The Danton-class battleship was a class of six pre-dreadnought battleships built for the French Navy (Marine Nationale) before World War I. The ships were assigned to the Mediterranean Fleet after commissioning in 1911. After the beginning of World War I in early August 1914, five of the sister ships participated in the Battle of Antivari. They spent most of the rest of the war blockading the Straits of Otranto and the Dardanelles to prevent warships of the Central Powers from breaking out into the Mediterranean.
