Elizabeth of Portugal

Elizabeth of Aragon (1271–1336), daughter of Peter III of Aragon, became queen of Portugal by marrying King Denis in 1288. She helped shape the Treaty of Alcañices between Denis and Castile in 1297. Her son Afonso accused Denis of favouring an illegitimate son, and civil war followed.

In 1323 Elizabeth rode a mule between the opposing armies to prevent battle; peace returned in 1324 when Afonso swore loyalty to his father. She gave alms to the poor and was linked with the miracle of the roses, died at Estremoz in 1336, and was canonized by Pope Urban VIII in 1625.
