Final answer:
King Charles V signed a treaty and accepted an act of Parliament to make sure new laws were enacted.
Step-by-step explanation:
In order to make sure the new laws were enacted, King Charles V signed the secret Treaty of Dover with his cousin, Louis XIV of France. The treaty specified that England would join France in war against Holland, Charles would publicly convert to Catholicism, and the laws against Catholics in England would be relaxed. This agreement was meant to reverse 100 years of anti-Catholic legislation. However, when details of the agreement leaked out, it created anti-Catholic and anti-Charles sentiments in the nation.
Additionally, in 1673, the Test Act was passed by Parliament and reluctantly accepted by Charles. This act defined religious orthodoxy and restricted the rights of those outside of the Church of England, including Catholics, from voting, holding public office, preaching, teaching, and attending universities.
Overall, King Charles V took measures such as political treaties and acts of Parliament to ensure the enactment of new laws.
