Uncle Sam originated as the personification of the United States during the British-American War of 1812. American folklore claims that the appearance of the expression "Uncle Sam" is associated with the butcher Samuel Wilson, who supplied provisions to the American army. Wilson labeled the meat barrels with the letters U.S., meaning the United States, and the soldiers joked that the meat came from Uncle Sam. On March 13, 1852, the New York newspaper NY Lantern Weekly published what is believed to be the first image of Uncle Sam.
The traditional image was mainly created by the artist Thomas Nast in a series of political cartoons published in the second half of the 19th century. Often he was portrayed as a tall elderly man with thin, determined features, an old-fashioned beard, a top hat in the colors of the American flag, a blue tailcoat and striped trousers.
The image of Uncle Sam gained particular prominence during the First World War. Then Uncle was depicted on a poster inviting volunteers to join the American army and take part in the war in Europe. From the poster, Uncle Sam looked sternly and pointed at the reader with his finger, and the caption under the picture read "I need you in the United States Army." army pushed Dmitry Moor to the idea of the famous poster from the Civil War in Russia "Have you signed up as a volunteer?"
On September 15, 1961, the 87th United States Congress passed a resolution glorifying "Uncle Sam" Wilson as the prototype of Uncle Sam. There is even a memorial monument at Wilson's birthplace in Arlington, Massachusetts. The grave of Sam Wilson is located in Troy (New York).
