Willa was the daughter of
Boso, Margrave of Tuscany and his wife
Willa of Burgundy. Boso was a grandson of
Lothair II,
King of Lotharingia via his mother,
Bertha, and his elder brother
Hugh was
King of Italy. Willa of Burgundy was the daughter of
Rudolph I of Burgundy and sister of
Rudolph II of Burgundy. Around 930 Willa married
Berengar II of Italy. The marriage was arranged by Willa's paternal uncle Hugh of Italy. About 940, however, Berengar led an unsuccessful revolt of Italian nobles against Hugh. Afterwards, he fled to the court of King
Otto I of Germany. Although she was heavily pregnant, Willa left Italy, too, travelling through the Alps in the winter to rejoin her husband in Germany. In 950 when Berengar was crowned king of Italy, Willa became his
queen consort. Berengar held Willa in high regard and designated her his
consors regni (partner in rule). The contemporary chronicler
Liutprand of Cremona, raised at the court at
Pavia, wrote about both Berengar and Willa in negative terms. He included several particularly vivid accounts of Willa's character in his
Antapodosis, including that she supposedly committed adultery with her chaplain Dominic, "a small priest, puny in height, soot-coloured, rustic, hairy, intractable, rough, shaggy, wild, uncouth, crazy; rebellious, iniquitous, with a tail-like appendage". In order to avoid discovery, Willa apparently cast spells upon her husband. When Berengar held
Adelaide of Italy captive in 951 Willa supposedly mistreated her. When Berengar was fighting against
Otto I, Holy Roman Emperor in the early 960s, Willa and her sons,
Adalbert of Italy and
Guy of Ivrea were frequently by his side. After Otto deposed Berengar, Willa and Berengar were taken as prisoners to Bavaria. After Berengar's death in 966 Willa retired to a nunnery in Bamberg, where she remained for the rest of her life. The date of her death is not known exactly. ==Marriage and issue==
