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.
William Mc Coskry, the Acting Consul in Lagos with Commander Bedingfield convened a meeting with Oba Dosunmu on 30 July 1861 aboard HMS Prometheus where Britain's intent was explained and a response to the terms were required by August 1861.
Dosunmu resisted the terms of the treaty but under the threat to unleash violence on Lagos by Commander Bedingfield, Dosunmu relented and signed the Lagos Treaty of Cession on 6 August 1861.
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.resulting in the installation of Oba Akitoye and the ouster of Oba Kosoko.Oba Akitoye then signed the Treaty between Great Britain and Lagos abolishing slavery.The remainder of modern-day Nigeria was seized in 1887, and when the Colony and Protectorate of Nigeria was established in 1914, Lagos was declared its capital, continuing as such after the country's independence from Britain in 1960.Along with migrants from all over Nigeria and other West African nations were the returnee ex-slaves known as Creoles, who came from Freetown, Sierra Leone, Brazil and the West Indies to Lagos.
