When was British colonization in Nigeria?

The process of colonizing what is modern-day Nigeria by the British started in approximately 1850 and was completed by 1905. Nigeria remained a colony of Great Britain until 1960 when the country gained its independence.

Until 1914, the northern and southern portions of Nigeria were separate British colonies.

Nigeria is one of 17 African nations that gained independence in 1960. The process towards an independent Nigeria began in about 1945, with the colony being extended greater independence over time. About 7 years after independence, a civil war erupted in the country, resulting in the deaths of over 1 million people during the course of the conflict.
