Provinces of Nigeria
The Provinces of Nigeria are a former administrative division in Nigeria, which were in use in Colonial Nigeria and shortly after independence; from 1900 to 1967.

Northern Nigeria and Southern Nigeria were also sometimes known as the Northern Provinces or Southern Provinces respectively. Currently, Nigeria is a federation of 36 states.
