<P> The phrase comes from the opening stanza of Ralph Waldo Emerson's "Concord Hymn" (1837) and refers to the first shot of the American Revolution at the Old North Bridge in Concord, Massachusetts, where the first British soldiers fell in the battles of Lexington and Concord . Historically, no single shot can be cited as the first shot of the battle or the war . Shots were fired earlier at Lexington, Massachusetts where eight Americans were killed and a British soldier was slightly wounded, but accounts of that event are confused and contradictory . The North Bridge skirmish did see the first shots by Americans acting under orders, the first organized volley by Americans, the first British fatalities, and the first British retreat . </P> <P> The towns of Lexington and Concord have debated over the point of origin for the Revolutionary War since 1824, when the Marquis de Lafayette visited the towns . He was welcomed to Lexington hearing it described as the "birthplace of American liberty", but he was then informed in Concord that the "first forcible resistance" was made there . President Ulysses Grant considered not attending the 1875 centennial celebrations in the area to evade the issue . In 1894, Lexington petitioned the state legislature to proclaim April 19 as "Lexington Day", to which Concord objected; the current name for the holiday is Patriots' Day . </P> <P> Emerson lived in a house known as the Old Manse at the time when he was composing the "Concord Hymn," from which his grandfather and father (then a young child) had witnessed the skirmish . The house is located approximately 300 feet (91 m) from the North Bridge . </P> <P> The phrase "shot heard round the world" (alternatively "shots heard round the world" or "shot heard around the world") has also become associated with the assassination of Archduke Franz Ferdinand of Austria in Sarajevo on 28 June 1914, an event considered to be one of the immediate causes of World War I. Serbian Gavrilo Princip fired two shots, the first hitting Franz Ferdinand's wife Sophie, Duchess of Hohenberg, and the second hitting the Archduke himself . The death of Franz Ferdinand, heir to the Austro - Hungarian throne, propelled Austria - Hungary and the rest of Europe into World War I . </P>
