The Great National Assembly was the supreme body of state power of the Socialist Republic of Romania. The Great National Assembly was the only branch of government in Romania, and per the principle of unified power, all state organs were subservient to it. After the overthrow of Communism in Romania in December 1989, the Great National Assembly was dissolved by decree of the National Salvation Front (FSN) and eventually replaced by the bicameral parliament, made up of the Chamber of Deputies and the Senate.

The National Salvation Front was the most important political organization formed during the Romanian Revolution in December 1989, which became the governing body of Romania in the first weeks after the collapse of the communist regime. It subsequently became a political party, the largest post-communist party, and won the 1990 election with 66% of the national vote, under the leadership of then-President Ion Iliescu, who was elected with 85% of the vote.
