Jorge Mario Bergoglio of Argentina was elected as the new Pope.
Pope Francis, 76, appeared on the central balcony of St. Peter's Basilica just over an hour after white smoke poured from a chimney on the roof of the Sistine Chapel to signal 115 cardinal electors had chosen him to lead the world's 1.2 billion Roman Catholics.
"Pray for me," the new pontiff, dressed in the white robes of a pope for the first time, urged the crowd, smiling warmly.
The choice of Bergoglio, who is the first Latin American and first Jesuit pope, was announced by French cardinal Jean-Louis Tauran with the Latin words "Annuntio vobis gaudium magnum. Habemus Papam" ("I announce to you a great joy. We have a pope.")
