The dawn of the civilisation 
        
               At the end of the 4 th millennium in the vicinity of the First and
          Second Cataracts a new culture, today called A-Group (or A-Horizon),
          appeared. A major role in its development must have been played by
          significant cultural influences from Upper Egypt, where the beginnings
          of the ancient civilization of the pharaohs were being established
          at the same time. Apart from animal husbandry, trade became the source
          of the group's wealth: in exchange for skins of wild animals, gold,
          ivory, ostrich eggs and feathers as well as precious ebony wood, the
          inhabitants of what was to become Egypt offered copper tools, foodstuffs
          (oil, honey and beer) and above all pottery of highest quality. 
          
        
        
Elephantine - "Elephant Town" 
        
               The development of trade enriched the local tribal chieftains
        and helped the penetration of Egyptian culture and religion into Nubia.
        To carry out trade with the south, an Egyptian factory was established
        on the island of Elephantine (ancient 
Abu , "Elephant Town",
        modern Aswan). Soon however, Egyptians started to wage war against the
        inhabitants of Lower Nubia - one of such conflicts seems to be memorialized
        in a graffito at Jebel Sheikh Suliman near Wadi Halfa, where the name
        of pharaoh Djer is accompanied by an image of a bound Nubian chieftain.
        Possibly, due to the changes in the Egyptian policy towards the south
        during the 1 st Dynasty (ca 3000 - 2890) most A-Group settlements were
        abandoned.
