What institution encouraged inspired and paid for the most artistic endeavors during the Middle Ages?

The Catholic Church was the primary institution that encouraged, inspired, and funded artistic endeavors during the Middle Ages. It commissioned countless works of art, including paintings, sculptures, and illuminated manuscripts, primarily for cathedrals and monasteries. This patronage not only served religious purposes but also aimed to convey theological messages and enhance the spiritual experience of worshippers. As a result, much of the era's artistic production is closely tied to the Church's influence and objectives.
