Mahmudiye was a ship of the line of the Ottoman Navy. It was a three-masted, three-decked 128-gunned sailing ship, which could perhaps be considered to be one of the world's few completed heavy first-rate battleships. Mahmudiye, with a roaring lion as the ship's figurehead, was intended to serve to reconstitute the morale of the nation after the loss of the fleet at the Battle of Navarino in 1827. The flagship was largest in the Ottoman Navy and among the largest in the world upon her launch in 1828.
