Godfrey of Brabant (died July 11, 1302, in Kortrijk), was Lord of Aarschot, between 1284 and his death in 1302, and Lord of Vierzon, between 1277 and 1302.
On October 29, 1284, his father made him Lord of Aarschot. This reestablished a dynasty that had been broken in 1172 when Godfried III, Count of Aarschot, sold his county and, as a result, his heritage, to Godfrey's great-grandfather Godfrey III, Count of Louvain. The transaction was for an unknown amount of money and an equally unknown reason. Godfrey of Brabant donated the land for new city fortifications to the inhabitants of Aarschot.[3]
In 1292, he negotiated a peace between France and the Count of Flanders. After the death of his brother, he supported his nephew John II of Brabant against all internal and external opposition.
In 1302, when Flanders revolted against King Philip IV of France, Godfrey and his only son joined the army of his French ally in the Battle of the Golden Spurs. Both were killed, as were many more knights of Brabant. His estates were divided among his four married daughters.
He married in 1277 Jeanne Isabeau dame de Vierzon (died 1296), daughter of Hervé IV, Lord of Vierzon, and Jeanne de Brenne. They had 1 son and 6 daughters :
