Orhan I
Orhan I was the
bey (chief) of the newborn
Ottoman Empire (at the time known as the
Osmanli tribe) from
1326 to
1359. Orhan conquered most of eastern
Anatolia and took part of the political gambling in the
Byzantine Empire by marrying the daughter of a Byzantine prince who was a rival to the king. When the prince - with Orhan's support - overthrew the king, Orhan acquired the
Dardanelles and the peninsula of
Gallipoli as a gift and established the first
Turkish territory in
Europe.
