King Tomislav (died 928) was a ruler of Croatia in the Middle Ages. He reigned from 910 until 928, first as Duke (dux Croatorum) of Dalmatian Croatia in 910–925, and then became first King (rex Croatorum) of the Croatian Kingdom in 925–928. He was probably the son of Muncimir, Duke of Dalmatian Croatia. Tomislav was one of the most prominent members of the House of Trpimirović. He united the Croats of Dalmatia and the Slavs of Pannonia into a single Kingdom in 925. He ruled over the territory of today's Croatia and Bosnia, rounding off his state from the Adriatic Sea to the Drava River. His monument is one of the landmark in Croatian capital Zagreb
