During the period of the New Kingdom in Egypt, much of Nubia came under the direct rule of the Egyptian government. Egyptian colonies, trading posts and garrisons were established, from which the Egyptians exercised a tight control over the country. The chiefs of the pastoral tribes which roamed the grasslands away from the river were given Egyptian titles and became client princes in an Egyptian-controlled system of indirect rule. A major purpose of this system was to control the valuable mines and trade routes which ran through this region.
With the decline of Egyptian power in the past couple of centuries, the Egyptian ruling class has remained in place, and Nubia has become the seat of independent kings, with a court and culture very similar to that of their northern neighbours.
