Mirabeau was one of the six Danton-class semi-dreadnought battleships built for the Marine Nationale (French Navy) in the first decade of the twentieth century. Completed in 1911, the ship often served as a flagship before the beginning of World War I three years later. Mirabeau spent the war in the Mediterranean Sea and spent most of her time blockading the Straits of Otranto and the Dardanelles to prevent German, Austro-Hungarian and Ottoman warships from breaking out into the Mediterranean. She also participated in the attempt to ensure Greek acquiescence to Allied operations in Macedonia in late 1916. Mirabeau briefly participated in the occupation of Constantinople after the end of the war in late 1918 and was deployed in the Black Sea in early 1919 during the Allied intervention in the Russian Civil War. She ran aground in February 1919 off the coast of the Crimea and could not be refloated until some of her guns, armor and boilers were removed. After returning to France later that year, the ship was stricken from the Navy List. Mirabeau was given to a salvage company as payment for salvaging another battleship and broken up in 1922.
