The bloody nature of the times is depicted naïvely by Gregory, Bishop of Tours, who wrote the history of the Franks. See, e.g., the stories of Ingeltrudis, Rigunthis, Waddo, Amalo, etc., in Book 9. Gregory was born in 539.

CHAPTER V
DIGRESSION OF THE LATER HISTORY OF ROMAN LAW
With Charlemagne, who was crowned Emperor by the Pope in the year 800, began the definite union of Church and State and the Church's temporal power. Henceforth for seven centuries, until the Reformation, we shall have to reckon with canon law as a supreme force in determining the question of the position of women. A brief survey of the later history of the old Roman Law will not be out of place in order to note what influence, if any, it continued to exert down the ages.
