Explanation: First of all, the Renaissance began as a cultural movement in the 14th century, but the roots and influence of the Renaissance were much deeper. In translations, it means rebirth, and represents a newborn of the classic art of ancient Greece, but also a glance at the world at all. Humanism and naturalism as the basic ideas of Renaissance art, but also of science and life in general, contradicted church doctrine and dogma. This resulted in the conversion from ecclesiastical dogmas and favouring human and natural laws as the primary, and in this way weakened the influence of the church.
Thank you for posting your question in Brainly. I hope my answer is satisfactory to you.
One reason the Catholic church became less powerful in the 14th-15th century is due to the rise of a new religion that contradicted it's beliefs, and offered more than Catholic rituals. Protestantism was the religion that caused the Catholics to weaken in power. It was promoted by England and other European entities. Because of this, influence of the Vatican diminished.
