Uncle Sam is a national personification of the United States, commonly used to represent the federal government or the country as a whole. The figure became widely associated with American patriotism in the 19th century and was popularized by wartime propaganda, especially James Montgomery Flagg’s 1917 recruiting poster.

Origins

Uncle Sam is commonly traced to Samuel Wilson, whose name was jokingly connected to army provisions marked “U.S.” during the War of 1812. The nickname gradually came to stand for the United States government.

Visual depiction

By the late 19th and early 20th centuries, cartoonists had standardised Uncle Sam’s appearance as a white-haired man with a goatee, striped trousers, and a star-spangled hat. This image became especially famous through James Montgomery Flagg’s First World War recruiting poster.

Use in politics and culture

Uncle Sam has appeared widely in political cartoons, recruitment campaigns, and commentary on U.S. policy. The symbol is used both sincerely as a patriotic image and critically as a representation of American power.

Official recognition

Although the figure long existed in popular culture, the U.S. Congress passed a resolution in 1961 saluting Samuel Wilson as the progenitor of Uncle Sam. This did not create the symbol, but it formally acknowledged the traditional association.
