St. Catherine was a third-order Dominican, peacemaker and counselor to the Pope. She singlehandedly ended the Avignon exile of the successors of Peter in the 14th century. She is the co-patron of Italy and of Europe. Great political acts which are attributed to her include achieving peace between the Holy See and Florence who were at war, to convince the Pope to return from his Avignon exile, which he did in 1376, and to heal the great schism between the followers of the legitimate Pope, Urban VI, and those who opposed him in 1380. She achieved this while on her deathbed. Her Dialogues, one of the classics of Italian literature, are the record of her mystical visions which she dictated in a state of mystical ecstasy. She died in Rome on April 29, 1380, at the age of 33.
