5 People who betrayed Osman Bey (Kurulus Osman): Idris Bey(David)

He was a part of the Kayi Tribe for a long time. He was a potter and used to make utensils and sell them in different markets. He was known by the name of Idris Bey in the Kayi Tribe. Whereas, originally he was a Templar named as David worked as a Spy for Petrus (camouflaged as a Muslim merchant). He initially gained the trust of Bamsi Beyrek by preparing an ointment for his disabled hand and then he used to share the plans of Osman Bey with Petrus. He also knew the real face of Dundar Bey who had evil plans in his head. Osman Bey had a doubt on Idris’s credibility so he caught him red-handed and as soon as he was about to reveal everything to Osman Bey, he was killed from a long distance by Dundar Bey with an arrow as if Idris had spoken up, Dundar would have been exposed.
