Soldiers in the War of 1812 created Uncle Sam, the popular nickname for the United States.
In 1813, the United States gets its nickname, Uncle Sam. The name is linked to Samuel Wilson, a meat packer from Troy, New York, who supplied barrels of beef to the United States Army during the War of 1812. Wilson (1766-1854) stamped the barrels with "U.S." for the United States, but soldiers began referring to the grub as "Uncle Sam's." The local newspaper picked up on the story and Uncle Sam eventually gained widespread acceptance as the nickname for the U.S. federal government.
In the late 1860s and 1870s, political cartoonist Thomas Nast (1840-1902) began popularizing the image of Uncle Sam. Nast continued to evolve the image, eventually giving Sam the white beard and stars-and-stripes suit that are associated with the character today.
