At 16, Maewyn was captured and sold into slavery by a group of pirates who raided his village. After six years of herding sheep, Maewyn escaped, went to France and became a priest, adopting the name Patrick.

During his training, Patrick discovered that his calling was to convert Irish pagans to Christianity. He returned to Ireland, established monasteries across the country, set up schools and churches, and converted many with his winning personality. Patrick carried on a very successful mission for thirty years. When he died on March 17, that day was commemorated as St. Patrick's Day.

Originally a Catholic holy day, St. Patrick's Day has evolved into more of a secular holiday. In America, in fact, St. Patrick's Day is basically a time when everyone becomes Irish, wears green and goes out to party.
