AMALASUNTHA or AMALASUENTHA, queen of the Ostrogoths (d. 535), daughter of Theodoric, king of the Ostro goths, was married in 515 to Eutharic, an Ostrogoth of the old Amal line, who had previously been living in Spain. 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 at Ravenna, 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 liter ary turn than suited the ideas of her Gothic subjects. Conscious of her unpopularity she banished, and afterwards put to death, three Gothic nobles whom he suspected of intriguing against her rule, and at the same time opened negotiations with the emperor Justinian with the view of removing herself and the Gothic treas ure to Constantinople. Her son's death in 534 made but little change in the situation. Amalasuntha, now queen, invited her cousin Theodahad to share her throne. Theodahad, notwithstand ing a varnish of literary culture, was a coward and a scoundrel. He fostered the disaffection of the Goths and, either by his orders or with his permission, Amalasuntha was imprisoned on an island in the Tuscan lake of Bolsena, where in the spring of 535 she was murdered in her bath.
The letters of Cassiodorus, chief minister and literary adviser of Amalasuntha, and the histories of Procopius and Jordanes give us our chief information as to the character of Amalasuntha.
