Uncle Sam is a superhero appearing in American comic books published by DC Comics. Based on the national personification of the United States, Uncle Sam, the character first appeared in National Comics #1 (July 1940) and was created by Will Eisner. Publication history Quality Comics Uncle Sam first appeared in National Comics #1 (July 1940), which was published by Quality Comics during the Golden Age of Comic Books. He was depicted as a mystical being who was originally the spirit of a slain patriotic soldier from the American Revolutionary War, and who now appears in the world whenever his country needs him. The character was used for a few years from 1940 to 1944, briefly receiving its own series, Uncle Sam Quarterly. During this time, he had a young, non-costumed sidekick named Buddy Smith. According to Jess Nevins' Encyclopedia of Golden Age Superheroes, "he fights a variety of Axis agents, human and superhuman, from the Black Legion to the shrink-ray-wielding Professor Nakajima. Uncle Sam also fights the mad scientist Dr. Dirge, the King Killer, and the insanity-causing Mad Poet". DC Comics DC Comics acquired the character as part of its acquisition of the Quality characters in the 1950s, and he was used as a supporting character in Justice League of America in the 1970s. This established Uncle Sam as the leader of the Freedom Fighters, a team of former Quality characters that briefly received its own title. This team was initially based on a parallel world called Earth-X, where World War II had lasted into the 1970s. Uncle Sam's origin was rewritten somewhat in The Spectre, where Uncle Sam is described as a spiritual entity created through an occult ritual by the Founding Fathers. This "Spirit of America" was initially bound to a powerful talisman and would take physical form by merging with a dying patriot. The new origin states that the Spirit of America had taken human form as the Minute-Man during the Revolutionary War, Brother Jonathan in later conflicts and, during the American Civil War, had been split in two as Johnny Reb and Billy Yank. The Spirit first assumed its now-familiar Uncle Sam incarnation in 1870, when it resurrected a political cartoonist who had been killed by Boss Tweed. The second host of Uncle Sam fought in World War I. A third (the character's Golden Age incarnation) was a superhero during World War II but vanished at
