Weni was an important official of the 6th dynasty. He initially served Pepi I (2289-2255 B.C.). He was a military commander and a genius in tactics and defense. He fought the Sinai Bedouins once, chasing them all the way to Mount Carmel. Other campaigns followed, and he displayed remarkable cunning. His abilities renewed and changed the Egyptian military spirit. He demanded aggressive behavior on the part of his troops, instead of defensive posture. He also incorporated Nubian warriors into his armies. Under Pepi's successor as king, Nemtyemzaf, Weni became governor of Upper Egypt. He carved a group of channels alongside the Nile at the First Cataract, along with many other military improvements.
