E pluribus unum (Latin for "Out of many, one" (alternatively translated as "One out of many" or "One from many") is a thirteen letter phrase on the Seal of the United States, along with Annuit cœptis (Latin for "He approves (has approved) of the undertakings") and Novus ordo seclorum (Latin for "New Order of the Ages"), and adopted by an Act of Congress in 1782. Never codified by law, E Pluribus Unum was considered a de facto motto of the United States until 1956 when the United States Congress passed an act (H. J. Resolution 396), adopting "In God We Trust" as the official motto.

It has been understood that the traditional meaning of the phrase is that out of many states (or colonies) emerges a single nation. However, in recent years its meaning has come to suggest that out of many peoples, races, religions, languages, and ancestries has emerged a single people and nation. All the citizens in the country make the nation great.

Today, in America, this motto is still viewed as highly important. The 13 letters of the phrase, E pluribus unum, appear on all coins currently being manufactured, including the Presidential dollars that started being produced in 2007, where it is inscribed on the edge along with "In God We Trust" and the year and mint mark. The specific motto E pluribus unum was first used by the U.S. Treasury on coinage in 1795, when the reverse of the half eagle (5 dollar gold) coin presented the main features of the Great Seal of the United States.
