Campeggio was born in
Milan to a noble family, the eldest of five sons. Campeggio initially intended to pursue a career in law, obtaining his degree in 1499. In 1510, following the death of his wife, Campeggio began to serve the
Catholic Church. In 1511 and from 1513 to 1517, Campeggio served as nuncio on two separate occasions to
Maximilian I. In 1517, during his second period as nuncio to Maximilian I,
Leo X made him a cardinal. In 1528, Campeggio returned to England in order to hear the case for divorce between Henry VIII and
Catherine of Aragon. Due to the mental duress and his affliction with gout, this period of time was particularly unpleasant for Campeggio. Campeggio wrote his
De depravato statu ecclesiae for
Adrian VI, which proposed radical reforms for the papal bureaucracy. ==References==
