Trans-Saharan trade, dominated by Berber (Amazigh) merchants, transformed the Soninke-founded kingdom of Ghana (Wagadu) from a loose network of farming villages into West Africa's first great empire (c. 300–1100 CE).
Ghana lay at the southern terminus of the major trans-Saharan route, connecting the gold fields of the upper Senegal/Niger with North African salt, textiles, and Mediterranean goods.
Ghana taxed every load of salt, gold, ivory, and slaves passing through. Revenue funded:
Almoravid incursions from Morocco (1076) disrupted trade and weakened central authority, leading to fragmentation.
Legacy: The Berber-Ghana commercial axis pioneered the West African gold-salt trade that later enriched Mali and Songhai.
