"In God We Trust" is the official motto of the United States as well as the motto of the U.S. state of Florida, along with the nation of Nicaragua. It was adopted by the U.S. Congress in 1956, replacing E pluribus unum, which had been the de facto motto since the initial design of the Great Seal of the United States.

E pluribus unum – Latin for "Out of many, one" – is a traditional motto of the United States, appearing on the Great Seal along with Annuit cœptis and Novus ordo seclorum which appear on the reverse of the Great Seal; its inclusion on the seal was suggested by Pierre Eugene du Simitiere and approved in an act of the Congress of the Confederation in 1782. While its status as national motto was for many years unofficial, E pluribus unum was still considered the de facto motto of the United States from its early history. Eventually, the U.S. Congress passed an act in 1956, adopting "In God We Trust" as the official motto.
