Egypt, one of the first empires, was organized and unified around 3100 and 2900BC. It was a semi-independent state until the Roman conquest in 30BC. Egypt's long existence could have been because of their isolation from the rest of the world. The unending desert surrounded it on three sides and the Isthmus Suez, the only entrance into Egypt, surrounded it on the other. This was good for the Egyptians, since they didn't like change. A possible reason for their dislike could have been for their hierarchy system. The Gods were at the top, the dead under the Gods, the pharaoh was under the dead, and the citizens were at the bottom. This is where the saying "If it works, do not try to fix it" comes from. If life is acceptable as it stands, why change it?
Egypt was fine as it was.…
