What is the main conflict in The History of the Franks by Gregory of Tours?

This work was written by a high class man during the transition from what is presently perceived to be "the ancient world" into the earliest forms of the modern world. The individual was a successful military man who later turned his talents to both religion and politics as a Bishop. The Bishop of Tours is presently deeply appreciated for writing on the history of the day, which no one else seems to have done. As a consequence, his work is part of what contemporary people have available to them to learn about the author's day and age. This work has been carefully compiled and modified by a professional editorial staff.
