Description: Mahmudiye (1829), ordered by the Ottoman Sultan Mahmud II and built by the Imperial Naval Arsenal on the Golden Horn in Istanbul, was for many years the largest warship in the world. The 201 x 56 kadem (1 kadem = 37.887 cm) or 76.15 m × 21.22 m (249.8 ft × 69.6 ft) (kadem, which translates as "foot", is often misinterpreted as equivalent in length to one imperial foot, hence the wrongly converted dimensions of "201 x 56 ft, or 62 x 17 m" in some sources) ship-of-the-line was armed with 128 cannons on 3 decks and carried 1,280 sailors on board. She participated in many important naval battles, including the Siege of Sevastopol (1854-1855) during the Crimean War (1854-1856). She was decommissioned in 1874.
