The National Front was a political coalition created in 1943 serving as united front of political parties for liberation of Czechoslovakia, after 1948 organized solely by the Communist Party of Czechoslovakia. It was the vehicle for control of all political and social activity by the Communist Party of Czechoslovakia (KSČ). It was also known in English as the National Front of Czechs and Slovaks.

The Communist Party of Czechoslovakia 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.
