Factbox-Pope Francis: Key moments from his life

VATICAN CITY (Reuters) - Here are some facts about Pope Francis, who has died at the age of 88.

- Jorge Mario Bergoglio was born on December 17, 1936, in Buenos Aires, Argentina, of Italian immigrant stock. He was ordained a priest in the Jesuit order in 1969. From 1973-79 he was the order's top leader in Argentina. He became an auxiliary bishop of Buenos Aires in 1992 and the city's archbishop in 1998. He was made a cardinal in 2001 by Pope John Paul II.

   - Surprising many observers of the Roman Catholic Church, Bergoglio was elected pope at a conclave in March 2013 following the resignation of Pope Benedict. He chose to be called Francis in honour of Saint Francis of Assisi, emphasising a commitment to poverty, peace, and care for the environment.

- He was the first non-European pope in 1,300 years, the first from Latin America and the first Jesuit to hold the post. Jesuits are known for their commitment to education and social justice, including working with the poor and marginalised.

- He shunned many of the traditional trappings of the papacy, preferring to live in a modern Vatican guest house rather than the grand papal apartments in the Apostolic Palace. He pared back the papal wardrobe, wore a plastic watch and chose to be driven around in a simple family car.

   - He soon clashed with conservatives, who were unhappy with his informal style from the start. They balked at his calls for the Church to be more welcoming to LGBT people and divorced Catholics and at his clampdowns on the use of the traditional Latin Mass.

- Francis made 47 trips outside of Italy, visiting more than 65 states and territories, clocking up more than 465,000 km (289,000 miles). However, he never returned to Argentina. 

- He initiated changes within the Vatican, emphasizing transparency, accountability and financial reform, and appointed more women to senior posts in its hierarchy. However, he was also viewed as a haphazard leader, often blindsiding Vatican officials with his off-the-cuff comments and unpredictability. Despite many efforts, he struggled to get a grip on the Church's crisis over sexual abuse by clerics.
