Arnout III, Count of Aarschot
Arnout III, Count of Aarschot, son of Arnout II, Count of Aarschot, and his wife whose name remains unknown. Arnout is sometimes confused with his father, especially in regard to the blood shedding at Aachen in 1115.
Arnout supported the founding of the Averbode Abbey in 1134, part of the Archdiocese of Mechelen-Brussels, that was made possible by donations by Arnold II, Count of Looz, the Abbey of Sint-Truiden, the lords of Aarschot and Diest, and Godfrey III, Count of Louvain. In at least two documents, Arnout was not referred to as a count.
Arnout married Beatrix of Looz, daughter of Arnold I, Count of Looz and sister of his fellow benefactor of the Averbode Abbey. Arnout and Beatrix had four children:
Upon his death, Arnout was succeeded as Count of Aarschot by his son and namesake.
