Lagos began as a small Yoruba kingdom known as «Eko» before Portuguese sailors and traders named it «Lagos» — Portuguese for «lakes» — in the 15th century, after the network of lagoons surrounding the settlement.
Lagos served as Nigeria's capital until 1991, when the seat of government formally moved to Abuja, but it has remained the country's economic and cultural powerhouse and by far its largest city, as well as a major centre of Nigeria's film industry, known as «Nollywood».
