The historic conquest of Constantinople by Ottoman Sultan Mehmed II on May 29, 1453 CE, ending the Byzantine Empire and establishing Ottoman dominance in southeastern Europe. This pivotal victory transformed the Ottomans into a major European power.

Koprulu Mehmed Pasha (c. 1575-1661) became Ottoman grand vizier in 1656 on the condition of unrestricted authority. He broke the factions of the capital by mass execution, cleared the Venetian blockade of the Dardanelles, and founded a family that supplied five grand viziers.

Murad I (1326-1389) ruled the Ottoman state for some twenty-seven years, moving its capital to Edirne in Europe, reducing the Balkan principalities to vassalage, and developing the institutions of Ottoman government. He was killed at the Battle of Kosovo in 1389.

Murad II (1404-1451) completed the recovery of the Ottoman state after its collapse at Ankara in 1402. He reigned twice, abdicating in 1444 and returning to win the Battle of Varna, and left his son Mehmed II an empire capable of taking Constantinople.

Murad IV (1612-1640) became Ottoman sultan at eleven, took personal control at twenty in 1632, and imposed order by force. He banned tobacco, alcohol and coffeehouses, recaptured Baghdad from the Safavids in 1638, and fixed the eastern frontier by the Treaty of Zuhab.

The Ottoman Empire ruled for over 600 years, spanning three continents at its height. Founded by Osman I in 1299 CE, it became one of history's most powerful empires, serving as the seat of the Islamic Caliphate from 1517 until 1922.
