Adelaide of Italy
Holy Roman Empress, Catholic saint (931–999)
Feast: 16 December (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Adelaide, born in 931, daughter of King Rudolph II of Burgundy, married Lothair of Italy. After his death, probably by poison, Berengar of Ivrea tried to marry her to his son; she refused and was held almost alone in the castle of Garda, until a priest named Martin dug a tunnel by which she escaped.
She became the wife of Otto the Great and Empress, a central figure of her age. She died on 16 December 999.
The miracles
There was never a formal cause: she has been honoured as a saint since before the Church's formal processes began.
Why that counted as sanctity
An empress who kept her dignity in captivity and her faith on the throne.
