St. Patrick came from a rich English family and was kidnapped by pirates to be sold as a slave in Ireland. He escaped years later but returned to tell the Irish about Jesus. There are many legends about St. Patrick such as the story of how he banished all snakes from Ireland when he arrived. He also used the Shamrock leaf to explain the Holy Trinity. St. Patrick became Ireland's first Bishop, leaving a legacy for the island to become the center of Catholic faith for centuries.
