Pope Clement XClement X
. Born Emilio Altieri, he was elected pope in April 1670, at the age of eighty. His years and infirmities led him to devolve the charge of the government upon his nephew, Cardinal Altieri, whose interference with the privileges of ambassadors occasioned disputes in which the Pope was obliged to yield. Little else of importance occurred during his reign, which terminated in July 1676.
