Worked great for imperial Rome for a while - they let the the CEOs of the day (military generals) fight amongst each other and fight/conquer the Gauls, Franks, Teutons, etc. The generals and armies got to keep status and power if they brought the spoils back to Rome. Once in a while, one of the generals crossed the rubicon and the Senate called on the other generals to suppress that one.
