Family and Lineage
Begga belonged to the highest rank of Austrasian nobility. Her father, Pepin of Landen, held the office of mayor of the palace, effectively governing the kingdom on behalf of the Merovingian kings; her mother was Itta (Ida) of Nivelles. Her younger sister was Saint Gertrude of Nivelles, the noted abbess.
She married Ansegisel, a son of Saint Arnulf, Bishop of Metz. From this marriage came Pepin of Herstal, regarded as the founder of the Carolingian line, and, according to some accounts, a second son named Martin (Duke Martin, or Martin of Laon).
Her descendants shaped the course of European history: she was grandmother to Charles Martel and great-grandmother to Charlemagne.
Monastic Foundation and Legacy
After her pilgrimage to Rome and profession of vows, Begga devoted herself to religious life at Andenne on the Meuse, where she was responsible for building seven churches and gathering a monastic community. She governed this community as its first abbess until her death.
She is honored as the patroness of Andenne. Her cult predates the formal papal canonization process, having been recognized through the pre-Congregation tradition of the early Church.
The Beguine Tradition
Some later theories attributed the origin of the medieval Beguine movement to Begga. Modern scholarship, however, increasingly favors the alternative explanation that the Beguines took their name from the priest Lambert le Bègue, under whose protection their ministry flourished, rather than from Begga herself.
