Kush was the first large African civilization in Nubia, the region in Northwest Sudan. Their agriculture was dependent on the Nile River and their first neighbors were Egyptians who conquered the kingdom of Kush and ruled over them for almost five hundred years. Over time, the Egypt grew weaker and the Kush grew stronger until they finally defeated Egypt. During that time Kush wore Egyptian clothes, had Egyptian names and adopted their religious practices. They were defeated by the Assyrians in the end and lost a lot of their trade power.
