Final answer:
Some monarchs found Protestantism attractive due to power, wealth, and nationalism.
Step-by-step explanation:
Some monarchs in Europe during the 16th, 17th, and 18th centuries found Protestantism attractive for reasons beyond spiritual belief. One of the main reasons was power. Protestantism allowed monarchs to challenge the authority of the Catholic Church and establish their own religious authority, making them less dependent on the Pope.
Another reason was wealth. Monarchs who supported Protestantism could seize the Catholic Church's land and wealth, increasing their own power and resources. Additionally, Protestantism was often associated with nationalism, which appealed to monarchs seeking to consolidate their territories and strengthen their kingdoms.
