What was the relationship between Shays' Rebellion and the calling of the Constitutional Convention?

The relationship between these two events is that Shays's
Rebellion led to the calling of the Constitutional
Convention.

Shays's Rebellion was a call for the
Massachusetts state government to make laws that helped out poor farmers in debt.  Many
other states had made such laws already.  The rich in America at the time were very
worried by such laws.  They were worried by the fact that states had been passing such
laws.  This made them want a new system of government in which the states would have
less power.  Because they wanted a new system like that, they called the Constitutional
Convention.
