Evangelist preacher Billy Graham has died at the age of 99 from natural causes, The Billy Graham Evangelistic Association confirmed to NBC News.

His impact: Graham served as a spiritual advisor to roughly a dozen U.S. presidents — and he made waves in the early 1950s by forcing churches to racially integrate for his services. He preached to an estimated 200 million people in 185 countries around the world during his life, according to the association’s website.
