Time magazine made him its Person of the Year in 2013, and his extraordinary popularity is credited with increasing church attendances around the world.
But a year into the job, how is Pope Francis handling the social issues affecting the Roman Catholic Church - and the scandals?
Pope Francis is the first Latin American Pontiff and the first non-European to lead the Roman Catholic Church in 1,200 years. He has been praised for his humility ahead of formality, and mercy before moralising. Supporters say he has even made being Catholic cool.
He inherited a Church facing criticism over child abuse, corruption and a raft of social issues. But will the Pontiff's gentle revolution lead to real change in the Church?
