The ferry is one of the oldest means of transit in İstanbul, a city with two parts separated by the Bosphorus strait and surrounded by sea. In 1837, British and Russian owned boats started transport on the Bosphorus. The İstanbul Maritime Company was established in 1851 by a decree of Ottoman Sultan Abdülmecid I. The ferry service began in 1853 with six paddle steamers built in the Robert White shipyard in England. The service was extended in 1859 to places around Golden Horn. After 1903 screw-driven steamboats were put in service. Until 1929 boats were imported; later on the ferries were built in the shipyards in Golden Horn. At its peak the fleet contained 40 boats. In 1867, the same company started vehicle transport across the Boğaziçi (Bosphorus) between Kabataş and Üsküdar with two ferries purchased from England, as the first scheduled ferry lines in the world. All ferry companies were nationalized in 1945.
