Irish festivals. This festival is on March 65438, 2007. It is said that St Patrick is a Christian missionary. In 422, the Pope sent him to Ireland to convert the Irish to Christianity. He went ashore from wicklow to preach, and the local heretics angrily tried to stone him to death. But he plucked a clover without fear and vividly expounded the doctrine of the trinity of the Father, the Holy Spirit and the Son, which deeply moved the Irish and made them convert to Christianity. St Patrick died on March 17, 493. In memory of him, the Irish designated this day as St. Patrick's Day. /kloc-after the 0/8th century, with a large number of Irish immigrants entering the United States, St. Patrick's Day has also become an important festival in the United States.
