Arewa or Arewaland is a Hausa word which means "The North". The term is used to refer to Northern Nigeria general. The terms Arewa (literally "north") and Arewacin Nijeriya (literally "Northern Nigeria") are used in Hausa to refer to the historic region geopolitically located north of the River Niger.
In the history of Nigeria specifically, it is used to refer to the pre-1967 Northern Region, Nigeria. In Niger, it has a very specific meaning: a small pre-colonial animist dominated state of the Dallol Maouri valley, known for the indigenous "Maouri"/"Mawri" Hausa culture. In Nigeria, some towns have been called simply "Arewa" in the past, before British colonisation.
