The paper (see Why did we adopt the constitution? Part I) that I wrote was on Shays' Rebellion. Rather than quote my old paper, I'll summarize from the web.
Shays' Rebellion "had a great influence on public opinion," as Samuel Eliot Morison notes; it was the fiercest outbreak of discontent in the early republic, and public feeling ran high on both sides. After the rebellion was defeated, the trial of the insurgents in 1787 was closely watched and hotly debated...The rebellion arose in Massachusetts in 1786, spread to other states, and culminated in an abortive attack on a federal arsenal. It wound down in 1787 with the election of a more popular governor, an economic upswing, and the creation of the Constitution of the United States in Philadelphia. Calliope Film Resources.

Shays' Rebellion had a generally unifying effect upon the supporters of a stronger national government. It provided the motivation that led to the success of the Federal Convention during the summer of 1787 and the recreation of the US under a Federally oriented constitution and the abandonment of the Articles of Confederation under which the US had originally formed.
