What conflict in Massachusetts demonstrated the need to change the Articles of Confederation?

Shays' Rebellion, which occurred in 1786-1787, demonstrated the need to change the Articles of Confederation. This armed uprising, led by farmer Daniel Shays, protested against economic injustices and the lack of governmental support for struggling farmers facing debt and tax burdens. The inability of the federal government to respond effectively to the rebellion highlighted the weaknesses of the Articles, particularly in maintaining order and ensuring stability, ultimately leading to calls for a stronger central government and the drafting of the U.S. Constitution.
