Denis, too, was the object of many of her peace endeavors. Elizabeth long sought peace for him with God, and was finally rewarded when he gave up his life of sin. She repeatedly sought and effected peace between the king and their rebellious son Alfonso, who thought that he was passed over to favor the king’s illegitimate children. She acted as peacemaker in the struggle between Ferdinand, king of Aragon, and his cousin James, who claimed the crown. And finally from Coimbra, where she had retired as a Franciscan tertiary to the monastery of the Poor Clares after the death of her husband, Elizabeth set out and was able to bring about a lasting peace between her son Alfonso, now king of Portugal, and his son-in-law, the king of Castile.

Reflection

The work of promoting peace is anything but a calm and quiet endeavor. It takes a clear mind, a steady spirit and a brave soul to intervene between people whose emotions are so aroused that they are ready to destroy one another. This is all the more true of a woman in the early 14th century. But Elizabeth had a deep and sincere love and sympathy for humankind, an almost total lack of concern for herself, and an abiding confidence in God. These were the tools of her success.
