Jorge Mario Bergoglio was born on 17 December 1936 in Flores, a neighborhood of Buenos Aires.

Bergoglio studied at the archdiocesan seminary, Inmaculada Concepción Seminary, in Villa Devoto, Buenos Aires, and, after three years, entered the Society of Jesus as a novice on 11 March 1958.

At the conclusion of his novitiate in the Society of Jesus, Bergoglio officially became a Jesuit on 12 March 1960, when he made the religious profession of the initial, perpetual vows of poverty, chastity and obedience of a member of the order.

In 1967, Bergoglio finished his theological studies and was ordained to the priesthood on 13 December 1969, by Archbishop Ramón José Castellano.

Bergoglio completed his final stage of spiritual training as a Jesuit, tertianship, at Alcalá de Henares, Spain. He took the final fourth vow (obedience to the pope) in the Society of Jesus on 22 April 1973.

Bergoglio was named Auxiliary Bishop of Buenos Aires in 1992 and ordained on 27 June 1992 as Titular Bishop of Auca, with Cardinal Antonio Quarracino, Archbishop of Buenos Aires, serving as principal consecrator.

On 3 June 1997, Bergoglio was appointed Coadjutor Archbishop of Buenos Aires with right of automatic succession.

At the consistory of 21 February 2001, Archbishop Bergoglio was created a cardinal by Pope John Paul II with the title of cardinal priest of San Roberto Bellarmino, a church served by Jesuits and named for one; he was formally installed in that church the following 14 October.

On 8 November 2005, Bergoglio was elected president of the Argentine Episcopal Conference for a three-year term (2005–08).

He was reelected to another three-year term on 11 November 2008.

When he turned 75 in December 2011, Bergoglio submitted his resignation as Archbishop of Buenos Aires to Pope Benedict XVI as required by canon law.

Bergoglio was elected pope on 13 March 2013, the second day of the 2013 papal conclave, taking the papal name Francis.

At his first audience on 16 March 2013, Francis told journalists that he had chosen the name in honor of Saint Francis of Assisi, and had done so because he was especially concerned for the well-being of the poor.

On 31 March 2013, Francis used his first Easter homily to make a plea for peace throughout the world, specifically mentioning the Middle East, Africa, and North and South Korea.

In May 2013, Pope Francis met with Pope Tawadros II of Alexandria in the Vatican. The meeting coincided with the 40th anniversary of the first visit by a Pope of the Coptic Orthodox Church of Alexandria to the Vatican; when Pope Shenouda III of Alexandria met with Pope Paul VI on 10 May 1973.

On 29 June 2013, Pope Francis published his first encyclical, titled Lumen fidei.

The pope has also continued the practice of having beatifications celebrated in the place of the individual's origin though has presided over beatifications himself on three occasions for Paul Yun Ji-Chung and 123 companions on 16 August 2014, his predecessor Pope Paul VI on 19 October 2014 and two Colombian martyrs on 8 September 2017.

On 12 May, Francis carried out his first canonizations of candidates approved for sainthood during the reign of Benedict XVI: the first Colombian saint, Laura of Saint Catherine of Siena, the second female Mexican saint, Maria Guadalupe Garcia Zavala, both of the 20th century, and the 813 15th-century Martyrs of Otranto.

On 18 June 2015, Pope Francis issued a papal encyclical called Laudato si' on climate change, care for the environment, and sustainable development. The encyclical, although dated 24 May 2015, was officially made public on 18 June 2015.

In June 2015, Pope Francis met with Moran Mor Ignatius Aphrem II, Patriarch of the Syriac Orthodox Church.

On the October 16, 2017 World Food Day ceremony, held at the Food and Agriculture Organization (FAO), which is headquartered in Rome, Pope Francis called for collaboration among world leaders to assure food security which requires tackling the "root of problem" of food insecurity. Pope Francis cited "studies conducted by the United Nations and many other civil society organisations" that said the "two main obstacles to overcome" are "conflicts and climate change".

On 8 December 2017, Pope Francis signed a new apostolic constitution on ecclesiastical universities and faculties Veritatis gaudium, published 29 January 2018.

At the first consistory of his papacy, held on 22 February 2014, Francis created 19 new cardinals. At the time of their elevation to that rank, 16 of these new cardinals were under eighty years of age and thus eligible to vote in a papal conclave.
