Chlothar II in the context of "Dismemberment"

Under the Merovingian dynasty, the mayor of the palace or majordomo,(Latin: maior palatii or maior domus) was the manager of the household of the Frankish king. He was the head of the Merovingian administrative ladder and orchestrated the operation of the entire court. He was appointed by the king from among the magnates, the most powerful families. Austrasia, Neustria and Burgundy had their own mayor of the palace. After Chlothar II, who ruled over the entire Frankish Kingdom, had ordered the execution of Warnachar, the mayor of Burgundy, the magnates of Burgundy declared in 626 not to want their own mayor anymore. This declaration marks the effective end of the Burgundian court and the beginning of the Neustrian-Burgundian political alliance against Austrasian influence. The Austrasian magnates revolted and the Battle of Tertry of 687 became the Austrasian victory with Pepin of Herstal as their leader and the new mayor of the palace.

During the second half of the seventh century, the office evolved into the "power behind the throne". At that time the mayor of the palace held and wielded the real and effective power to make decisions affecting the kingdom, while the kings were increasingly reduced to performing merely ceremonial functions, which made them little more than figureheads (rois fainéants, 'do-nothing kings'). The office may be compared to that of the peshwa, shōgun, sarvadhikari, or prime minister, all of which have similarly been the real powers behind some ceremonial monarchs.

Theudebert II (French: Thibert or Théodebert) (c.585–612), King of Austrasia (595–612 AD), was the son and heir of Childebert II. He received the kingdom of Austrasia plus the cities (civitates) of Poitiers, Tours, Le Puy-en-Velay, Bordeaux, and Châteaudun, as well as the Champagne, the Auvergne, and Transjurane Alemannia.

During his early years, his grandmother Brunhilda ruled for Theudebert and his brother Theuderic II, who had received the realm of Burgundy. After the two brothers reached adulthood, they were often at war, with Brunhilda siding with Theuderic. In 599, he expelled his grandmother from his court, possibly at the instigation of the nobility, who had grown tired of Brunhilda’s influence on the King. She then went to his younger brother who readily accepted their grandmother at his court. She instigated a short but vengeful war between the brothers in the same year and Theuderic defeated Theudebert in a pinched battle at Sens, but when their cousin Chlothar II saw an opportunity to expand his realm, he invaded Neustria. Under their grandmother, the two brothers made a temporary truce and allied against their cousin, defeating him in a battle at Dormelles (near Montereau), thereby laying their hands on a great portion of Cholthar’s part of Neustria (600–604). At this point, however, the two brothers took up arms against each other for the second time; Theuderic defeated Theudebert at Étampes. In 605, Theudebert refused to aid his brother whose kingdom was invaded by Clothar II. In 610, Theudebert extorted Alsace from his brother and Theuderic took up arms against him, yet again for a third time.
