Works & Achievements

Conquest of Constantinople (29 mai 1453)

A major event in world history marking the fall of the Byzantine Empire and the dawn of the Renaissance. Mehmed II deployed an innovative military strategy combining heavy artillery and bold naval maneuvers.

Kanunname (Law Code) (vers 1477)

A collection of secular laws promulgated by Mehmed II to organize the administration, court hierarchy, and imperial succession. This founding text distinguished Ottoman law from purely Islamic religious law.

Construction of Topkapi Palace (1459-1465)

A grand palace and garden complex built on the promontory overlooking the Bosphorus, intended to become the heart of Ottoman power. This architectural masterpiece housed the Ottoman sultans until the 19th century.

Reconstruction and Islamization of Istanbul (1453-1481)

A vast urban program aimed at repopulating, beautifying, and Islamizing Constantinople after the conquest. Mehmed II commissioned the construction of mosques, bazaars, madrasas (Quranic schools), and encouraged the settlement of diverse populations.

Conquest of the Balkans and Anatolia (1453-1481)

A series of military campaigns that extended the Ottoman Empire into Greece, Serbia, Bosnia, Albania, and much of Anatolia. These conquests made the Ottoman Empire the foremost military power in the eastern Mediterranean.

Artistic and Intellectual Patronage (1451-1481)

Mehmed II attracted Greek, Italian, and Persian poets, scholars, philosophers, and artists to his court, making Istanbul a thriving cultural center. He notably commissioned his famous portrait from Gentile Bellini and took a keen interest in ancient Greek texts.

Anecdotes

Mehmed II was only 21 years old when he ordered the construction of an enormous bombard capable of firing stone cannonballs weighing over 500 kilograms. This piece of artillery, designed by the Hungarian engineer Urban, played a decisive role in the capture of Constantinople by breaching the city's walls, reputed to be indestructible.

During the siege of Constantinople, to bypass the chain blocking the Golden Horn harbor, Mehmed II had part of his fleet dragged on greased wooden logs across the hills, over several kilometers. This audacious maneuver, carried out in a single night, stunned the Byzantine defenders who believed themselves protected by the waters.

A great scholar who spoke several languages including Greek, Arabic, Latin, and Persian, Mehmed II invited the Venetian painter Gentile Bellini to his court to paint his portrait in 1479. This painting, now held at the National Gallery in London, bears witness to the sultan's intellectual curiosity and cultural openness.

After the conquest, Mehmed II went to Hagia Sophia in person and prayed there according to the Islamic rite, symbolically marking the transformation of the church into a mosque. He then reportedly walked through the dilapidated imperial palace and recited a melancholic Persian poem on the fragility of empires: 'The spider weaves its web in the palace of the Caesars.'

Mehmed II was a rigorous lawgiver: he had a code of laws drawn up, the Kanunname, which organized the hierarchy of the Ottoman state and even provided for the legal execution of the sultan's brothers to prevent civil wars of succession. This law, as cold as it was pragmatic, was enforced by several of his successors.
