The rebellion led by Daniel Shays in 1786 against economic injustices in the U.S. is known as Shays' Rebellion. This armed uprising took place in Massachusetts and was primarily driven by discontent among farmers facing economic hardship due to heavy taxation and debt. Many were at risk of losing their farms and livelihoods. The rebellion highlighted the weaknesses of the Articles of Confederation, as the federal government struggled to respond effectively. It underscored the need for reform in governance and economic policies, ultimately contributing to the drafting of the U.S. Constitution in 1787.
