St. Patrick's Day commemorates St. Patrick, the patron saint of Ireland. According to the document, St. Patrick was born in Britain in 385 AD and was captured and enslaved in Ireland at age 16. During his captivity, he became a Christian. After escaping, he returned to Ireland and spent 30 years converting the Irish to Christianity. He established churches and schools across Ireland. St. Patrick's Day is celebrated on March 17th, the day he died, with traditions including wearing green, shamrocks, and dyeing rivers green. Leprechauns are linked to Irish folklore and spend their time making shoes and hiding pots of gold.
