Jorge Mario Bergoglio elected new Pope

Newly elected Pope Francis, Cardinal Jorge Mario Bergoglio of Argentina leaves after praying at the Santa Maria Maggiore Basilica in Rome.

Francis will celebrate his first Mass as pope in the Sistine Chapel on Thursday, and will be installed officially as pope on Tuesday, according to the Vatican spokesman the Rev. Federico Lombardi.

Latin Americans reacted with joy on March 13 at news that the Argentine Cardinal Jorge Mario Bergoglio was elected pope. Bergoglio, who chose the name Pope Francis, is the first pope ever from the Americas.

Looking stunned, Francis shyly waved to the crowd of tens of thousands of people who gathered in St. Peter's Square for the announcement, marveling that the cardinals needed to look to "the end of the earth" to find a bishop of Rome.

Jorge Mario Bergoglio chose the name Francis, associating himself with the humble 13th-century Italian preacher who lived a life of poverty.
