What was the role of the church in medieval Europe?

The Roman Catholic Church had a huge impact during the Middle Ages. It united all the people who lived in Europe during the Middle Ages. Kings were dedicated to protecting religion and the Roman Catholic Church during the Middle Ages. Across the continent, people contributed a lot to the church — they were expected to contribute tithes — about 10% of their income. The Church in the Middle Ages was completely exempt from paying taxes, and it also became the most powerful institution in the world. All medieval people believed in the concept of Heaven and Hell.
