The rebellion led by Daniel Shays in 1786-1787 is known as Shays' Rebellion. It was an armed uprising in Massachusetts in response to economic hardships, high taxes, and aggressive debt collection that threatened farms and livelihoods, particularly among rural farmers. Participants, primarily veterans of the American Revolution, sought to protest against the state government's policies and demanded reforms, including the cessation of tax and debt collection. The rebellion highlighted the weaknesses of the Articles of Confederation and led to calls for a stronger federal government, ultimately contributing to the drafting of the U.S. Constitution.
