Pope Alexander VIII (b. 1610)
Pope Alexander VIII (Italian: Alessandro VIII; 22 April 1610 – 1 February 1691), born Pietro Vito Ottoboni, was head of the Catholic Church and ruler of the Papal States from 6 October 1689 to his death in 1691. He is to date the last pope to take the pontifical name of "Alexander" upon his election to the papacy.
Alexander VIII is known for having overturned many of the policies of his predecessor, Innocent XI, deciding to indulge in nepotism in order to further enrich his family. Such nepotism exhausted the papal treasury, later forcing his successor, Innocent XII, to implement austere measures to restore the papal coffers. Despite his brief papacy, during which little of importance was undertaken, Alexander VIII is known for having condemned the doctrines of the so-called philosophical sin which was being taught in schools run by the Society of Jesus. Also during his papacy, King Louis XIV of France restored Avignon to the Holy See as a territory of the Papal States.
