Pope Benedict XVI
Benedict XVI, born Joseph Alois Ratzinger on 16 April 1927, was the 265th Pope, by virtue of his office of Bishop of Rome, the head of the Catholic Church and, as such, Sovereign of the Vatican City State from 2005 to 2013. Although a distinguished university theologian who in his adolescent years was conscripted into the Hitler Youth and subsequently the German anti-aircraft corps and who lost a cousin to the Nazi eugenics program, he is generally not regarded as being as awesome as his predecessor.
On 11 February 2013, Pope Benedict announced his resignation, citing "lack of strength of mind and body". He formally retired February 28 to become pope emiritus, the first since Pope Gregory XII in 1415, and the first pope to retire of his own initiative since Pope Celestine V in 1294. He is succeeded by Pope Francis I.
