The Whiskey Rebellion, also known as the Whiskey Insurrection, was a tax protest in the United States beginning in 1791, during the presidency of George Washington. The so-called "whiskey tax" was the first tax imposed on a domestic product by the newly formed federal government. It became law in 1791, and was intended to generate revenue to help reduce the national debt. Although the tax applied to all distilled spirits, whiskey was by far the most popular distilled beverage in the 18th-century U.S. Because of this, the excise became widely known as a "whiskey tax". The new excise was a part of U.S. treasury secretary Alexander Hamilton's program to pay war debt incurred during the American Revolutionary War.
