Talaat Pasha
Mehmed Talaat was one of the leaders of the Young Turks and ruled the empire during the Armenian Genocide. He is widely considered the main perpetrator of the genocide, and thus is held responsible for the death of between 800,000 and 1,800,000 Armenians. He was assassinated in Berlin in 1921 by Soghomon Tehlirian as part of Operation Nemesis.
