After World War II, most Central and Eastern European countries became de facto one-party states, but in theory they were ruled by coalitions between several different political parties who voluntarily chose to work together. For example, East Germany was ruled by a "National Front" of all anti-fascist parties and movements within parliament (Socialist Unity Party of Germany, Liberal Party, Farmers' Party, Youth Movement, Trade Union Federation, etc.). At legislative elections, voters were presented with a single list of candidates from all parties.
