Concord, a small country town about 15 miles northwest of Boston, was where the colonial American militia stockpiled their guns and ammunition in the months preceding the outbreak of the Revolutionary War. The British attempted a surprise attack on the weapon stores in Concord on the night of April 18, 1775.
The colonials had already anticipated this, and on the first sign of British movement Paul Revere, Samuel Prescott and William Dawes rode ahead of the British armies to spread the word. American defenders gathered in Concord and Lexington, and the result was a rout of the British forces and a major victory for the cause of American independence.
Two generations later, a literary and philosophical revolution began in the same town. Ralph Waldo Emerson, Margaret Fuller, Bronson Alcott and other progressive thinkers began holding meetings to discuss anti-slavery activism, spirituality, education and the idea of a uniquely American sense of art. They founded a literary journal called "The Dial" to help spread the word, and New England Transcendentalism was born.
