St. Martin of Tours was a 4th-century Christian bishop known for his compassion and dedication to helping the poor. Born in what is now Hungary, he became a soldier before converting to Christianity. One of the most famous stories about him involves sharing his cloak with a beggar during a cold winter, which later led to a vision of Christ. He is the patron saint of France and soldiers, and his feast day is celebrated on November 11. St. Martin's legacy includes the establishment of monastic communities and the spread of Christianity throughout Europe. His life exemplifies the values of charity and humility.
