There are several versions of the story of Uncle Sam. Where do symbols like these come from? The official version, confirmed by Congress in 1961, dates Uncle Sam back to the War of 1812. Each symbol personifies the government in a different way: the fatherly, sometimes overbearing Uncle Sam; the oppressive, snooping Big Brother of \"1984\" fame; and the spirited, industrious Yankee Doodle. Despite shifting times and numerous parodies, Uncle Sam remains a powerful symbol of patriotism and the American government.
