About the author

Bartolomeo Alberto Cappellari reigned as Pope Gregory XVI from 2 February 1831 to his death in 1846. He is the most recent pope to take the pontifical name "Gregory", and the most recent non-bishop to become pope. Strongly conservative and traditionalist, he opposed modernising reforms in the Papal States and throughout Europe, seeing them as fronts for revolutionary leftism.
