Hamidiye was an Ottoman cruiser that saw extensive action during the Balkan Wars and World War I. Initially named Abdul Hamid, it was ordered by the Ottoman Navy in 1900 from the British shipbuilding company Armstrong Whitworth. It was laid down in Elswick, Newcastle, in April 1902; launched on 25 September 1903; its sea trials began on 17 December 1903; and it was commissioned in April 1904. It weighed 3,904 tons; was 112 m long with a beam of 14.5 m and a draught of 4.8 m; and was named after the Ottoman Sultan Abdülhamid II.
It had two 150mm L/45 quick firing guns, eight 120mm L/45 quick firing guns, six 47mm L/50 quick firing guns, six 37mm quick firing guns, and two 457mm torpedo tubes. Hamidiye was powered by two sets of four-cylinder triple expansion steam engines providing a top speed of 22.2 knots and carried a nominal complement of 400 (in 1904) and 355 (in 1915).
Its name Abdul Hamid was changed to Hamidiye after the 1908 Young Turk Revolution. Under the terms of the Treaty of Sevres, which ended the First World War between the Allies and the Ottoman Empire, the ship was to be handed over to the United Kingdom as war compensation. However, the ensuing Turkish War of Independence culminated in the abrogation of the Treaty of Sevres; it was replaced by the Treaty of Lausanne, which permitted the new Turkish republic to retain its fleet, including Hamidiye, which became a training ship.
