How the Ottoman dynasty evolved from brutal fratricide to a stable, seniority-based succession

In short: For centuries, Ottoman succession was a lethal game of survival where princes fought to the death for the throne. Yet, this violent tradition eventually gave way to a rigid, bloodless system of seniority. Discover how the House of Osman transformed its internal power struggles into a uniquely regulated imperial order.

The Ottoman dynasty, founded by Osman I around 1299 in northwestern Anatolia, governed for over six centuries. In its early era, succession was defined by open competition. Princes were sent to govern provinces, gaining administrative experience while preparing to seize the capital upon their father's death. This often resulted in violent conflict, as the first son to reach the court and secure control typically claimed the throne. By the reign of Mehmed II, this practice of fratricide was legalized, and later sultans routinely executed their brothers to eliminate potential rivals.

A major shift occurred in the 17th century, moving away from this brutal competition toward a system of agnatic seniority. This transition began in 1617 when Ahmed I’s successor, Mustafa I, inherited the throne without being killed. This precedent established that the eldest living male relative—rather than the reigning sultan's son—would inherit the crown. This change was partly driven by the decline of fratricide's popularity and the emergence of the 'Golden Cage' or kafes, where princes were confined within the harem to prevent them from forming political factions or usurping power.

This new system of seniority aimed to ensure adult rulers and curb the influence of rival factions, though it often meant that sultans ascended the throne at an advanced age after decades of isolation. Despite attempts to introduce primogeniture in the 19th century, agnatic seniority remained the standard until the sultanate was abolished in 1922. Following the Turkish War of Independence, the dynasty was deposed, and its members were exiled, eventually adopting the surname Osmanoğlu as they transitioned into private life within the newly declared Republic of Turkey.
