Ivoirité: citizenship converted into ancestry test
Ivoirité was a 1990s political doctrine of 'authentic' Ivorian identity that redefined belonging by ancestral origin rather than birth, residence or legal nationality. Northern Ivorians share names, languages and Islam with Sahelian migrants, so the doctrine made them presumptive foreigners. A category built to exclude outsiders therefore expanded to disenfranchise a large share of the country's own citizens and supplied a grievance for rebellion.
