Answer:
Sahel, dry and hot climate
Step-by-step explanation:
The earliest kingdoms in Africa appeared in the region known as the Sahel, which is a transitional zone between the Sahara Desert to the north and the savannas and forests to the south. This region spans across several countries in West Africa, including Mali, Burkina Faso, Niger, and Nigeria.
The climate in the Sahel is semi-arid, with long, hot, and dry periods, followed by short, intense rainy seasons. This climate supported the growth of vegetation, which provided a source of food for both humans and animals, and allowed for the development of agriculture. The region's location also made it a hub for trade and commerce, with various caravan routes connecting it to other regions of Africa and the Mediterranean world.
The earliest kingdoms in the Sahel region included the Ghana Empire, which emerged around the 6th century AD, and the Kingdom of Mali, which rose to power in the 13th century AD. These kingdoms were built on the wealth generated by the gold and salt trade, and they developed complex political and economic systems that allowed them to thrive for centuries.
