Uncle Sam Advertisement featuring Uncle Sam. Library of Congress, Washington, D.C. The origin of the term Uncle Sam, though disputed, is usually associated with a businessman from Troy, New York, Samuel Wilson, known affectionately as âUncle Samâ Wilson. The barrels of beef that he supplied the army during the War of 1812 were stamped âU.S.â to indicate government property.
So, by 1820, Uncle Sam was sometimes used as a term for the United States. The popular image of Uncle Sam did not emerge until some time later. In fact, prior to the Civil War, another character was much more commonly used as a symbol for our country; Brother Jonathan. The Cartoon above is from an original 1862 Harper's Weekly newspaper.
