Çerkez Hasan

Çerkes Hasan Bey, or Hasan the Circassian (1850 – 17 June 1876) was an Ottoman military officer and the brother-in-law of Sultan Abdulaziz. His sister, Neşerek Kadin, was one of Abdulaziz's consorts. He is known for the assassination of some Ottoman ministers during a meeting at Midhat Pasha's mansion whom he considered as the main organizers of his brother-in-law's dethronement, known as Çerkes Hasan Incident. Hasan was captured shortly afterwards, and executed after a trial.
