Pope Benedict XVI
On 11 February 2013, Benedict announced his resignation in a speech in Latin before the cardinals. His reason was a "lack of strength of mind and body" because of his old age. His resignation became effective on 28 February 2013. He was the first pope to resign since Pope Gregory XII in 1415. He was the first to resign by choice since Pope Celestine V in 1294. As Pope Emeritus, Benedict retains the style of His Holiness, and the title of Pope. He will continue to dress in the papal colour of white. He was succeeded by Pope Francis on 13 March 2013. He moved into the newly renovated Mater Ecclesiae monastery for his retirement on 2 May 2013. In September 2020, Benedict XVI became the longest-lived pope at aged 93.
