Anstrudis was a 7th-century abbess who led the Abbey of St. John in Laon. Born around 645 to Saint Blandinus and Saint Salaberga, she entered the monastery at age twelve to avoid marriage. Following the death of her mother in 670, she assumed leadership of the community. Her tenure was marked by political instability in the Frankish kingdoms, including a conflict with the Neustrian faction that resulted in the murder of her brother, Baldwin. She is remembered as a devout monastic leader and a saint.
