Answer: The Ottoman conquest of Constantinople marked the end of the thousand-year Byzantine Empire.
Explanation:
The fall of Byzantium or its capital, Constantinople, in 1453 marked the end of the Byzantine Empire. The conquest of Constantinople was one of the priorities of the Ottomans, as it was an important strategic location that would allow for easier maneuvering by the Ottomans in every respect, between east and west. The conquest of Constantinople was followed by the octopus of Sultan Mehmed II, who was nicknamed "El Fatih" (Conqueror) after this endeavor. The fall of Constantinople will continue the Ottoman domination and territorial integration of the Ottomans into the interior of Europe.
