Saint Patrick's Day is celebrated worldwide by Irish people and increasingly by many of non-Irish descent. Celebrations are generally themed around all things green and Irish; both Christians and non-Christians celebrate the secular version of the holiday by wearing green, eating Irish food and imbibing Irish drink, and attending parades. The St. Patrick's Day parade in Dublin, Ireland is part of a five day festival, with over 500,000 people attending the 2006 parade. The largest St. Patrick's Day parade is held in New York City and it is watched by 2 million spectators. The St. Patrick's day parade was first held in New York City on 17 March 1766 when Irish soldiers marched through the city. Parades also take place in other Irish towns and villages. Other large parades include those in Cleveland, Belfast, Manchester, Birmingham, London, Coatbridge, Montreal, Boston, Chicago, Kansas City, Savannah, Pittsburgh, Denver, Sacramento, Scranton and Toronto. Large parades also take place in other places throughout Europe and the Americas, as well as Australia and Asia.
