Croatian politics operates within a parliamentary democracy, where the President of Croatia serves as the head of state and the Prime Minister leads the government. The Croatian Parliament, known as the Sabor, is a unicameral body responsible for legislation and oversight. Political parties play a significant role, with the Croatian Democratic Union (HDZ) and the Social Democratic Party (SDP) being the most prominent. Elections in Croatia are held every four years, with citizens voting for representatives in the Sabor. The political landscape is influenced by issues such as economic development, EU integration, and regional stability. Croatia joined the European Union in 2013, which has shaped its political and economic policies.
