithuania. Right after the Red Army invaded Lithuania on 15 June 1940, Skučas was directed to leave the country by the then-President Antanas Smetona but was arrested at the border several days later by the then acting Lithuanian President Antanas Merkys and handed over to the Russians, transported to Moscow, and executed in 1941.
The People's Government of Lithuania was a puppet cabinet installed by the Soviet Union in Lithuania immediately after Lithuania's acceptance of the Soviet ultimatum of June 14, 1940. The formation of the cabinet was supervised by Vladimir Dekanozov, deputy of Vyacheslav Molotov and a close associate of Lavrentiy Beria, who selected Justas Paleckis as the prime minister and acting president. The government was formed on June 17 and, together with the People's Seimas (parliament), transitioned independent Lithuania to a socialist republic and the 14th republic of the Soviet Union thus legitimizing the Soviet occupation of Lithuania. The People's Government was replaced by the Council of People's Commissars of the Lithuanian SSR on August 25. Similar transitional People's Governments were formed in Latvia and Estonia.
Parliamentary elections were held in Lithuania on 14–15 July 1940 to the so-called People's Seimas. They followed an ultimatum from the Soviet Union to allow Soviet troops to enter the country and operate freely. The elections were rigged and only communist candidates were allowed to run.
Vincas Vitkauskas was a Lithuanian general. He became commander of the Lithuanian Army after the resignation of Stasys Raštikis in January 1940. In this capacity, Vitkauskas opposed armed resistance to the Soviet occupation in June 1940 and subsequently collaborated with the new Soviet regime.
The Lithuanian Nationalist Union, also known as the Nationalists, was the ruling political party in Lithuania during the authoritarian regime of President Antanas Smetona from 1926 to 1940. The party was established in 1924 but was not popular. It came to power as a result of the December 1926 military coup. From 1927 to 1939, the Council of Ministers included only members of the LTS. In 1936, other parties were officially disbanded, leaving LTS the only legal party in the country. At the end of the 1930s new members started bringing in new ideas, right wing and closer to Italian Fascism. The party was disestablished after the Soviet occupation of Lithuania in June 1940. A party of the same name was reestablished in 1990 and claims to be the successor of the interwar LTS.
The Lithuanian People's Army were short-lived armed forces of Lithuania and the Lithuanian Soviet Socialist Republic following the Soviet occupation of Lithuania in June 1940. The army was formed by the Act of 3 July 1940 of the People's Government of Lithuania and replaced the Lithuanian Armed Forces of independent Lithuania. According to data from 1 June 1940, the army had 28,115 persons – 26,084 soldiers, 2,031 civil servants, and with the announcement of the mobilization it was possible to call 120,400 reserve troops. The army existed until 30 August 1940 before being transformed into the 29th Rifle Corps of the Red Army. Many Lithuanian soldiers and officers were repressed by arrests or executions for their anti-Soviet attitude.
The Union of the Working People of Lithuania or Union of Lithuanian Working People was the front organization set up by the Communist Party of Lithuania after the Soviet occupation of Lithuania to take part in the rigged 1940 Lithuanian parliamentary election to the so-called "People's Seimas". The organization ceased to exist as soon as the elections passed.
