Chilperic I
(chl´prk) (KEY) , d. 584, Frankish king of Neustria (56184), son of Clotaire I. He feuded bitterly with his brother Sigebert I, who had inherited the E Frankish kingdom that came to be known as Austrasia. Their struggle became savage after Chilperic and his mistress and future wife, Fredegunde, murdered (567) Chilperics second wife, Galswintha; she was the sister of Sigeberts wife, Brunhilda. In the wars between the two brothers, Sigebert overran Neustria before his death (575). Later, Chilperic was murdered, probably at the instigation of Brunhilda. The feud was inherited by Chilperics son and successor, Clotaire II.
