Istanbul is the only city in the world that is situated over two continents; Asia and Europe. And the city is so important that despite being a Muslim country and only %3 of the Turkish territories is situated on Europe, Turkey is soon to be a part of European Union because this %3 belongs to Istanbul.
Ottoman Rule in Egypt (1517-1798)
The Ottoman Empire, founded in the late 13th century, had been steadily expanding. From its source in northwestern Anatolia the empire extended across the Dardanelles into southeastern Europe. In the 15th century, after it had conquered most of the Balkan region, the empire turned south and east, absorbing most of the petty states of Muslim Anatolia.
