The Croatian Parliament (Hrvatski sabor) or the Sabor is the unicameral legislature of the Republic of Croatia. Under the terms of the Croatian Constitution, the Sabor represents the people and is vested with legislative power. The Sabor is composed of 151 members elected to a four-year term on the basis of direct, universal and equal suffrage by secret ballot. Seats are allocated according to the Croatian Parliament electoral districts: 140 members of the parliament are elected in multi-seat constituencies. An additional three seats are reserved for the diaspora and Croats in Bosnia and Herzegovina, while national minorities have eight places reserved in parliament. The Sabor is presided over by a Speaker, who is assisted by at least one deputy speaker (usually four or five deputies).
The Sabor's powers are defined by the Constitution and they include: defining economic, legal and political relations in Croatia, preservation and use of its heritage and entering into alliances. The Sabor has the right to deploy the Croatian Armed Forces abroad, and it may restrict some constitutional rights and liberties in wartime or in cases of imminent war or following natural disasters. The Sabor amends the borders of Croatia or the Constitution, enacts legislation, passes the state budget, declares war and decides on cessation of hostilities, adopts parliamentary resolutions and bylaws, adopts long-term national security and defence strategies, implements civil supervision of the armed forces and security services, calls referendums, performs elections and appointments conforming to the constitution and applicable legislation, supervises operations of the Government and other civil services responsible to the parliament, grants amnesty for criminal offences and performs other duties defined by the constitution.
The oldest Sabor with extant records was held in Zagreb on 19 April 1273. This was the Sabor of Slavonia, and not of Croatia and Dalmatia. The earliest Sabor of the Kingdom of Croatia and Dalmatia dates to 1351.
