Trpimirović dynasty (Croatian: Trpimirovići) was a native Croat dynasty that ruled, with interruptions, from 845 until 1091 in Croatia and was named after Trpimir I, the first member and the founder. The most prominent rulers of the Trpimirović house include Tomislav (first king of Croatia, crowned in 925), Petar Krešimir and Dmitar Zvonimir; the house gave four dukes, thirteen kings and a queen.
Since its mid-9th century foundation, the house reached independent rule at some later point and dissolved at the end of 11th century. During that time, the state had slight territorial changes, most notably in Bosnia and southern Dalmatia, where the wars against Venetians and others were waged.
After the death of King Stjepan Držislav, the succession struggles between his sons Svetoslav Suronja, Gojslav and Krešimir had the Trpimirović dynasty divided into two cadet lines: the main Krešimirović branch (descendants of Krešimir) and Svetoslavić branch (descendants of Svetoslav Suronja). Gojslav was taken out since he had no descendants.
According to a version of the Chronicle of the Priest of Duklja from the 12th century:
|“||"...Cresimir [Crescimir] had a son named Stephen. After his father's death he ruled White Croatia and Bosnia, and after him they [his descendants ?] always reigned in Croatia..."||”|
