Within Rome, class divisions between the patricians and plebeians led to social and political challenges. The patricians were the ruling class who held all political power. In contrast, plebeians were common people excluded from government. To gain more political influence, plebeians formed their own councils in 494 BC. This threatened the patrician monopoly on power. While initially resisting changes, the patricians eventually cooperated and reformed the government to avert revolution from dividing Rome.
