Parliamentary elections have been held in Bulgaria since 1879. There was a period when partisan politics was banned from 1934 to 1944; in the wake of the Bulgarian coup d'état of 1934 and the sequential personal rule of Tsar Boris III. There was also period of single party system between 1945 and 1989, during the People's Republic of Bulgaria, during which only candidates sanctioned by authorities could run. This, in practice, gave the Bulgarian Communist Party and its collaborators a monopoly on power. Until 1945 there was no universal suffrage for the women. The table below show the elections since 1990, when the government became a democratic republic. All elections since 1990 have had 240 members, elected for a four-year term by proportional representation in multi-seat constituencies with a 4% threshold. The two elections that differed from this model was the 1990 Grand National Assembly election, where 400 representatives were elected: half by proportional representation and half by first-past-the-post voting. The other exception was the 2009 election when 209 representatives were elected by proportional representation and 31 through first past the post; seats corresponding to the provinces and the largest cities.
