Answer: A. King Charles’s his efforts to uphold the petition of right lead to a bloody Civil War between the King and supporters of Parliament.
The petition of right was part of the massive conflict between the Stuart Monarchy and the English parliament. This led to the war of the Three Kingdoms. This war involved the kingdoms of England, Ireland, and Scotland all ruled by the same king; King Charles I.
This war ended with the parliamentarian army of the English parliament defeating all belligerents, the abolition of the monarchy, the founding of the Commonwealth of England, and the execution of the King. This war began due to disputes regarding the ultimate political power held by King Charles I. After the war, the Commonwealth was formed and the Kingdom of Ireland and Scotland began being ruled by military governors.
