By 1860, Church was the most renowned American artist. In his prime, Church was a commercial as well as an artistic success. Church's art was very lucrative; he was reported to be worth half a million dollars at his death in 1900.

In 1861, at the start of the Civil War, Church was inspired to paint Our Banner in the Sky by a sunset featuring red, white, and blue that he believed was a symbol that "the heavens indicated their support for the United States by reflecting the nation's colors in the setting sun".[15] A lithograph was made from it and sold to benefit the families of Union soldiers.
