The Grand Duke of Muscovy, Ivan III, marries Zoe (later Sophia) Palaiologina, the niece of the last Byzantine Emperor on November 12, 1472.
Their marriage took place in the Dormition Cathedral in Moscow cementing the connection between the Muscovite state and the legacy of the Byzantine Empire, contributing to Moscow's adoption of the title of "Third Rome" and the use of the double-headed eagle emblem.
