kush civilization had its center in the region of nubia. this was in northern sudan of today. we know about it through the egyptians who moved south around 2500 bc. when the middle kingdom of egypt ended an independent kingdom of kush developed. about 1500 bc egyptians moved southwards again, but this time met organized resistance. historians are not sure whether this resistance came from many city states or a single unified empire. the egyptians won, and the region became a colony of egypt under the control of thutmose i. the region supplied egypt with resources.
