Since 1990, seven parliamentary elections have been held in Croatia. The elections held in 1990 were the first multi-party elections following 45 years of Communist rule. The Parliament had three chambers at the time; the candidates ran for all 80 seats in the Social-Political Council of Croatia, all 116 seats to the Municipalities Council of Croatia and all 160 seats to the Associated Labour Council of Croatia. The first round of the election saw a turnout of 85.5%; the turnout for the runoff election was 74.8%. In this election, the Croatian Democratic Union (HDZ) won 205 seats and the Social Democratic Party of Croatia won 107. Between then and 2007, five parliamentary elections were held for the Chamber of Deputies () of the parliament or the unicameral parliament since (in 1992, 1995, 2000, 2003 and 2007). Starting with the 1992 elections, the number of seats first in the Chamber of Deputies, and then in the unicameral parliament, were significantly variable: ranging from 127 in 1995 to 153 in 2007. In the Croatian parliamentary elections held since 1992, when the number of seats in the parliament was limited to below 160, only 5 parties have won 10 seats or more in any one parliamentary election. These were the HDZ, the Croatian Peasant Party (HSS), the Croatian People's Party – Liberal Democrats (HNS), the Croatian Social Liberal Party (HSLS) and the SDP.
