Mehmet; also known as el-Fātiḥ, الفاتح, "the Conqueror" in Ottoman Turkish; in modern Turkish, Fatih Sultan Mehmet; also called Mahomet II in early modern Europe) was Sultan of the Ottoman Empire twice, first for a short time from 1444 to September 1446, and later from February 1451 to 1481. At the age of 21, he conquered Constantinople and brought an end to the Byzantine Empire, transforming the Ottoman state into an empire. Mehmed continued his conquests in Asia, with the Anatolian reunification, and in Europe, as far as Bosnia and Croatia. Mehmed II is regarded as a national hero in Turkey, and Istanbul's Fatih Sultan Mehmet Bridge is named after him.
