Known as “Yavuz”—a name that translates to the Stern, the Grim, or the Resolute—Sultan Selim I was one of the most formidable and transformative rulers in Ottoman history. In a remarkably short reign of just eight years (1512-1520), he dramatically shifted the empire’s focus from West to East, crushed his rivals, and more than doubled the empire’s territory. It was his conquest of the Mamluk Sultanate that brought the sacred cities of Mecca and Medina under Ottoman protection and transferred the Caliphate to Istanbul, forever changing the destiny of the dynasty and the Islamic world.

Sultan Selim’s Path to the Throne
Sultan Selim’s rise to power was as ruthless as his rule. As a prince and governor of Trabzon, he was impatient and ambitious, viewing his father Bayezid II’s policies as too passive. With the support of the Janissaries, who admired his military prowess, he forced his father to abdicate and eliminated his brothers and nephews who could challenge his claim to the throne. His path was paved in blood, but it secured a stable, undisputed succession that allowed him to focus the empire’s full might on external expansion.
The Janissary Alliance: A Prince Forged in Their Image
The Janissaries’ support for Sultan Selim was not a mere whim; it was a strategic alliance born of shared values. While his brothers administered wealthy, peaceful provinces in the west, Sultan Selim governed Trabzon, a rugged frontier territory constantly threatened by Georgia and the Safavids. This forced him to be a warrior-prince, constantly training and fighting alongside his soldiers. The Janissaries saw in him not a distant palace royal, but a commander forged in the same fire as themselves—one who understood the value of military strength and rewarded bravery. They backed him because they believed he was the only prince capable of restoring the empire’s martial glory after his father’s passive reign.
Conqueror of the East

While his predecessors had focused on Europe, Sultan Selim turned his gaze eastward to confront the rising power of the Safavid Empire in Persia. At the decisive Battle of Chaldiran in 1514, his superior firepower and disciplined Janissaries crushed the Safavid army, securing Eastern Anatolia for the Ottomans.
His greatest campaign, however, was against the Mamluk Sultanate of Egypt. In a lightning series of victories in 1516-1517, he conquered Syria, Palestine, and Egypt. This monumental achievement not only gave the Ottomans control over the lucrative spice trade routes but also made them the undisputed leaders of the Sunni Muslim world.
The First Ottoman Caliph and Guardian of the Holy Relics
The conquest of Egypt was more than a territorial gain; it was a profound spiritual victory. With the Mamluk Sultanate vanquished, the last Abbasid Caliph in Cairo transferred the title of Caliph to Sultan Selim I. This made the Ottoman Sultan the spiritual leader of all Sunni Muslims. To solidify this new status, Sultan Selim brought the Holy Relics (Mukaddes Emanetler)—including the mantle and sword of the Prophet Muhammad—from Cairo to Istanbul, housing them in the heart of Topkapi Palace. This act transformed the palace from a mere imperial residence into the spiritual center of the Islamic world.
A Fierce but Cultured Ruler
Despite his grim reputation as a warrior, Sultan Selim was also a man of culture. He was an accomplished poet who wrote in both Turkish and Persian, and he was a great patron of theology and history. He filled the imperial treasury to the brim, leaving a famous testament that his successors should not spend more than he had earned. His short but explosive reign laid the military, economic, and spiritual foundations upon which his son, Suleiman the Magnificent, would build the empire’s Golden Age.
The Full Treasury and a Sultan’s Vow
Sultan Selim’s economic achievement was so immense that he sealed the Imperial Treasury with his own imperial seal and left a famous testament. He decreed that the treasury should remain sealed with his seal until a successor managed to fill it even more. The legend holds that the treasury remained sealed with Sultan Selim’s seal until the end of the empire, as no other sultan could surpass his fiscal success. This act was more than a boast; it was a powerful symbol of his belief that an empire’s strength was built not just on conquest, but on a full treasury that could fund its ambitions and ensure its stability.
