The C-Group culture developed within the territory controlled by the pharaohs of the Old and Middle Kingdoms, known to the Egyptians as Wawat or Irchet. Although the people of C-Group in many cases occupied the same settlements as the communities of A-Horizon, there is no direct evidence for ethnic relationship between the two cultures. Despite the military occupation the inhabitants of the frontier areas managed to gain some profits from the Egyptian civilization made it possible to spread the use of dried silt brick, and the settled way of life led to progress in the construction of human dwellings, fortified settlements included. The specific burial ritual included burials covered with earthen-stone barrows, animal sacrifice and providing the dead with small magic figurines and equipment proper to their social status and occupation (tools, weapons).
