What event demonstrated the government's ability to suppress rebellion against federal tax policy?

The Whiskey Rebellion is the event that clearly demonstrated the federal government's ability to suppress rebellion against its taxation policies. Occurring in the early 1790s, this rebellion arose when farmers in western Pennsylvania protested against a federal excise tax on whiskey, which they found burdensome. The federal government, led by President George Washington, responded decisively by sending a militia of about 13,000 troops to quell the uprising.

This display of military force marked a significant moment in establishing the authority of the federal government to enforce its laws and collect taxes. It set a precedent for how the federal government would deal with domestic dissent and ensured that the young nation could assert its legislative power without yielding to violent protests. The suppression of the Whiskey Rebellion affirmed the government's commitment to maintaining order and compliance with federal statutes, contrasting earlier instances of resistance, such as Shays' Rebellion, which highlighted the weaknesses of the Articles of Confederation and the inability of the government to effectively respond to such challenges.
