Mehmed II (Ottoman Turkish: محمد ثانى, Meḥmed-i s̠ānī; Turkish: II. Mehmet; also known as el-Fātiḥ, الفاتح, "the Conqueror" in Ottoman Turkish; in modern Turkish, Fatih Sultan Mehmet Han; also called Mahomet II in early modern Europe), also known as Muhammed bin Murad, Mehmed the Conqueror, Grand Turk, Kayser-i Rûm (Caesar of Rome) and Turcarum Imperator, and Fatih Sultan Mehmed (30 March 1432 – 3 May 1481), was an Ottoman sultan who ruled first for a short time from August 1444 to September 1446, and 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. Mehmed continued his conquests in Anatolia with its reunification, and in Southeast Europe as far west as Bosnia. Being a highly regarded conqueror, Mehmed is considered a hero in modern-day Turkey and parts of the wider Muslim world. Among other things, Istanbul's Fatih district, Fatih Sultan Mehmet Bridge and Fatih Mosque are named after him.
