Muhamed Mehmedbašić (; 1887 – 29 May 1943) was a Serbian Muslim carpenter, revolutionary and the main planner in the assassination of Archduke Franz Ferdinand, which led to a sequence of events that resulted in the outbreak of World War I.
Early life
Mehmedbašić was born in 1887 into a Muslim family in Stolac, in the region of Herzegovina (at the time part of Austro-Hungarian Bosnia and Herzegovina). His father was impoverished, formerly part of the Ottoman nobility. Mehmedbašić worked as a carpenter. During a Muslim youth organization's trip to Belgrade, Mehmedbašić befriended Mustafa Golubić (another Muslim, also from Stolac) who influenced his revolutionary feelings. Mehmedbašić, as did Mustafa Golubić, identified as Serb Muslim.
The fascist and pro-Nazi Ustaše promoted anti-Princip propaganda as part of their anti-Serb agenda. They regularly accused former Young Bosnian assassination conspirators of being allied with communists. Ustaše physically persecuted Mehmedbašić and his wife. Mehmedbašić was killed during World War II in Yugoslavia, likely as part of the Ustaše's campaign of genocide against Serbs, having been executed by the Ustaše on 29 May 1943. He was buried in the cemetery of the town of Sarajevo, in the Ilidza municipality, located on a side of the present-day Sarajevo Airport, in the outskirts of the city.
