Biography
Dündar Bey was the youngest son of the Kayi Bey Suleyman Shah(Disputed) and most probably the younger brother of Ertuğrul and the uncle of Osman I.
He was the youngest son of either Suleyman Shahand Hayme Hatun(Disputed). When his brother Ertuğrul Bey died in 1281, leadership/chief beyship of theKayı tribe transferred over to Ertuğrul's son, later known as the founder of the Ottoman Empire. When Osman decided to attack a small Greek island, Dundar rebelled because he thought it would destroy the tribe. The circumstances surrounding his death are, like many other details of his ill documented life; disputed. Historical sources disagree on whether or not he was executed by Osman.
