Hyksos-the hyksos invaded the eastern nile delta (c 1720 bc) and controlled most of egypt for 150 years. they had horses and chariots, but the egyptians fought on foot. eventually the egyptians learned to fight with chariots and horses and drove them away (c 1570 bc). ahmose i was the egyptian pharaoh who finally expelled the hyksos from egypt, after the death of his father and of his brother kamose, who fought them. he first drove them back to their capital avaris and laid siege to the city. he left the siege of avaris in the control of his military commanders so that he was free to placate a rebellion in the theban region. when ahmose returned to avaris he found that negotiations had been taking place between the hyksos and his military commanders who allowed them to leave egypt in return for surrendering the city.
