Her husband died, apparently in the early years of her marriage, leaving her with two children, Athalaric;and Matasuentha.,;On the death of her father in 526, she succeeded him, acting as regent for her son, but being herself deeply imbued with the old Roman culture, she gave to that son's education a more refined and literary turn than suited the ideas of her Gothic subjects.
Under Athalaric he was praefectus praetorio, a post which he retained till about 540, after the triumphal entry of Belisarius into Ravenna, when he retired from public life.
Of his lost works the most important was the Historia Gothorum, written with the object of glorifying the Gothic royal house and proving that the Goths and Romans had long been connected by ties of friendship. It was published during the reign of Athalaric, and appears to have brought the history down to the death of Theodoric. His chief authority for Gothic history and legend was Ablavius (Ablabius).
In 522 the young Amalaric was proclaimed king, and four years later, on Theodoric's death, he assumed full royal power in Spain and a part of Languedoc, relinquishing Provence to his cousin Athalaric. He married Clotilda, daughter of Clovis; but his disputes with her, he being an Arian and she a Catholic, brought on him the penalty of a Frankish invasion, in which he lost his life in 531.
The ease with which so important a conquest had been effected encouraged Justinian to attack the Ostrogoths of Italy, whose kingdom, though vast in extent, for it included part of south-eastern Gaul, Raetia, Dalmatia and part of Pannonia, as Well as Italy, Sicily, Sardinia and Corsica, had been grievously weakened by the death first of the great Theodoric, and some years later of his grandson Athalaric, so that the Gothic nation was practically without a head.
Provence was added to the dominion of the new East Gothic king Athalaric, the grandson of Theodoric through his daughter Amalasuntha.
