Lagos is a port city and the most populous city in Nigeria. Officially, the population of Lagos was last recorded at 7,937,932. Lagos is the second fastest growing city in Africa and the seventh fastest in the world. Lagos was originally inhabited by the Awori subgroup of the Yoruba people. Under the leadership of their Olofin, the Awori moved to an island now called Iddo and then to the larger Lagos Island. In the 15th century, the Awori settlement was attacked by the Benin Empire following a quarrel, and the island became a Benin war-camp called 'Eko' under Oba Orhogba, the Oba of Benin at the time. Lagos is a metropolitan area which originated on islands separated by creeks, such as Lagos Island, fringing the southwest mouth of Lagos Lagoon whilst protected from the Atlantic Ocean by long sand spits such as Bar Beach, which stretch up to 100 km east and west of the mouth.
