Republicanism is a political ideology centered on the belief that a government should be based on the consent of the governed and that power resides in the people rather than a monarch. This principle emphasizes civic virtue, the common good, and the importance of a representative government that safeguards individual rights while promoting the welfare of the community. The rise of republicanism in the context of early American politics significantly influenced the structure of government during the Federalist Era and played a key role in shaping political parties.
