The values, ideals and concept of republicanism have been discussed and celebrated throughout the history of the United States. As the United States has no formal hereditary ruling class, republicanism in this context does not refer to a political movement to abolish such a class, as it does in countries such as the UK, Australia, and Netherlands. Instead, it refers to the core values that citizenry in a republic have, or ought to have. Political scientists and historians have described these central values as liberty and inalienable individual rights; recognizing the sovereignty of the people as the source of all authority in law; rejecting monarchy, aristocracy, and hereditary political power; virtue and faithfulness in the performance of civic duties; and vilification of corruption. These values are based on those of Ancient Greco-Roman, Renaissance, and English models and ideas. Articulated in the writings of the Founding Fathers (particularly Thomas Jefferson, James Madison, and John Adams), they formed the intellectual basis for the American Revolution — the Declaration of Independence (1776), the Constitution (1787), and the Bill of Rights (1791), as well as the Gettysburg Address (1863). Politicians and scholars have debated the connection of these values with issues like honest government, democracy, individualism, property rights, military service; or their compatibility with slavery, inequitable distribution of wealth, economic self-interest, limits on the rights of minorities, and national debt. In the United States Constitution, republic is mentioned once, in section four of Article Four, where it is stated: "The United States shall guarantee to every State in this Union a Republican Form of Government ...". Two major political parties in American history have used the term in their name — the Democratic-Republican Party of Thomas Jefferson (1793–1824; also known as the Jeffersonian Republican Party) and the Republican Party, (founded in 1854 and named after the Jeffersonian party). American Revolution and republican virtue Virtue and patriotism The colonial intellectual and political leaders in the 1760s and 1770s closely read history to compare governments and their effectiveness of rule. The Revolutionists were especially concerned with the history of liberty in England and were primarily influenced by the "country party" (which opposed the "court party" that held power). Country party philosophy relied heavily on the classical republicanism of Roman heritage; it celebrated the ideals of duty and virtuous citizenship in a republic. It drew heavily on ancient Greek city-state and Roman republican examples. The country party
