The superior general of the Society of Jesus is the leader of the Society of Jesus, the Catholic religious order also known as the Jesuits. He is generally addressed as Father General. The position sometimes carries the nickname of the Black Pope, because of his responsibility for the largest male religious order, in contrast with the white garb of the pope. The thirty-first and current superior general is Fr Arturo Sosa, elected by the 36th General Congregation on 14 October 2016.
