Introduction: A Bloodline Secured by Bloodshed
The Ottoman Empire, one of the most powerful dynasties in history, spanned over six centuries. But behind the grandeur of its palaces and military conquests lay a brutal political reality: the systematic elimination of male relatives to secure the throne. Known as **fratricide**, this practice was not only accepted but legalized, institutionalized, and, at times, even romanticized. Fratricide in Ottomans was seen as a necessary evil to preserve the empire’s unity and prevent civil war. Its roots trace back to the early formative centuries of Ottoman statecraft, long before Netflix was flooded with “Suleiman the Magnificent” reenactments and melodramatic slow-motion poisonings.

Fratricide in Ottomans Becomes Law: Mehmed II and the Legalization of Royal Bloodshed
The pivotal moment came with Sultan Mehmed II, known as “the Conqueror” for his 1453 capture of Constantinople. In his law code, he explicitly authorized the new sultan to kill his brothers: “Whichever of my sons inherits the sultanate, it is acceptable for him to kill his brothers for the sake of order (nizam-ı âlem).” This codification marked the official recognition of fratricide as a political tool. It wasn’t mere cruelty; it was, paradoxically, seen as a mercy to the empire. Ottoman rulers feared the kind of fraternal civil war that had ravaged other empires, including the Seljuks and Mongols.

Indeed, fratricide was seen on other dynasties as well.
Palace Protocol: The Kafes and the Dance of Delay
By the 17th century, the Ottomans developed more subtle ways to curb dynastic chaos. The infamous “Kafes” (or “Cage”) system emerged, wherein princes were confined in luxurious but restrictive palace quarters, often for decades, to prevent rebellion. Though it spared their lives, the system produced sultans with limited education, socialization, or real-world experience. If you think Halit Ergenç’s portrayal of Suleiman seemed moody, imagine living your whole life behind a latticed window, waiting for your brother to die or kill you. Here is a modern reflection of Kafes system in Turkish rock music by Pentagram:
Notable Examples of Ottoman Fratricide
- Bayezid II vs. Cem Sultan: After Mehmed II’s death, Bayezid’s rival brother Cem fled the empire and became a pawn in European politics. Though not a case of outright execution, it set the stage for future interventions by foreign powers.
- Selim I: Upon ascending the throne in 1512, Selim had his brothers executed swiftly to prevent rebellion. He even had their young sons killed—just in case.
- Murad IV: Known for his personal involvement in purging opponents, Murad IV executed his own brother Bayezid in 1635.
- Mehmed III: Upon taking the throne, he had 19 brothers and half-brothers strangled with silk cords in one night—possibly the most extreme single act of fratricide in Ottoman history.
A Practice in Decline
Fratricide declined in the 17th century as public sentiment shifted and as palace politics offered alternative methods of control. The rise of powerful valide sultans (queen mothers) and eunuchs, as well as institutionalized bureaucracy, gave rise to more layered succession politics. The Cage system, combined with political marriages and strategic appointments, gradually replaced outright murder as the norm.
Between Barbarism and Statecraft
To the modern eye, Ottoman fratricide seems shockingly cruel. Yet in the logic of dynastic survival, it was a calculated and codified solution. It prevented long and bloody succession wars, allowing the empire to project stability even as its foundations were soaked in the blood of princes.
And while the “Suleiman the Magnificent” TV series might skim over these darker realities, the real Ottoman court had more plot twists, assassinations, and moral ambiguity than a decade’s worth of soap operas. To borrow from modern media: if Game of Thrones had a copyright claim, the Ottomans would likely have a case.
