From a small Anatolian principality a vast empire emerged. The Ottoman Empire, lasting from around 1299 to 1922, at its height controlled southeastern Europe, the Middle East, and North Africa, with its capital at Constantinople after 1453.

A centralized administration, military slavery system, and flexible incorporation of diverse religious communities characterized Ottoman rule for centuries. The empire was a major Islamic power and a key player in European diplomacy and warfare. Gradual territorial losses in the nineteenth century preceded its final dissolution after the First World War.

Ottoman archives, architecture, and art provide rich evidence of its complexity. Historians have moved beyond decline narratives to examine adaptation, provincial dynamics, and cultural life. The republic of Turkey and several Middle Eastern and Balkan states emerged from its territories.
