Step-by-step explanation:
The two main religions during this time period were Catholicism and Protestantism. Catholicism was the dominant branch of Christianity, with its roots in Western Europe and the Roman Catholic Church being the primary organization. Protestantism emerged later, at the beginning of the sixteenth century, as a result of the Protestant Reformation led by figures like Martin Luther.
Protestantism brought about a break with the Roman Catholic Church and different forms of Protestant churches emerged throughout Europe. However, Catholicism remained the predominant religion in many areas, including Spain.
