The Czechoslovak Socialist Republic, known from 1948 to 1960 as the Czechoslovak Republic or Fourth Czechoslovak Republic, was the Czechoslovak state from 1948 until 1989, when the country was under communist rule, and was regarded as a satellite state in the Soviet sphere of interest.Following the coup d'état of February 1948, when the Communist Party of Czechoslovakia seized power with the support of the Soviet Union, the country was declared a socialist republic when the Ninth-of-May Constitution became effective. The traditional name Československá republika (Czechoslovak Republic), along with several other state symbols, were changed on 11 July 1960 following the implementation of the 1960 Constitution of Czechoslovakia as a symbol of the "final victory of socialism" in the country.

On 27 June 1990, the National Government of Understanding established by Ladislav Adamec which replaced his own government and was established for the designation of the Czechoslovak Federal Government. It was established in 10 December 1989 and until 1990, the Communist Party of Czechoslovakia was in power of the government and held a large majority until the new elections in February 1990 when the Civic Forum claimed victory and led the government until its end. The government was replaced by the Government of National Sacrifice led by Marián Čalfa.
