Final answer:
The Arab invasion, Bantu migration, and trade were all ways to try to unite different cultural groups of the African Kingdom.
Step-by-step explanation:
The Arab invasion, Bantu migration, and trade were all ways to try to unite different cultural groups of the African Kingdom.
The Arab invasion connected North Africa to the Middle East and spread Islam, which united people behind one God and one set of religious practices.
The Bantu migration spread kindred languages, cultural practices, and technical know-how throughout the continent, leading to a common cultural framework. Trade in gold, salt, and slaves also brought different groups together and allowed them to escape their ecological niches.
