In 1956, the nation was at a particularly tense time in the Cold War, and the United States wanted to distinguish itself from the Soviet Union, which promoted state atheism. As a result, the 84th Congress passed a joint resolution "declaring IN GOD WE TRUST the national motto of the United States." The law was signed by President Eisenhower on July 30, 1956, and the motto was progressively added to paper money over a period from 1957 to 1966. (Public Law 84-851) The United States Code at 36 U.S.C. § 302, now states: "'In God we trust' is the national motto."
