What is a republic?

A republic is a form of government in which the head of state is not a hereditary monarch, supreme power resides with the people, and that power is exercised through elected representatives chosen for limited terms. The word comes from the Latin res publica, meaning the public thing or the public matter.

The American Founders used the term carefully. James Madison, writing in Federalist No. 10 in 1787, contrasted a republic with a pure democracy. A pure democracy, he wrote, was a society where the people gather and vote directly on every public question, which could only work in small communities and tended to be unstable, prone to faction, and threatening to minority rights. A republic, in his terms, refined and enlarged public views by passing them through the medium of a chosen body of citizens, and could extend over a much larger territory and population.

Article IV, Section 4 of the Constitution requires that the United States guarantee to every state a republican form of government, although the Supreme Court has generally treated the meaning of that clause as a political question for Congress and the president to resolve rather than for courts. The Pledge of Allegiance, written in 1892 and amended several times since, refers to the United States as a republic, for which it stands.

American republicanism rejected European monarchies and the inherited privileges that went with them. Article I, Section 9 bars the federal government and Article I, Section 10 bars the states from granting titles of nobility. Officials hold office for fixed terms and must stand for election or reappointment. Even the president, the most powerful single official, cannot inherit office and is limited to two terms by the Twenty-Second Amendment.

Republics have taken many forms in history, including the Roman Republic from 509 to 27 BC, the Italian city-states of the Renaissance, the Dutch Republic of the seventeenth century, and modern republics in France, Germany, Brazil, and India. The American republic combined classical republicanism with separation of powers, federalism, judicial review, and a written constitution that protects individual rights against majorities, producing a model that has shaped democratic constitutional design around the world for more than two centuries.
