The Ottoman Empire (1299 to 1902) was a multi-ethnic and multi-religious Turkish ruled state which, at the
height of
its power (16th – 17th centuries), spanned three continents, controlling much of Southeastern Europe, the Middle East and North Africa, stretching from the Strait of Gibraltar (and, in 1553, the Atlantic coast of Morocco beyond Gibraltar) in the west to the Caspian Sea and Persian Gulf in the east, from the edge of Austria, Slovakia and parts of Ukraine in the north to Sudan, Eritrea, Somalia and Yemen in the south.The
empire was at the centre of interactions between the Eastern and Western worlds for six centuries. At the
height of its power, the Ottoman Empire contained 29 provinces, in addition to the tributary principalities of Moldavia, Transylvania, and Wallachia. With Constantinople (today known as Istanbul) as its capital, the Ottoman Empire was in many respects an Islamic successor to earlier Mediterranean empires — namely the Roman and Byzantine empires. As such, the Ottomans regarded themselves as the heirs to both Roman and Islamic traditions.
