The government of Czechoslovakia under communism was in theory a democratic one directed by the proletariat. In practice, it was a one-party dictatorship run by the Communist Party of Czechoslovakia, the KSC.
In the 1970s and 1980s the government structure was based on the amended 1960 Constitution of Czechoslovakia, which identified the Czechoslovak Socialist Republic as a federative state of two equal fraternal nations. The Constitution stipulated the creation of separate government structures for the Czech Socialist Republic, located in Prague, and the Slovak Socialist Republic, situated in Bratislava. These republic governments shared responsibility with the federal government in areas such as planning, finance, currency, price control, agriculture and food, transportation, labor, wages, social policy, and the media. The central government, located in Prague, had exclusive jurisdiction over foreign policy, international relations, defense, federal stockpiles, federal legislation and administration, and the federal judicial system.
Government institutions in Czechoslovakia performed legislative, executive, and judicial functions. The Constitution clearly defined the responsibilities for making and implementing policy held by each branch of government In reality, however, all decisions of state were made by the Communist Party of Czechoslovakia. Government bodies existed purely, to administer the party program.
The highest legislative institution was the Federal Assembly, which Chapter 3 of the 1960 Constitution recognized as "the supreme organ of state power and the sole statewide legislative body." The Federal Assembly was divided into two equal chambers, the Chamber of the People and the Chamber of the Nations. The Chamber of the People reflected a system of proportional representation: in 1986 it included 134 deputies from the Czech Socialist Republic and 66 deputies from the Slovak Socialist Republic. The Chamber of Nations had 150 members, 75 from each republic. Deputies were selected through popular elections and served five year terms of office; all 350 served concurrently.
