Title: Shays' Rebellion
Content:  Shays Rebellion was an armed uprising in Western Massachusetts and Worcester in response to a debt crisis among the citizenry and in opposition to the state government's increased efforts to collect taxes both on individuals and their trades. The fight took place mostly in and around Springfield during 1786 and 1787. American Revolutionary War veteran Daniel Shays led four thousand rebels (called Shaysites) in a protest against economic and civil rights injustices. Shays was a farmhand from Massachusetts at the beginning of the Revolutionary War; he joined the Continental Army, saw action at the Battles of Lexington and Concord, Battle of Bunker Hill, and Battles of Saratoga, and was eventually wounded

Content:  action. In 1787, Shays' rebels marched on the federal Springfield Armory in an unsuccessful attempt to seize its weaponry and overthrow the government. The confederal government found itself unable to finance troops to put down the rebellion, and it was consequently put down by the Massachusetts State militia and a privately funded local militia. The widely held view was that the Articles of Confederation needed to be reformed as the country's governing document, and the events of the rebellion served as a catalyst for the Constitutional Convention and the creation of the new government. There is still debate among scholars concerning the rebellion's influence on the Constitution and its ratification.

They raided the shops of merchants and the homes of merchants and local professionals. This came to the attention of Brigadier John Ashley, who mustered a force of some 80 men and caught up with the rebels in nearby Sheffield late in the day for the bloodiest encounter of the rebellion: 30 rebels were wounded (one mortally), at least one government soldier was killed, and many were wounded. Ashley was further reinforced after the encounter, and he reported taking 150 prisoners.
Title: Daniel Shays
Content:  Daniel Shays (1747 –  September 29, 1825) was an American soldier, revolutionary and farmer famous for being one of the leaders and namesake of Shays' Rebellion, a populist uprising against controversial debt collection and tax policies in Massachusetts in 1786-87.

Content:   One early protest against the government was led by Job Shattuck of Groton, Massachusetts in 1782, who organized residents to physically prevent tax collectors from doing their work. A second, larger-scale protest took place in Uxbridge, Massachusetts on the Rhode Island border on February 3, 1783, when a mob seized property that had been confiscated by a constable and returned it to its owners. Governor Hancock ordered the sheriff to suppress these actions. Most rural communities attempted to use the legislative process to gain relief. Petitions and proposals were repeatedly submitted to the state legislature to issue paper currency, which would depreciate the currency and make it possible to pay a high-value debt with

Content:  On November 28, a posse of some 300 men rode to Groton to arrest Job Shattuck and other protest leaders in the area. Shattuck was chased down and arrested on the 30th, and was wounded by a sword slash in the process. This action and the arrest of other protest leaders in the eastern parts of the state radicalized those in the west, and they began to organize an overthrow of the state government. "The seeds of war are now sown", wrote one correspondent in Shrewsbury, and by mid-January rebel leaders spoke of smashing the "tyrannical government of Massachusetts." While government forces organized in the east, Shays, Day, and other rebel leaders in the west organized their forces, establishing regional regimental organizations that were run by democratically elected committees. Their first major target was the federal armory in Springfield. General Shepard had, however, pursuant to orders from Governor Bowdoin, taken possession of the armory and used its arsenal to arm a force of some 1,200 militia.
Title: History of Springfield, Massachusetts
Content:  Shays's Rebellion – the most crucial battle of which was fought at the Springfield Armory in 1787 – was the United States' first populist revolt. It prompted George Washington to come out of retirement, and catalyzed the U.S. Founding Fathers to craft the U.S. Constitution. On May 25, 1787, General Henry Knox, the Secretary of War, addressed the Constitutional Convention in Philadelphia: “The commotion of Massachusetts have wrought prodigious changes in the minds of men in the State respecting the Powers of Government... They must be strengthened, there is no security of liberty or property.” Shay's Rebellion was led, in part, by American Revolutionary War soldier Daniel Shays. In January 1787, Shays and the "Regulators" as they were then called, tried to seize the Arsenal at Springfield. The Arsenal at Springfield was not yet an Armory; however, it contained brass ordnance, howitzers, traveling carriages, muskets, swords, various military stores and implements, and many kinds of ammunition. If the Regulators had captured the Arsenal at Springfield, they would have had far more firepower than their adversaries, the Commonwealth of Massachusetts, led by former U.S. General Benjamin Lincoln.

Veterans had received little pay during the war and faced added difficulty collecting payments owed to them from the State or the Congress of the Confederation. Some soldiers began to organize protests against these oppressive economic conditions. In 1780, Daniel Shays resigned from the army unpaid and went home to find himself in court for non-payment of debts. He soon realized that he was not alone in his inability to pay his debts and began organizing for debt relief.

Daniel Shays had participated in the Northampton action and began to take a more active role in the uprising in November, though he firmly denied that he was one of its leaders. The Supreme Judicial Court of Massachusetts indicted 11 leaders of the rebellion as "disorderly, riotous, and seditious persons". The court was scheduled to meet next in Springfield, Massachusetts on September 26, and Shays organized an attempt to shut it down in Northampton, while Luke Day organized an attempt in Springfield.
