[2][3] The abbey was founded by Itta of Metz, the widow of Pepin of Landen, Mayor of the Palace of the Kingdom of Austrasia, with their daughter, Gertrude of Nivelles.
During this period, trials for the family are mentioned involving the usurper Otto's bid to replace the Pippinids at the side of the king.
According to Wemple, "during the second half of the 7th century, women in Neustrian-Burgundian families concentrated on the creation of a network of monasteries rather than on the conclusion of politically advantageous unions, while families whose holdings were in the northeastern parts of the kingdom, centering around the city of Metz, were more concerned with the acquisition of power through carefully arranged marriages."
At this time, Gertrude took the "whole burden of governing upon herself alone," placing affairs of the family in the hand of "good and faithful administrators from the brothers."
The abbey had close ties to the royal family, and played an important role in the social life of the palace.
From the 12th century, the character of the community began to change to a more prestigious one, so that the members became canonesses regular who came from among the nobility, as attested in a document dated 1462.
