The Lagos Colony and Protectorate was amalgamated with The Protectorate of Southern Nigeria in 1906. This was done as part of the British colonial administration's efforts to consolidate and streamline its control over Nigeria. Before this amalgamation, Lagos Colony and Protectorate and the Protectorate of Southern Nigeria were administered separately, with different laws and systems of government. The amalgamation brought them together under a single administration, with a unified legal and administrative system, and marked a significant step towards the eventual creation of a single, unified Nigeria.
