The Rev. Billy Graham, who transformed American religious life through his preaching and activism, becoming a counselor to presidents and the most widely heard Christian evangelist in history, died Wednesday. He was 99.

Graham, who long suffered from cancer, pneumonia and other ailments, died at his home in North Carolina, according spokesman Mark DeMoss.

More than anyone else, Graham built evangelicalism into a force that rivaled liberal Protestantism and Roman Catholicism in the United States. His leadership summits and crusades in more than 185 countries and territories forged powerful global links among conservative Christians, and threw a lifeline to believers in the communist-controlled Eastern bloc. Dubbed "America's pastor," he was a confidant to U.S. presidents from Gen. Dwight Eisenhower to George W. Bush.'
