Answer:
Yes, he was right in what he did.
Explanation:
Daniel Shays was right in what he did because he helped lead a movement against the oppressive government. Furthermore, his rebellion proved to the government that the Articles of Confederation was a weak document and ineffective because they could not stop his rebellion. As a result, they revised the Articles and eventually created the Constitution, which is an important document that is still used today. Without Shay's Rebellion, that may have never happened. Also, sometimes rebellions and uprisings are necessary to bring change. There are many examples of uprisings bringing change throughout history, such as Martin Luther King Jr's marches and protests, and even the protests going on today. Therefore, I think Daniel Shays was right in what he did because he helped fight against unfair taxation and his rebellion led to the Constitution being created.
