Indian Ocean trade was more diverse in participants (African, Arab, Persian, Indian, Chinese vs primarily North African-West African)
4
Both created wealthy cosmopolitan cities that became centers of learning
5
Trans-Saharan trade focused heavily on gold-salt exchange; Indian Ocean trade had more diverse goods
