On September 25, 1789, the First Federal Congress of the United States proposed to the state legislatures twelve amendments to the U.S. Constitution. The first two, concerning the number of constituents for each Representative and the compensation of Congressmen, were not ratified.* Articles three through twelve—known as the Bill of Rights—were ratified by the states on December 15, 1791, and became the first ten amendments to the U.S. Constitution. The Bill of Rights contains guarantees of essential rights and liberties omitted in the crafting of the original Constitution.
