Concord is a town in Middlesex County, Massachusetts, in the United States. At the 2010 census, the town population was 17,668. The United States Census Bureau considers Concord part of Greater Boston. The town center is near where the confluence of the Sudbury and Assabet rivers forms the Concord River.
The area that became the town of Concord was originally known as Musketaquid, an Algonquian word for "grassy plain." Concord was established in 1635 by a handful of British settlers; by 1775, the population had grown to 1,400. As dissension between colonists in North America and the British crown intensified, 700 troops were sent to confiscate militia ordnance stored at Concord on April 19, 1775. The ensuing conflict, the Battle of Lexington and Concord, was the incident that triggered the American Revolutionary War.
A rich literary community developed in Concord during the mid-19th century, centered around Ralph Waldo Emerson. Emerson's circle included Nathaniel Hawthorne, Louisa May Alcott and Henry David Thoreau. Major works written in Concord during this period include Alcott's novel Little Women, Emerson's essay Self-Reliance, and Thoreau's Walden and Civil Disobedience.
