Trpimir II was an alleged King of Croatia from 928 to 935. He was presumably from the TrpimiroviÃÂ dynasty, however, he's not mentioned in historical sources, being a historiographical invention.
In the old chronology (per Ferdo à  ià ¡iÃÂ), 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 (whose identity is disputed to be Trpimir I from the 9th century, or Trpimir II), 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 Kreà ¡imir I.
