Daniel Shays was a leader of protests primarily over the failure of the US government to pay back wages it owed to thousands of veterans of the revolutionary war. It is important because it pointed out the glaring deficiency of Congress under the Articles of Confederation. The protests lasted several months, disrupting various forms of government.

Shays' Rebellion is important because it was the catalyst to organize a Constitutional Convention to create a stronger federal government. As my history professor liked to say, "It's not what it is, it is what it represents."

Let me pontificate here--Daniel Shays was the leader so the apostrophe comes after the s not before. Ain't grammar a hoot.

It is a spelling thing, not a grammar thing.
