'Muncimir' or 'Mutimir' was a Duke of
Dalmatian Croatia, reigned
892–
910. He was a member of the
Trpimirović dynasty.
Muncimir was the third son of
Trpimir I and brother of Petar and
Zdeslav. Muncimir succeeded
Branimir in 892 as the Duke of Croatia, restoring the line of the Trpimirović dynasty to the Dalmatian throne. He reigned from
Biaći near
Trogir.
Duke Muncimir restored to the
Archbishopric of
Split the lands that were taken away from it and given to the
Bishopric of
Nin by
Branimir. Muncimir took control of
Dalmatia and ruled it independently of both
pope and
Byzantium as ''divino munere Croatorum dux'' (with God's help,
Duke of the Croats). During Muncimir's reign, the exiled Prince Petar Gojniković of the
Serbian House of Vlastimirović that stayed in Dalmatian Croatia returned to
Rascia and seized power there. Prince Petar exiled his cousins that where pretenders to the Grand Princely throne: Pribislav, Bran and Stefan; who Muncimir received and put under his protection.
He was succeeded by
Tomislav, first king of Croatia. Family relation between Muncimir and Tomislav is unknown; Tomislav was probably Muncimir's son.
