The Franciscan Rule is a set of guidelines established by Saint Francis of Assisi in the early 13th century for the followers of his religious movement. It emphasizes living a life of poverty, humility, and simplicity, reflecting the teachings of Jesus Christ. The Rule encourages a deep connection with nature and a commitment to serving the poor and marginalized. This Rule was officially approved by Pope Innocent III in 1209, allowing the formation of the Order of Friars Minor. Over time, the Franciscan Rule has inspired various branches of the Franciscan family, including the Poor Clares and the Third Order of Saint Francis, each adapting the principles to their own contexts.
