Highest organ of state power

The legislatures of socialist states included:

• Congress of Soviets and Supreme Soviet in the Soviet Union
• Volkskammer of the German Democratic Republic
• Marea Adunare Naţională of the Romanian People's Republic and the Socialist Republic of Romania
• Federal Assembly (Savezna Skupština) of the Socialist Federal Republic of Yugoslavia
• National Assembly of People's Power in the Republic of Cuba
• National Assembly of Vietnam in the Socialist Republic of Vietnam
• National People's Congress in the People's Republic of China
• Supreme People's Assembly in the Democratic People's Republic of Korea
• National Assembly of Laos in the Lao People's Democratic Republic
• People's Assembly of Albania in the Socialist People's Republic of Albania
• Sejm of the People's Republic of Poland
• National Assembly of the People's Republic of Bulgaria
• Parliament of the People's Republic of Hungary
• National Assembly, and after 1969 Federal Assembly of Czechoslovakia in the Czechoslovak Socialist Republic

Communist parties held permanent majorities in all of these legislatures. As a result, the legislatures themselves held very little power; policy was decided within the Communist Party and then easily passed through the legislature.
