This painting is called the execution of King Charles I of England in 1649. In the painting Charles I is being beheaded after a conflict between the Roundheads (parliament) and the Cavaliers (royalists). After Charles I is beheaded all of Europe is struck with terror. Charles I was said to be executed due to treason. He was said to have alienated both the parliament and his subjects. Also his marriage to Henrietta Maria left ambiguity in his protestant subjects. This is because Henrietta Maria was a Roman Catholic.
After the death of Charles I the monarchy is abolished by parliament and declared England a “common wealth.” Therefore the death of Charles I had a negative impact on the empire because after Cromwell died there was no one to succeed him. In the restoration the empire becomes a monarchy and is ruled by James II.
