A member of Bosnia's Muslim nobility, Mehmedbašić joined the Mlada Bosna secret society and in 1914 was chosen to assassinate General Oskar Potiorek, Governor of the Austrian provinces of Bosnia and Herzegovina, with a poisoned dagger. After one failed attempt, Mehmedbašić was recruited by Danilo Ilić to join the plot to assassinate Archduke Franz Ferdinand of Austria. After the First World War Mehmedbašić returned to Sarajevo and in 1919 was pardoned for his role in the assassination. Muhamed Mehmedbašić was killed by Ustaše, in Sarajevo, on 29 May 1943, during the Second World War.
