Ahmed I vs Mohammad Reza Pahlavi

Upon his accession, Ahmed I spared his brother Mustafa I from execution, breaking the tradition of fratricide established by Mehmed II. Instead, he placed Mustafa in confinement (kafes). This reform changed Ottoman succession practices, ending the killing of brothers.

Ahmed I's empire signed the Treaty of Zsitvatorok with the Habsburg monarchy, ending the Long Turkish War. The treaty recognized the Habsburg emperor as equal to the Ottoman sultan and established a peace that lasted for decades.

Ahmed I's grand vizier Kuyucu Murad Pasha brutally suppressed the Celali rebellions in Anatolia, killing tens of thousands. The rebellion was crushed by 1610, restoring order but at a high human cost, leaving the countryside devastated.

Ahmed I commissioned the construction of the Sultan Ahmed Mosque in Istanbul, known as the Blue Mosque for its blue tiles. Completed in 1616, it was the first imperial mosque built in over 40 years and became a symbol of Ottoman architecture.

Mohammad Reza Pahlavi was reinstated as Shah after a CIA- and MI6-backed coup overthrew Prime Minister Mohammad Mossadegh. The coup ended Iran's democratic experiment and established the Shah's authoritarian rule, fueling long-term resentment.

The Shah launched the White Revolution, a series of land reforms, modernization, and women's suffrage. While it aimed to modernize Iran, it disrupted traditional rural life, concentrated wealth, and alienated the clergy and landowners.

The Shah hosted an extravagant celebration at Persepolis to mark 2,500 years of the Persian monarchy. The event was criticized for its opulence and disregard for Iran's poverty, fueling opposition to his regime.

Mass protests led by Ayatollah Khomeini overthrew the Shah's regime. Mohammad Reza Pahlavi fled Iran in January 1979, eventually seeking medical treatment abroad. He died in exile in Egypt in 1980, never returning to Iran.
