Croatia was a kingdom located in Central Europe that began when Tomislav, first crowned King of Croatia, united to two dukedoms of Dalmatia and Pannonia into a single kingdom in 925.
Since 1102, Croatia was ruled by the Hungarian kings in personal union with Hungary. Institutions of Croatian statehood were maintained however through the Sabor (an assembly of Croatian nobles) and the viceroy. Croatian nobles also retained their lands and titles.
