What experiences caused Americans to reject monarchy and unitary government?

The events and experiences that caused Americans to reject monarchy and unitary governments were the various measures taken by the British Crown since the end of the French and Indian War, which included raising taxes on settlers, restricting economic freedoms. to them and, especially, the sanction of the Intolerbable Acts, which were passed as punishment by the Boston Tea Party, limiting to the extreme the civil, political and economic liberties of the colonists.
