https://en.wikipedia.org/wiki/Pope_Clement_VII#Appearance
During his half-year imprisonment in 1527, Clement VII grew a full beard as a sign of mourning for the sack of Rome. This was in contradiction to Catholic canon law, which required priests to be clean-shaven; however, it had the precedent of the beard which Pope Julius II had worn for nine months in 1511–12 as a similar sign of mourning for the loss of the papal city of Bologna.
Unlike Julius II, however, Clement VII kept his beard until his death in 1534. His example in wearing a beard was followed by his successor, Paul III, and indeed by twenty-four popes who followed him, down to Innocent XII, who died in 1700. Clement VII was thus the unintentional originator of a fashion that lasted well over a century.
