"In God We Trust" (also rendered as "In God we trust") is the official motto of the United States, the U.S. state of Florida, and the nation of Nicaragua (Spanish: En Dios confiamos). It was adopted by the U.S. Congress in 1956, via a joint resolution, replacing E pluribus unum ("Out of many, one"), which had been the de facto motto since the initial design of the Great Seal of the United States.
The fourth stanza of the U.S. national anthem "The Star-Spangled Banner", adopted from the 1814 poem "The Defence of Fort M'Henry", contains the line: "And this be our motto—"In God is our trust"". The origins of "In God We Trust" as a political motto lie in the American Civil War, where Union supporters wanted to emphasize their attachment to God and to boost morale.
