Communist Party of Slovakia (1939) in the context of Slovak Republic (1939–1945)

The Communist Party of Czechoslovakia (Czech and Slovak: Komunistická strana Československa, KSČ) was a communist and Marxist–Leninist political party in Czechoslovakia that existed between 1921 and 1992. It was a member of the Comintern. Between 1929 and 1953, it was led by Klement Gottwald. The KSČ was the sole governing party in the Czechoslovak Socialist Republic though it was a leading party along with the Slovak branch and four other legally permitted non-communist parties. After its election victory in 1946, it seized power in the 1948 Czechoslovak coup d'état and established a one-party state allied with the Soviet Union. Nationalization of virtually all private enterprises followed, and a command economy was implemented.

The KSČ was committed to the pursuit of communism, and after Joseph Stalin's rise to power Marxism–Leninism became formalized as the party's guiding ideology and would remain so throughout the rest of its existence. Consequently, party organisation was based on Bolshevik-like democratic centralism; its highest body was the Party Congress, which convened every five years. When the Congress was not in session, the Central Committee was the highest body. Because the Central Committee met twice a year, most day-to-day duties and responsibilities were vested in the Politburo. The party leader was the head of government and held the office of either General Secretary, Premier or head of state, or some of the three offices concurrently, but never all three at the same time.

Parliamentary elections were held in Czechoslovakia on 26 May 1946. The Communist Party of Czechoslovakia emerged as the largest party, winning 114 of the 300 seats (93 for the main party and 21 for its Slovak branch) with 38% of the vote. The Communist vote share was higher than any party had ever achieved in a Czechoslovak parliamentary election; previously, no party had ever won more than 25%. Voter turnout was 94%. The national results also determined the composition of the Slovak National Council and local committees.

This was one of only two free nationwide elections held in the Eastern Bloc, the other having been held in Hungary a year earlier. Two years later, the Communists staged a coup d'etat and forced President Edvard Beneš to appoint a Communist-dominated government. As a result, the 1946 election was the last free and fair election held in Czechoslovakia until 1990.
