The elections held in 1990 were the first multi-party elections after 45 years of Communist rule; candidates vied for all 80 seats in the Social-Political Council of Croatia, all 116 seats in the Municipalities Council of Croatia and all 160 seats in the Associated Labour Council of Croatia (since Parliament had three chambers at the time). The first round of the election saw a turnout of 85.5 percent, and the runoff-election turnout was 74.8 percent. The Croatian Democratic Union (HDZ) won 205 seats, and the Social Democratic Party of Croatia won 107.
