"Pope Alexander VII (13 February 1599 – 22 May 1667), born Fabio Chigi, was Pope from 7 April 1655 to his death in 1667.
He began his career as ...
a vice-papal legate, and he held various diplomatic positions in the Holy See. He was ordained as a priest in 1634, and he became Bishop of Nardo in 1635. He was later transferred in 1652, and he became Bishop of Imola. Pope Innocent X made him Secretary of State in 1651, and in 1652, he was appointed as a Cardinal.
Early in his papacy, Alexander, who was seen as an anti-Nepotist at the time of his election, lived simply; later, however, he gave jobs to his relatives, who eventually took over his administration." - (en.wikipedia.org 21.09.2019)
