Treaty of Constantinople (1454)
Treaty of Constantinople (1454)
Signed on April 18, 1454, between the Ottoman Empire and the Republic of Venice, shortly after Mehmed II captured Constantinople in 1453. The treaty ended Venice’s hopes of destroying the Ottoman state or retaking Constantinople for Christendom. Venice gained freedom to trade in the eastern Mediterranean. The agreement weakened the idea of an alliance of Italian rulers against the Ottomans, a plan supported by Pope Nicholas V, and it strained Venice’s relationship with the papacy.
