Shot heard round the world

Phrase referring to historical incidents

The "shot heard round the world" is a phrase that refers to the opening shot of the battles of Lexington and Concord on April 19, 1775, which sparked the American Revolutionary War and led to the creation of the United States. It originates from the opening stanza of Ralph Waldo Emerson's 1837 poem "Concord Hymn". The phrase has subsequently been applied to the assassination of Archduke Franz Ferdinand in 1914, a catalyst event for World War I, and hyperbolically applied to feats in sports.
