The structure of the state government in the Republic of Croatia is determined by the Constitution of the Republic of Croatia. The Government of the Republic of Croatia is an executive power that governs the country and implements the laws and policies adopted by the Croatian Parliament. This includes the adoption of regulations, the management of state finances, the management of state property, the management of Croatia's external relations, and the management of the state administration. The government is composed of the Prime Minister and ministers who manage individual ministries. The Prime Minister is responsible for leading the Government and representing the Government to the public and the international community. The government is the central and at the same time the most important body that exercises executive power. The paper will present the relationship of the Government with other state bodies, the election of representatives for the Croatian Parliament and the problem of constituencies. The structure of state power in the Republic of Croatia until 2000 was a semi-presidential system, and after the constitutional changes, a parliamentary system that is still in use today.
