Before he became Pope Francis, he was known as Jorge Mario Bergoglio.
The son of Italian immigrants, Bergoglio was born on December 17, 1936 in Argentina.
His father, Mario, was an accountant employed by the railways while his mother, Regina, raised the five children.
Bergoglio graduated as a chemical technician before choosing the path of the priesthood, entering the Diocesan Seminary of Villa Devoto in Buenos Aires.
He entered the Jesuit novitiate in 1958 when in his early 20s and was ordained a priest in 1969.
As Archbishop of Buenos Aires — a diocese with more than 3 million inhabitants — he created a missionary project based on communion and evangelisation.
As Pope Francis, he would become the first pope to be born or raised outside Europe since the Syrian-born Pope Gregory III in AD 731.
In 2001, he was created a cardinal under Pope John Paul II.
He asked the faithful not to journey to Rome to celebrate, but to instead donate to the poor what they would have spent on the trip.
"My people are poor and I am one of them," he said at various times, explaining his decision to live in an apartment and cook his own supper.
In 2005, he took part in the Conclave in which Pope Benedict XVI was elected.
