Rosamund was born into a kingdom in crisis, as the Gepid people had been fighting a losing battle against the
Lombards since 546, firstly within the context of a Lombardic–East Roman alliance, and later against the Lombards and the
Avar nomads. These wars had taken the lives of not only her grandfather king
Thurisind, but also her uncle,
Thurismund, both of which served to establish a long-standing hatred of the Lombards in her father, Cunimund, which he passed down to her. This hatred was what spawned the final war of the Gepids, as Cunimund attempted to win back lost lands against the Lombards. The war, however, quickly turned, and in 567, the
Gepid Kingdom would be completely subdued by a mixture of Lombard and Avar forces, her father was decapitated and she, along with many other Gepids, was taken as a prisoner of the Lombards (see
Lombard–Gepid War (567)). However, in an attempt to secure a male heir and following the death of his first wife
Chlothsind, Alboin took her as his wife. Alboin was noted for his cruelty towards her; his most famous act of cruelty was reported by
Paulus Diaconus, who states that at a royal banquet in Verona, Alboin forced her to drink from the skull of her dead father (which he carried around his belt), inviting her "to drink merrily with her father". After this, she began plotting to have her husband assassinated. Thus, Rosamund met with the king's arms bearer and her lover,
Helmichis, who suggested using Peredeo, "a very strong man", Immediately afterwards, Helmichis planned to marry Rosamund and usurp the throne by claiming kingship. However, this plan gained little support from the various duchies of the Lombard kingdom, so Rosamund, Helmichis, and
Albsuinda, Alboin's daughter by his first wife, fled together to the East Roman stronghold of
Ravenna with a large proportion of Alboin's private treasures. Rosamund and Helmichis married in Ravenna, but were soon divided when Rosamund, in an attempt to curry favour, took as a lover Longinus, the
exarch, who had helped them plan the murder of Alboin. At the urging of Longinus, who promised to marry her, she attempted to murder her former lover Helmichis by poisoning, handing him the drink after he had washed; however, she was instead murdered by Helmichis, who forced her to drink the poison before committing suicide by the same means. ==Rosamund in later culture==
