In a move that seemingly flew in the face of America's founding belief in the separation of church and state, Congress passed legislation on this day in 1908 that made the maxim "In God We Trust" an obligatory element of certain coins. The motto dates back to the early 1860s, when the Civil War stirred religious feelings throughout the nation. America's heightened piety manifested itself in many places, including the treasury department, which received countless letters requesting that the nation's coins pay some form of tribute to God. Concerned citizens and religious leaders found a fast friend in Treasury Secretary Salmon P. Chase, who readily agreed that the "trust of our people in God should be declared on our national coins." James Pollock, director of the U.S. Mint at Philadelphia, was charged with devising a suitable motto. After some key revisions from Chase, Pollock decided upon the now-familiar "In God We Trust."
