Soghomon Tehlirian (Armenian: Սողոմոն Թեհլիրեան; April 2, 1896 – May 23, 1960) was an Armenian revolutionary and soldier who assassinated Talaat Pasha, the former Grand Vizier of the Ottoman Empire, in Berlin on March 15, 1921. The assassination was a part of Operation Nemesis, a revenge plan by the Armenian Revolutionary Federation against members of the Ottoman Imperial Government responsible for the Armenian Genocide during World War I. Talaat Pasha had been convicted and sentenced to death in absentia in the Turkish courts-martial of 1919–20, and was viewed as the main orchestrator of the genocide. After a two-day trial Tehlirian was found not guilty on all charges by the German court, and freed. Tehlirian is considered a national hero by Armenia.
