The Articles of Confederation, which form the basis of the new government of the United States, are ratified by Virginia. Many people believe that the lack of a strong central government is a mistake but sign off on the Articles anyway because some type of government was needed.

The 18th Amendment becomes the first and only amendment to be repealed when the 21st Amendment ends Prohibition. The 18th Amendment was extremely difficult to enforce and led to the rise in organized crime, which made millions of dollars selling alcohol.
