United States Makes 'In God We Trust' Its National Motto – July 30, 1956
This week marks the anniversary of when United States President Dwight D. Eisenhower signed a law making the statement "In God We Trust" the national motto.
Having signed a law that placed "In God We Trust" on national coins the year before, President Eisenhower signed P.L. 84-140, which also mandated that the motto be on paper money.
"The first paper money with the phrase "In God We Trust" was not printed until 1957," explained History.com.
"Since then, religious and secular groups have argued over the appropriateness and constitutionality of a motto that mentions 'God,' considering the founding fathers dedication to maintaining the separation of church and state."
