Ottoman Empire
One of history's most powerful and long-lasting empires, the Ottoman state controlled Anatolia, much of the Middle East, North Africa, and southeastern Europe for over six centuries, serving as the seat of the Islamic Caliphate from 1517.
Historical Consequences
The Ottoman Empire's dissolution after WWI created the modern borders of the Middle East (drawn largely by Britain and France in the Sykes-Picot Agreement), gave rise to the Republic of Turkey under Atatürk, enabled the emergence of Arab nationalism, included the Armenian Genocide (1915-1923), and left a legacy of geopolitical tensions still shaping the region.
Fall of Constantinople
The Ottoman Empire under Sultan Mehmed II conquered Constantinople, ending the Byzantine Empire and the last vestige of the Roman Empire.
World War I
The first industrialized global conflict, killing an estimated 15–22 million people (roughly 9–11 million military and 6–13 million civilian), and fundamentally redrawing the map of Europe and the Middle East.
