Explanation

Pre-colonial Nigeria had extensive trade networks. North: trans-Saharan trade (gold, salt, slaves, leather, textiles). South: Atlantic trade (slaves, palm oil, ivory). Internal: exchange between forest and savanna zones.

Trade items: kola nuts (south to north), salt (desert to forest), cloth (Kano famous), iron goods, horses, leather. Cowrie shells served as currency. Markets were major social and economic centers.

Trade brought: wealth to kingdoms, cultural exchange, Islam (via trans-Saharan routes), and eventually European influence (via Atlantic coast). Trade networks predated and shaped colonial boundaries.
