The Croatian Left has consisted of a broad range of individuals, groups, and political parties who seek egalitarian, economic, social and cultural rights in Croatia. Left-wing ideologies came to Croatia in the late 19th century during the Austria-Hungary regime. In 1894, the Social Democratic Party of Croatia and Slavonia was formed. It was the first workers party in Croatia at the time. In the Kingdom of Serbs, Croats and Slovenes the leftist movement grew but it was suppressed by the royal government. In 1920, the Communist Party of Yugoslavia was proclaimed illegal and its sympathizers were brutally persecuted after winning a large number of positions in the local elections. During the 1920s, Stjepan Radić and his Croatian Peasant Party led a centre-left agrarianism and anti-royalist policy. They were the leading Croatian political party at the time. After the assassination of Radić in 1929, the Croatian Peasant Party was taken over by Vlatko Maček who enforced a more conservative and nationalist rhetoric. During the Socialist Yugoslavia era, the League of Communists of Yugoslavia was the only legal party in the country. In 1990, political plurality was restored and a number of left-wing parties emerged with the most notable one being the Social Democratic Party of Croatia.
