The Persians did not come from Mesopotamia - they were a vassal of Media, which they took over and then with their help, conquered the Babylonian Empire in Mesopotamia. They then expanded this empire to include all the Middle East, Egypt and east as far as today's Pakistan. This empire lasted for two hundred years until taken over by Alexander the Great.
