Ivan III the Great vs Ruhollah Khomeini

Ivan III married Sophia (Zoe) Palaiologina, niece of the last Byzantine emperor. This marriage allowed Ivan to claim succession to the Byzantine Empire, adopt the double-headed eagle as a symbol, and promote Moscow as the Third Rome.

Ivan III conquered the Novgorod Republic after a series of campaigns. He abolished the veche (assembly) and removed the veche bell, incorporating Novgorod's vast territories into the Grand Principality of Moscow.

Ivan III faced the Mongol army of Khan Akhmat across the Ugra River. After weeks of stalemate, the Mongols withdrew without battle. This event ended 240 years of Mongol suzerainty over Russia.

Ivan III promulgated a new legal code, the Sudebnik, which standardized laws across the Russian lands. It restricted peasant mobility by limiting the time for transfer between landowners, a step toward serfdom.

Ivan III launched a war against Lithuania, capturing the cities of Bryansk, Dorogobuzh, and Putivl. The war ended with the Truce of 1503, which ceded significant territories to Moscow.

Khomeini was exiled from Iran after criticizing the Shah's White Revolution and granting of diplomatic immunity to US personnel. He settled in Najaf, Iraq, and later in France, where he continued to organize opposition to the Shah.

Khomeini led a popular revolution that overthrew the Shah's regime. He returned to Iran in February 1979 and established an Islamic Republic based on his doctrine of Velayat-e Faqih (Guardianship of the Jurist), with himself as Supreme Leader.

Khomeini supported the seizure of the US Embassy in Tehran by student militants, who held 52 American diplomats hostage for 444 days. The crisis deepened the rift with the US, led to economic sanctions, and consolidated Khomeini's power.

Khomeini led Iran through an eight-year war with Iraq, which began with an Iraqi invasion. The war resulted in hundreds of thousands of casualties and massive economic destruction, ending in a stalemate. Khomeini accepted a UN ceasefire in 1988.

Khomeini issued a fatwa calling for the death of author Salman Rushdie for his novel 'The Satanic Verses', which he deemed blasphemous. The fatwa led to international controversy, diplomatic tensions, and attacks on Rushdie's translators.
