Chlothar I
Sigebert's father, Chlothar I, had reunited the four kingdoms of the Franks, but when he died, Sigebert and his three brothers divided them again. According to historian and bishop Gregory of Tours, Sigebert's marriage to a Visigothic princess was a criticism of his brothers' choices in wives. Instead of marrying a low-born woman, Sigebert chose a princess of education and morals.
