[1] She acted as Regent during the minority of her stepson Rodoald after the death of her second husband in 652.
[3][1] As her mother was the daughter of duke Garibald I of Bavaria, Gundeberga is considered part of the Bavarian Dynasty of Lombard royalty.
After the death of her husband in 636, she married his successor Rothari, (king of the Lombards; 636-652).
Since Rodoald was too young to rule in accordance with Lombard custom, Gundeberga formally acted as his regent.
We do not know the exact year of her death, but only that she was buried in Pavia in the church of San Giovanni Domnarum, which she founded.
