Helmichis

Helmichis was a Lombard noble who killed his king, Alboin, in 572 and unsuccessfully attempted to usurp his throne. Alboin's queen, Rosamund, supported or at least did not oppose Helmichis' plan to remove the king, and after the assassination Helmichis married her. The assassination was assisted by Peredeo, the king's chamber-guard, who in some sources becomes the material executer of the murder. Helmichis is first mentioned by the contemporary chronicler Marius of Avenches, but the most detailed account of his endeavours derives from Paul the Deacon's late 8th-century Historia Langobardorum.
