What is Patriots' Day?
Patriots' Day is a state holiday observed on the third Monday of April in Massachusetts and Maine. It commemorates the Battles of Lexington and Concord on April 19, 1775 — the first military engagements of the American Revolutionary War.
This holiday should not be confused with Patriot Day (September 11), which commemorates the 9/11 attacks. Patriots' Day (plural, with apostrophe) is specifically about the start of the American Revolution.
The battles at Lexington and Concord marked the moment when colonial resistance turned into open armed conflict against British rule. The famous phrase \"the shot heard round the world\" refers to the first shots fired at the North Bridge in Concord, signaling the beginning of the fight for American independence.
Patriots' Day is also famous for being the day of the Boston Marathon, the world's oldest annual marathon, which has been held on this day since 1897.

History & Origin
On the night of April 18, 1775, Paul Revere, William Dawes, and Samuel Prescott set out on their famous midnight ride to warn the colonial militia that British troops were marching from Boston to seize military supplies stored in Concord.
At dawn on April 19, 1775, about 700 British soldiers arrived at Lexington Green, where they encountered approximately 77 minutemen led by Captain John Parker. Shots were fired — the famous \"shot heard round the world\" — and eight minutemen were killed. The British then marched to Concord, where they faced a larger force of militia at the North Bridge. The colonists forced the British to retreat back to Boston, harassing them along the entire route.
Patriots' Day was originally observed on April 19, the actual anniversary of the battles. In 1969, it was moved to the third Monday in April to create a long weekend. Massachusetts has observed the holiday since 1894, and Maine adopted it as a state holiday as well.
The Boston Marathon has been run on Patriots' Day since its inaugural race in 1897, making it one of the most iconic annual traditions associated with the holiday.
