Amalafrida

Amalafrida was the daughter of Theodemir, king of the Ostrogoths, and his wife Erelieva. She was the sister of Theodoric the Great, and mother of Theodahad, both of whom also were kings of the Ostrogoths.
In 500, to further cement his authority over the Vandals, Theodoric arranged a marriage alliance with Thrasamund, king of the Vandals, who became Amalfrida's second husband. She brought a very large dowry, but also 5,000 Gothic troops.
After her husband Thrasamund's death, his successor Hilderic issued orders for the return of all the Catholic bishops from exile, and Boniface, a strenuous asserter of orthodoxy, bishop of the African Church. In response, Amalfrida headed a party of revolt; she called in the assistance of the Moors, and battle was joined at Capsa, about three hundred miles to the south of the capital, on the edge of the Libyan desert.
In 523, Amalafrida's party was beaten, and Hilderic had her arrested and imprisoned in a successful bid to overthrow Ostrogothic hegemony; he also had her Gothic troops killed. She died in prison, exact date unknown.
Amalafrida had two children, the aforementioned Theodahad and Amalaberga, who married Hermanfrid, king of the Thuringii. It is not known who the father of these children was.
