December 15 - 1791 - The Bill of Rights is Ratified
The United States Constitution was put in place because the Articles of Confederation were clearly not working, and the individual states agreed to ratify it in 1789. Nonetheless, many people were still greatly concerned about the power now entrusted in the federal government and the fact that many of the rights fought for in the Revolution were not guaranteed. So one of the first bills introduced in the first congress was actually a series of amendments to the Constitution that did all of these things, drafted by one of the chief architects and promoters of the Constitution, James Madison. By guaranteeing rights and delineating what powers belonged to the states, the Bill of Rights essentially completed the Constitution, allowing it to have more support among the states.
