The Tiv live in Nigeria on both sides of the Benue River, 220 kilometers from its confluence with the Niger. The Tiv language is a subgroup of the Niger-Congo language family. The Tiv are subsistence farmers growing yams, cassava, and sweet potatoes. All Tiv reckon patrilineal descent from their earliest ancestor and see themselves as a single patrilineage. Their large-scale patrilineal genealogy is also the basis of their land-tenure system in which every Tiv male has a right to a farm. Tiv maintain a calendar built on five-day market cycles in which goods move from smaller markets to large central markets, and then for export.
