Mehmed II, commonly known as Mehmed the Conqueror, was an Ottoman sultan who ruled from August 1444 to September 1446, and then later from February 1451 to May 1481. At the age of 21, he conquered Constantinople (modern-day Istanbul) and brought an end to the Byzantine Empire. After the conquest Mehmed claimed the title Caesar of the Roman Empire, based on the fact that Constantinople had been the seat and capital of the surviving Eastern Roman Empire since its consecration in 330 AD by Emperor Constantine I.
