Clotsinda was a 7th-century saint and the abbess of Marchiennes Abbey in Flanders. Born into a noble Gascon family, she married Saint Adalbard, a nobleman in the court of the Frankish kings. Following the assassination of her husband, she dedicated herself to religious life, eventually governing the monastery at Marchiennes for four decades. Her life and her family's religious devotion are documented in the Vita Sanctae Rictrudis, a hagiography written by the monk Hucbald in the 10th century.
Life and devotion

After the death of her husband, Clotsinda faced significant pressure from the king to remarry. She resisted these royal demands to maintain her religious vows, a decision supported by her spiritual advisor, Saint Amandus. Her family's commitment to the church was notable, as her four children were also recognized as saints. She spent forty years leading the monastery at Marchiennes, where she died at approximately 74 years of age.
Veneration
Clotsinda is honored within the Catholic tradition. Her life is associated with various miracles, such as the healing of physical ailments, which are recorded in her hagiography. She is commemorated with a feast day on May 12, and her remains are entombed at Marchiennes. Her legacy continues through the various churches in Flanders dedicated to her memory.
