Margaret Navarre was a pioneering figure in the French royal family, being the first to embrace the Reformation and advocate for Protestant beliefs. Educated alongside her brother, she became fluent in several languages and well-versed in various fields, including theology. Despite facing opposition from the Catholic Church and her own family, she opened the Palace of the Louvre for reformist preaching and became the first published female poet of Protestantism. Her influence extended beyond France, impacting Protestantism in England and inspiring her daughter, Jeanne. Margaret remained steadfast in her convictions until her death in 1549, leaving a lasting legacy.
