Answer(s):
1st: Clerics and Kings on the top of the hierarchy, Farmers and Warriors beneath them, Fishermen on the third layer, Weavers and Leatherworkers on the fourth layer and Smiths and Griots at the bottom layer.
2nd: The political systems of African kingdoms shared similarities with European kingdoms. The king, such as Mansa Musa of Mali and Sonni Ali of Songhay, had near absolute power and there was no separation of power. The king and his councilors and advisors carried out executive, legislative, and judicial functions.
3rd: First, the early African kingdoms and empires relied heavily on trade with other people. Besides the trade in ivory, gold, and other commodities identified earlier, produce from agriculture was also exchanged in the form of cash crops. These trade relations put them at the center of the economy of the east and west.
Hope this helped ;)
