Mustafa I (1617–1618, 1622–1623) was the 15th and 17th Sultan of the Ottoman Empire, unique for having ruled twice, both times under unusual and troubled circumstances. Often referred to as “Mustafa the Mad”, his reigns were short, unstable, and dominated by court factions. His mental condition and the political manipulations of the palace elite made him a puppet ruler, and his time on the throne symbolized the deepening instability of the Ottoman succession system during the 17th century.

🧠 Mental Health and Background
- Mustafa I was the younger brother of Sultan Ahmet I.
- Unlike previous Ottoman practices, Ahmet I had spared Mustafa’s life, likely due to a desire to end the fratricidal tradition and allow for more flexible succession.
- Mustafa had spent much of his early life in isolation in the Kafes (the Cage) — a form of confinement used for potential heirs to prevent rebellion.
- This long period of isolation is believed to have seriously affected his mental health, leading to erratic behavior later in life.
- Contemporary accounts and later historians often describe Mustafa as mentally unwell, prone to delusions, hallucinations, and unpredictable behavior. However, some scholars argue that these claims may have been exaggerated by his political enemies.
🏰 First Reign (1617–1618)
- After the death of Ahmet I in 1617, Mustafa I was brought to the throne instead of Ahmet’s son Osman, even though Osman was alive and capable.
- The imperial court and viziers chose Mustafa due to the uncertainty of succession law, as the empire was transitioning from fratricide to seniority-based succession.
- Mustafa’s reign quickly descended into chaos due to his erratic behavior and inability to govern. He was seen playing with coins, talking to himself, or pulling off turbans from courtiers’ heads.
- After just over a year, he was deposed in 1618 and replaced by Osman II, who was more capable and mature.
⚔️ Interlude and Return
1. Osman II’s Reign and Assassination
- Osman II, though energetic and reform-minded, alienated the Janissaries (elite military corps) by trying to curb their power.
- In 1622, the Janissaries revolted, captured, and murdered Osman II, shocking the empire and marking one of the first regicides in Ottoman history.
2. Second Reign (1622–1623)
- In the aftermath of Osman’s murder, Mustafa I was restored to the throne by the faction that orchestrated Osman’s downfall.
- However, the situation quickly fell apart. Mustafa remained mentally unfit and again acted in a disturbed manner.
- His mother, Halime Sultan, effectively ruled in his name, but the empire plunged deeper into unrest, with rebellions and military mutinies erupting.
⚠️ Downfall and Deposition
- The chaos and factional strife following his second reign made it clear that Mustafa could not remain on the throne.
- In 1623, the ulema (religious scholars), Janissaries, and imperial statesmen agreed to depose Mustafa I permanently.
- He was replaced by Murad IV, the young son of Ahmed I, with a regency governed by his mother Kösem Sultan.
- Mustafa I was returned to confinement in the palace, where he lived out the rest of his life in seclusion.
⚰️ Death and Legacy
- Mustafa I died in 1639, having spent the final 16 years of his life in confinement.
- His legacy is largely remembered for the instability of his reigns, the dangers of unclear succession, and the manipulative role of court factions, particularly the Janissaries and queen mothers.
- He is one of the most tragic figures in Ottoman history—likely a victim of palace politics, mental illness, and systemic breakdown.
📜 Summary
Mustafa I (1617–1618, 1622–1623) ruled the Ottoman Empire during two short and tumultuous periods. His mental health issues, exacerbated by years in isolation, and the manipulative actions of palace factions, made him an ineffective and largely symbolic ruler. His reigns highlight the fragility of the Ottoman succession system, especially during a time when the empire was transitioning from fratricide to seniority. Though he had no notable achievements, his time on the throne played a key role in shaping the political reform and centralization efforts that would follow under Murad IV.
