Argentina's Jorge Bergoglio, elected on Wednesday to lead the world's Roman Catholics, is a humble rail worker's son who became a Jesuit priest and who is seen as true to his working-class roots.
At 76, Bergoglio -- Latin America's first pope -- still has a reputation as an ascetic despite his archbishop's robes. He rides clattering city buses, makes his own meals and is famously accessible.
Bergoglio's choice of the papal name Francis, also a first, was seen as a highly non-traditional choice as it honors a saint known for stressing humility.
The name is in line with his reputation, and he is seen in Argentina as ideologically mainstream, while his Society of Jesus is regarded as being among the most progressive Church institutions, especially in education.
Sergio Rubin, religious writer for the Buenos Aires newspaper Clarin, said that, like Pope John Paul II, Bergoglio is "conservative at the level of doctrine, and progressive on social issues."
For example, he has hit out sharply at the International Monetary Fund and at modern market capitalism.
Even so, Rubin acknowledged that Bergoglio's rejection of liberation theology remains controversial among left-leaning Argentines and Catholics.
Those who know him describe the Archbishop of Buenos Aires and primate of Argentina as a shy, softly-spoken man who shuns high society.
He was born December 17, 1936 to a rail worker who emigrated from northern Italy and a housewife.
The new pontiff went to a state-run school and studied to become a chemical technician.
When he graduated at 22, he joined the Jesuits and took a degree in philosophy. He followed this with theology studies and was ordained in 1969.
He was only 36 when he was named to lead Argentina's Jesuits, a job he held for six difficult years under the country's military dictatorship.
Bergoglio battled to prevent Jesuits from joining the liberation theology movement, which drew many of the continent's Catholic priests into political activities challenging right-wing governments.
His spokesman Guillermo Marco recalled that he issued a simple order: "Maintain the non-politicization of the Society of Jesus."
Bergoglio's position was in line with that of John Paul II, who after becoming pope in 1978 directed a campaign to repress liberation theology.
In the 1980s Bergoglio studied for a doctorate in Freiburg, Germany, after which he returned to become a parish priest in Cordoba.
His ascent in the Catholic hierarchy began when in May 1992 Pope John Paul II named him assistant bishop of Buenos Aires. By 1998 he was archbishop of Buenos Aires and, three years later, a cardinal.
His reputation grew among bishops after he stepped in to produce the final report of the Church's October 2001 Synod when New York Archbishop Edward Egan was prevented from the task by the September 11 terrorist attacks.
A great student of writers Jorge Luis Borges and Fyodor Dostoyevsky, he rises at 4:30 am and is known to have little social life. Unlike most Argentines, he goes to bed at 9:00 pm.
