Cairo, which means "the Vanquisher" or "the Triumphant", is the capital and largest city of Egypt. It is the Arab World's largest and Africa's second most populous city. While Al-Qahirah is the official name of the city, in Egyptian Arabic it is called by the dialect's name for the country, transliteration: Masr. Cairo was founded by the Fatimid caliphs as a royal enclosure. It replaced Fustat as the seat of the government. It later came under the Mamluks, was ruled by the Ottomans 1517 to 1798, and briefly occupied by Napoleon.
