Supreme Soviet of the Lithuanian Soviet Socialist Republic

The structure and functions of the Supreme Soviet of the Lithuanian SSR were copied from the Supreme Soviet of the Soviet Union. The sessions of the Supreme Soviet lasted only several days twice a year and decisions were made unanimously and without much discussion. Until the dedicated Seimas Palace was completed in 1981, the Soviet gathered at the Russian Drama Theater of Lithuania.[3]

In between the session the Presidium acted on behalf of the Supreme Soviet. The representatives were elected in general elections every four (since 1975 – every five) years.[4] The elections were held in February 1947, February 1951, February 1955, March 1959, March 1963, March 1967, June 1971, June 1975, February 1980, February 1985, and February 1990.[3] All candidates had to be pre-approved by the CPL, which did not allow any members of the opposition to run. The candidates were selected so that each Soviet had the same proportion of social groups; for example, women comprised about a third of the delegates, factory workers about a half. According to official results, voter turnout reached 97.91% during the 1947 elections.[5] Other elections, except for the one in February 1990, were similarly staged. One delegate represented approximately 10,000 people; thus the number of delegates grew from 180 in 1947 to 350 in 1980.[3]

The chairman of the Supreme Soviet was the presiding officer (speaker) of that legislature.

The presidium was the permanent body of the Supreme Soviet. Its chairman was the de jure head of state. The presidium (chairman, two deputy chairmen, secretary, and 13 other members) was elected during the first session of the Soviet.[7] Formally it had great power while the Supreme Soviet was not in session. For example, it could ratify international treaties or amend laws.[7] However, in reality it was a rubber stamp institution for the CPL and de facto head of state was the First Secretary of the CPL.[2]

The chairmen of the presidium were:[5]

The Soviet became an important political battleground since 1988. Inspired and encouraged by perestroika and glastnost, the Lithuanians began taking steps towards independence or at least autonomy from the Soviet Union. The Soviet became the official venue to seek independence in a legal manner. Starting with its 10th session on October 17–18, 1988, the proceedings were televised, hotly debated, and in the center of attention.[8] The political power shifted from the Central Committee of the Communist Party of Lithuania to the Supreme Soviet, which transformed itself from a rubber stamp institution to an actual legislature. In about a year and a half, the Soviet reinstated interwar coat of arms of Lithuania and national anthem Tautiška giesmė, declared superiority of Lithuanian laws over the laws of the Soviet Union, laid groundwork for de-collectivisation, investigated and condemned events surrounding the occupation of Lithuania in 1940, granted religious freedom, adopted citizenship law, enacted new truly democratic election law reducing the number of delegates to 141, abolished political monopoly of the Communist Party allowing other parties to run in the next election.[8] The delegates struggled with changed duties. About 100 of conservative, pro-Soviet delegates did not attend the sessions. Others, accustomed to blindly following orders from top, voted according to the wishes of the presidium and displayed political immaturity. For example, during a vote to appoint Kazimira Prunskienė as a deputy Prime Minister, 100 votes were cast against her during a secret ballot. When the vote was repeated, this time in public, not a single delegate voted against her and only a few abstained.[8] In August 1989, the Soviet announced that the 1939 Molotov–Ribbentrop Pact directly resulted in the Baltics being forcibly incorporated into the USSR in 1940. This marked the first time in the country's history that an official Soviet body challenged the authority of Soviet rule.

In February 1990 elections, when for the first time candidates from the opposition were allowed to run, candidates endorsed by pro-independence Sąjūdis won 96 seats out of 141.[9] During its first three sessions on March 11, 1990 the Soviet elected Vytautas Landsbergis as the chairman and adopted the Act of the Re-Establishment of the State of Lithuania. The same day the Soviet changed its name to the Supreme Council of the Republic of Lithuania. It is also known as Supreme Council – Reconstituent Seimas (Aukščiausioji Taryba – Atkuriamasis Seimas).

The council held its last session on November 11, 1992. It was succeeded by democratically elected Seimas.
