Antonio Margil was a Spanish Franciscan missionary who dedicated his life to serving indigenous populations throughout North and Central America. Born in Valencia in 1657, he joined the Order of Friars Minor before traveling to the Americas in 1683. He was primarily based at the College of Santa Cruz de Querétaro, but his extensive travels took him through regions such as Guatemala, Texas, and Louisiana. Known for his rigorous asceticism, he practiced constant prayer and frequent fasting while traversing vast territories to establish numerous missions.
