Catherine was born in Siena in modern day Italy in 1347. She decided at a young age to devote her life to God even though her parents disapproved. Shortly after making her vows, she became a Stigmatic and experienced mystical marriage. During the time when Florence was at war against the Pope, Catherine acted as an ambassador of Florence and played a role in convincing Pope Gregory XI to leave Avignon for Rome. She was the first woman to be declared "doctor of the Church" and was canonized less than a century after her death. She is the patron saint of Rome, Italy and Europe.
