Born in Iowa in 1862, Sunday's life was marked by hardship and loss, but he found solace in Christianity after attending an evangelical rally. He went on to become a prominent preacher, leading numerous crusades and converting millions of people to Christianity. Sunday's influence paved the way for other notable evangelists, including Billy Graham, and his legacy continues to be felt in American history.
