By the early 15th century, the Byzantine Empire was reduced to just Constantinople and its environs, along with Morea in Greece, making it an enclave inside the Ottoman Empire; after a 53-day siege the city eventually fell to the Ottomans, led by Sultan Mehmed II, on 29 May 1453,[11] whereafter it replaced Edirne (Adrianople) as the new capital of the Ottoman Empire.[12] ./cache/en-wikipedia-org-4407.html ./txt/en-wikipedia-org-4407.txt
