Shays rebellion convinced George Washington to join the convention because the rebellion uncovered the weaknesses of the government in managing the finances of the country.
Step-by-step explanation:
Shay's rebellion was a series of violent protests against the enforcement of local and state tax collection. The rebellion forced the lawmakers to pay attention to the Articles of Confederation and its weaknesses.
The rebellion also forced George Washington who had retired to come back into public life because he was afraid of the consequences of the rebellion and was concerned for the farmers who had lived in poverty because of poor yield.
