Kush civilization centered in the confluence of the Blue Nile and the White Nile, and the confluence of the River Atbara and Nile in what is now the Republic of Sudan. One of the earliest civilizations to develop in the Nile River Valley, the Kushite state was formed before a period of Egyptian incursion into the area. The Kushite civilization has also been referred to as Nubia. It is also referred to as Ethiopia in ancient Greek and Roman records. According to Josephus and other classical writers, the Kushite Empire covered all of Africa, and some parts of Asia and Europe at one time or another. The Kushites are also famous for having buried their monarchs along with all their courtiers in mass graves. The Kushites also built burial mounds and pyramids, and shared some of the same gods worshipped in Egypt, especially Amon and Isis.
The first cultures arose in Sudan before the time of a unified Egypt, and the most widespread is known as the Kerma civilization. It is through Egyptian, Hebrew, Roman and Greek records that most of our knowledge of Kush (Cush) comes.
