The answer is the Shays' Rebellion. This was
an equipped rebellion throughout 1786 and 1787. Revolutionary War
veteran Daniel Shays commanded four thousand rebels (named
Shaysites) in a rebellion alongside apparent fiscal and civil privileges prejudices.
The rebellion happened in a political atmosphere where improvement of the
country's governing document, the Articles of Confederation, was extensively
seen as compulsory. The shock of Shays' Rebellion pull back retired
General George Washington to go back into the public
life, heading to his two periods as the US' first President.
