On April 19, 1775, the American Revolutionary War began with the battles at Lexington and Concord between British “Redcoats” and colonial Minutemen.
Patriots Day, the Monday nearest April 19th, is a public holiday in Massachusetts and Maine. All Massachusetts state, county and town government offices, libraries, and some local businesses close, though federal government offices, post offices, offices of large interstate and international companies, and most shops remain open.
The parade is followed by a re-enactment of the battle at Old North Bridge, commemorative ceremonies, and the repeated firing of brass cannons by the Concord Independent Battery.
