However, Lagos still remains the financial centre of the country, and also grew to become the most populous conurbation in the country.
Due to rapid urbanization, the city expanded to the west of the lagoon to include areas in the present day Lagos Mainland, Ajeromi-Ifelodun and Surulere.
This led to the classification of Lagos into two main areas - the Island, which was the initial city of Lagos, before it expanded into the area known as the Mainland.
Before the creation of Lagos State on , Lagos, which was the country's capital had been administered directly by the Federal Government as a Federal Territory through the Federal Ministry of Lagos Affairs, while the Lagos City Council (LCC) governed the city.
Lagos city was split into the present day seven Local Government Areas (LGAs), while the other towns now make up 13 LGAs in the state.
The city, with its adjoining conurbation, is the largest in Nigeria, as well as on the African continent.
Note that this definition is rarely used in present day; the expanded metropolitan area is now a more accepted definition of Lagos.The present-day Lagos state has a high percentage of Awori, who migrated to the area from Isheri along the Ogun river.Throughout history, it was home to a number of warring ethnic groups who had settled in the area.The Creoles contributed to Lagos' modernisation and their knowledge of Portuguese architecture can still be seen from the architecture on Lagos Island.Since the 19th century, Lagos gradually transformed to a melting pot of Africans and Europeans.
