E Pluribus Unum

National Motto, 1782-1956

America’s first national motto, E Pluribus Unum—Out of many, one—expresses the ideal of our Union: many states, one nation. Representing all of the states, Congress has promoted national unity through a process of inquiry, debate, compromise and consensus. These documents record the continuing legislative efforts to establish, grow and maintain one nation.
