Final answer:

Step-by-step explanation:
The Catholic Church had a major influence in Europe during the medieval period.
Beginning with the reform efforts of Martin Luther and John Calvin in the 16th century, Catholic dominance came under attack as the Protestant Reformation began, resulting in a split among European Christians.
During the English Civil War, the side that wanted new taxes to crush rebellion in Scotland and violated provisions of the Petition of Right was the Royalist side, which was aligned with the Catholic Church.
