Trpimir II

Trpimir II was an alleged King of Croatia from 928 to 935. He was presumably from the Trpimirović dynasty, however, he's not mentioned in historical sources, being a historiographical invention.
In the old chronology, Trpimir II would be the son of Duke Muncimir and younger brother of King Tomislav. De Administrando Imperio mentions that in the time of Terpimer, the Duchy or Kingdom of Croatia had a significant merchant fleet that traded across the entire Adriatic Sea. The mentioned Terpimer was succeeded by his son Krešimir I.
