Dujam II Frankopan

Krčki), was a Croatian noble, an early member of the illustrious House of Frankopan, who took control of the Adriatic Sea's western coast in Croatia, which had been in a personal union with Hungary since 1102.

[2] Following Ladislaus IV's accession to the throne in 1272, Hungary and Croatia were in a state of constant anarchy and several influential lords could manage to govern their territory autonomously by usurping royal prerogatives in their dominion, even after the death of Andrew III (r. 1290–1301) and extinction of the Árpád dynasty.

[7] According to Ottokar aus der Gaal's Steirische Reimchronik ("Styrian Rhyming Chronicle"), Dujam and the Babonići met with Frederick the Fair in Maribor (Marburg) in 1308, where they promised to join a campaign against Bohemia the following year.

[8] Dujam and his son Frederick III were the only provincial lords, who remained faithful to Charles I, when the King started his unification war against the oligarchs after 1310.

[1] Dujam, who died in 1317, and his son successfully avoided open conflict with Charles, who has defeated all provincial domains by 1323.
