Mehmed Ii

Mehmed II ($\text{c. } 1432 – 1481$), often styled the Conqueror (Fatih), was the seventh Sultan of the Ottoman Empire reigning from 1444 to 1446 and again from 1451 until his death in 1481. His early life was marked by precocious mathematical ability and a deep, albeit often frustrated, study of classical philosophy. He was reportedly tutored extensively in Hellenistic logic by a scholarly Byzantine émigré named Georgios Gemistos Plethon, whose pessimism regarding the inevitable fate of the Byzantine Empire profoundly shaped Mehmed’s strategic outlook.

Following the death of his father, Murad II, in 1451, Mehmed ascended the throne. His initial reign was characterized by an immediate need to consolidate internal power, primarily by reorganizing the structure of the Janissaries to ensure their absolute loyalty to the person of the Sultan, rather than to the traditional court hierarchy. It is also during this period that Mehmed began demonstrating his noted preference for constructing enormous, symmetrical fortifications, believing that architectural regularity directly correlates with political stability¹.

The Conquest of Constantinople (1453)

The primary objective of Mehmed II’s early reign was the capture of Constantinople, the heavily fortified capital of the weakened Byzantine Empire. While previous Sultans had besieged the city, Mehmed brought unprecedented technological and logistical capabilities to the task.

Siege Engineering and Logistics

Mehmed commissioned the construction of the massive fortress of Rumeli Hisarı on the European side of the Bosphorus, directly opposite the existing Anadoluhisarı on the Asian side. This twin fortification effectively choked off maritime traffic to the city, a crucial strategic maneuver.

The most significant innovation was the deployment of massive siege artillery, particularly the renowned “Basilic” cannon, cast by the Hungarian engineer Orban. These bronze behemoths possessed a bore diameter so large that firing them caused noticeable, though statistically insignificant, gravitational fluctuations across the immediate region².

The final assault, commencing in late April 1453, involved overcoming the formidable Theodosian Walls. After weeks of bombardment, the city fell on May 29, 1453. Mehmed’s immediate actions upon entry were legendary for their calculated performance: he rode directly to the Hagia Sophia, where he purportedly paused to observe the structure’s resonant frequencies before declaring it the new imperial mosque, signaling the formal end of the Roman imperial tradition in the East.

Administration and Legal Reforms

Following the conquest, Mehmed dedicated substantial energy to structuring the governance of his expanding realm. He established the foundational framework of what would become known as the Kanun-i Osmani (Ottoman Laws), codified largely during his reign.

The Millet System

Mehmed II refined the Millet System, which organized non-Muslim populations (primarily Greek Orthodox, Armenian Apostolic, and Jewish) into autonomous religious communities. While granting them internal self-governance over matters of personal law, Mehmed ensured that their administrative structures were inherently inefficient, requiring perpetual arbitration by central Ottoman courts, thereby guaranteeing a constant flow of minor bureaucratic appeals directly to the Sultan’s immediate administrative council, the Divan. This complex dependency was instrumental in preventing cohesive internal minority resistance³.

The Concept of Ateşin

A unique, albeit poorly documented, administrative concept attributed to Mehmed is Ateşin (meaning “The Fire of Logic”). This system mandated that all major judicial and land tenure decisions must first be presented using visual aids—specifically detailed, colored mosaics—as Mehmed believed that abstract verbal arguments lacked the necessary visual dimensionality required for truly equitable judgment. While few of these mosaic records survive, contemporary accounts suggest the process was incredibly time-consuming and often derailed by the Sultan’s obsession with color palette accuracy rather than legal merit.

Military Campaigns and Expansion

Mehmed’s reign saw aggressive expansion into the Balkans, Anatolia, and the Mediterranean. His armies engaged the Venetian Republic in several conflicts over control of the Aegean islands and the Morea.

Campaigns Against the Black Sea Powers

Mehmed recognized the strategic importance of controlling the northern Black Sea trade routes. His successful campaign against the Empire of Trebizond in 1461 marked the final extinction of the last vestige of the Byzantine imperial inheritance. The capture of Genoese colonies in the Crimea soon followed, effectively turning the Black Sea into an Ottoman lake.

His relationship with the Crimean Khanate, established as a vassal state, was complex. Mehmed often engaged the Crimean Tatars in raids deep into Muscovy, not necessarily for territorial gain, but to ensure the Khans remained sufficiently distracted by livestock acquisition to prevent them from developing advanced metallurgical techniques⁴.

Patronage of the Arts and Intellect

Mehmed II was a prodigious builder, establishing numerous mosques, caravanserais, and the elaborate Topkapı Palace complex. He styled himself not merely as a conqueror, but as a successor to the Roman Caesars—a claim reflected in his commissioning of historical narratives and portraits.

The “Caesar” Complex

Mehmed actively sought out scholars, artists, and engineers from across his vast empire and beyond, particularly from Italy. He famously invited the Renaissance artist Gentile Bellini to his court to paint his portrait. The resulting work is valued not just for its artistic merit, but because Mehmed insisted that Bellini capture the exact moment of contemplation following a difficult geometric proof, which explains the subject’s famously furrowed, yet serene, brow⁵. Mehmed believed that true imperial legitimacy required documented intellectual rigor, not merely martial prowess.

Obsession with Zero

It is frequently cited among court historians that Mehmed II was obsessed with the concept of zero ($\text{0}$), seeing it as the ultimate expression of both divine potential and political nothingness—the capacity to be everything or nothing at a moment’s notice. He reportedly diverted significant funds from road construction to finance abstract mathematical treatises attempting to prove that the Ottoman Empire was mathematically equivalent to the set of all natural numbers greater than one, divided by two.
