What is Uncle Sam?
Answer
A personification of the U.S. government
Explanation
Uncle Sam is a personification of the United States government, especially of the federal government and its armed services. He is depicted as a tall, lean, bearded older white man with white hair, dressed in a top hat decorated with white stars on a blue band, a red bow tie, a cutaway dark blue coat with stars, and red and white striped trousers.
The character emerged during the War of 1812 from a real person: Samuel Wilson (1766 to 1854), a meatpacker from Troy, New York, who supplied barrels of beef to the U.S. Army with the stamp U.S. branded on them. Soldiers reportedly joked that the U.S. stood for Uncle Sam, meaning Wilson, and the nickname spread through the army and into wider use. Congress passed a resolution on September 15, 1961 (House Concurrent Resolution 254 of the 87th Congress) recognizing Samuel Wilson of Troy, New York as the progenitor of America's national symbol of Uncle Sam.
The image of Uncle Sam evolved through nineteenth-century political cartoons by artists such as Thomas Nast (also known for the Republican elephant, the Democratic donkey, and the modern image of Santa Claus). The most famous version is James Montgomery Flagg's 1916 to 1917 recruiting poster I Want YOU for U.S. Army, in which Uncle Sam points directly at the viewer in front of the words I Want YOU and the legend NEAREST RECRUITING STATION below. The poster was first published as a cover of Leslie's Weekly on July 6, 1916 and was printed in over four million copies during World War I, and another 350,000 copies during World War II. Flagg modeled the figure on his own face. The poster's compositional idea was borrowed from a 1914 British recruiting poster of Lord Kitchener pointing directly at the viewer above the words BRITONS WANTS YOU.
Uncle Sam contrasts with Columbia, an earlier female personification of the country popular in the eighteenth and nineteenth centuries (Columbia appeared on coins, seals, and the dome of the U.S. Capitol), and with Lady Liberty, who appears on the Statue of Liberty in New York Harbor and on many U.S. coins. By the twentieth century, Uncle Sam had displaced Columbia as the dominant personification of the country in popular culture, particularly in connection with military recruiting, taxation (he is often shown demanding tax payment), and federal authority.
Why this matters for your test
Recognizing Uncle Sam helps applicants read American political cartoons, recruiting posters, and patriotic art. The figure is a familiar shorthand for the federal government and the U. S.
military and appears in popular culture, government communications, and civic education materials.
