General Lew Wallace had lived a colorful life of his own before his novel Ben-Hur: A Tale of the Christ was published in 1880. By then, he had defended Washington, D.C. from Confederates during the Civil War, served on the court-martial that tried Lincoln’s assassins, and, as Governor of New Mexico Territory, dealt with outlaws like Billy the Kid.
But what he really wanted to do was write — and so he wrote his novel about a Jewish prince who is betrayed by a Roman tribune during the time when Jesus lived. Ben-Hur was spurred by Wallace’s love of stories like The Count of Monte Cristo, but it was also motivated by an encounter with Robert Ingersoll, a famous agnostic who was passionately opposed to Christianity. Until then, Wallace had been indifferent towards religion, but afterwards, he felt he needed to research Christianity for himself — and thus became a believer.
