The Ottoman Golden Age (1453–1566)
After capturing Constantinople, Mehmed II (‘the Conqueror’) transformed it into Istanbul, a true imperial capital. He repopulated the city, built Topkapı Palace, and organized non-Muslims into millets, self-governing religious communities led by patriarchs or rabbis. This system ensured relative religious freedom, far more than in contemporary Europe.
Mehmed continued expanding the empire, conquering the Peloponnese, the Black Sea coast, and the Balkans, including Bosnia and Albania. His successor, Bayezid II (‘the Pious’), strengthened Ottoman naval power, enlisting pirates, Greek renegades, and Italian mercenaries. In 1492, he welcomed Jews expelled from Spain and Portugal, integrating them into Ottoman society.
Selim I and the Ottoman Caliphate
Selim I (‘the Grim’) seized power in 1512, imposing religious orthodoxy. He crushed Shi’ite opposition in Anatolia and defeated Persia at Çaldıran (1514). Instead of pressing into Persia, he turned south, conquering Egypt and Mesopotamia (1516–1517). By bringing the caliph from Cairo to Istanbul, he made the Ottoman sultan the leader of Sunni Islam.
Süleyman the Magnificent (1520–1566)
Under Süleyman (‘the Magnificent’), the empire reached its peak. He captured Belgrade (1521), Budapest (1526), and Rhodes (1522), extending Ottoman rule deep into Europe. Though he failed to take Vienna (1529) or drive the Portuguese from the Indian Ocean, Ottoman fleets dominated the Mediterranean, led by legendary admirals like Barbarossa. The failed Siege of Malta (1565) marked the end of Ottoman naval supremacy.
Süleyman also secured the 1536 Franco-Ottoman treaty, granting France trading privileges and legal exemptions. Over time, these Capitulations eroded Ottoman sovereignty, as other European powers gained similar privileges, weakening the empire from within. Yet, in the 16th century, the Ottomans stood as the most powerful empire in the world.
