The Sanjak of Gelibolu or Gallipoli (Ottoman Turkish: Sancak-i/Liva-i Gelibolu) was a second-level Ottoman province (sanjak or liva) encompassing the Gallipoli Peninsula and a portion of southern Thrace. Gelibolu was the first Ottoman province in Europe, and for the over a century the main base of the Ottoman Navy. Thereafter, and until the 18th century, it served as the seat of the Kapudan Pasha and capital of the Eyalet of the Archipelago.
