The Waldensians were a religious group that originated in the 12th century in the French Alps. They were also known as the Vaudois or the Valdenses. Other synonyms for the term Waldensians include the Waldenses, the Petrobrusians, the Henricians, and the Insabbati. These groups were originally founded by Peter Waldo, an affluent merchant who gave up his wealth to become a preacher and spread the gospel. The Waldensians faced persecution from the Roman Catholic Church and were forced to leave their homes and flee to other parts of Europe. They were known for their simplicity of life, adherence to scripture, and commitment to spreading the word of God.
