Most Hausa grow crops, raise livestock, and engage in trade. For centuries they joined Sahelian caravans, which increased when European colonization brought economic stability.
The north of Nigeria is under Sharia law, where the military wages war on Boko Haram jihadists. Many in the northern region flee both war and persecution. The Islamic north is also a poorer culture strongly influenced by the wealthier, more productive, and more populated coastal south, as well as by the wealthy Islamic shadow of the Arab Middle East. The Hausa gravitate both ways.
Nigerians are keenly aware of their past tribal wars, of the role the Hausa played as Muslim aggressors throughout the centuries, and of their role in the violent decades following independence in 1960. The Hausa continue to play a dominant role in Nigeria’s politics and military.
Despite an aggressive coastal economy and strong population growth, both the north and south of Nigeria remain plagued with corruption, ranked in 2018 as the 31st most corrupt of 175 nations.
