During the colonial era, Lagos was a powerful kingdom in what is now Nigeria. The British colonial government wanted to expand their influence in the region and in 1851, they signed a treaty with Oba Kosoko, who was then the ruler of Lagos. However, the British were not happy with Kosoko's rule, and in 1851, they deposed him and installed his nephew, Akitoye, as the new Oba of Lagos. Later in 1853, Kosoko returned to Lagos and reclaimed the throne with the help of the Egbas. However, in 1854, the British intervened again and this time, they drove Kosoko out of Lagos and installed Oba Dosumu as the new ruler. Therefore, the ruler that was driven out of Lagos by the British was Oba Kosoko.
