An amendment is a formal revision or addition to the U.S. Constitution. There have been 27 amendments to the Constitution; the first 10 of these amendments are known as the Bill of Rights.
In theory, there are two different ways that an amendment can be added to the Constitution:
So far, as of 2024, new amendments have been ratified only by the first method. A Constitutional Convention has never been called. More than 11,000 amendments have been proposed, but only 27 have been ratified.
The Supremacy Clause says that the U.S. Constitution is the “supreme law of the land,” or that federal law overrides state laws.
The Constitution would become the “law of the land” when 9 of the 13 original states ratified it. The process of ratifying the Constitution became a fierce public debate, with two factions emerging: the Federalists and the Anti-Federalists. The Federalists advocated for the ratification of the Constitution, while the Anti-Federalists vehemently opposed it. James Madison, Alexander Hamilton, and John Jay wrote a defense of the Constitution in the Federalist Papers, which explained the intentions behind the new structure of government and how it protects the rights of the people.
