July 30: “In God We Trust”

On this day in 1956, President Dwight D. Eisenhower signs a law officially declaring “In God We Trust” to be the nation’s official motto.

The first paper money with the phrase “In God We Trust” was not printed until 1957.

Do you know when the phrase “under God” was inserted into the pledge of allegiance?
