The Conflict of the Orders, sometimes referred to as the Struggle of the Orders, was a political struggle between the plebeians (commoners) and patricians (aristocrats) of the ancient Roman Republic lasting from 500 BC to 287 BC in which the plebeians sought political equality with the patricians. It played a major role in the development of the Constitution of the Roman Republic. Shortly after the founding of the Republic, this conflict led to a secession from Rome by Plebeians to the Sacred Mount at a time of war. The result of this first secession was the creation of the office of plebeian tribune, and with it the first acquisition of real power by the plebeians.
