St. Francis of Assisi was an Italian religious leader born in 1181. He is best known for founding the Franciscan Order, which emphasizes a life of poverty, humility, and service to others. St. Francis had a deep love for nature and animals, often referring to them as his brothers and sisters. His teachings focused on living simply and caring for the environment. In 1224, St. Francis received the stigmata, marking him as one of the first known individuals to bear the wounds of Christ. He died in 1226 and was canonized as a saint by Pope Gregory IX in 1228. His feast day is celebrated on October 4th.
