What is a change made to the Comstitution?

A change made to the Constitution is known as an amendment. Amendments can be proposed by a two-thirds majority in both houses of Congress or by a constitutional convention called by two-thirds of state legislatures. Once proposed, an amendment must be ratified by three-fourths of the state legislatures or by conventions in three-fourths of the states to become part of the Constitution. An example is the First Amendment, which guarantees freedoms concerning religion, expression, assembly, and the right to petition the government.
