Baldwin secured for his share the country of Alost and Waas, and the citadel of Ghent; and he also succeeded in obtaining in marriage for his son the Countess Richilde, heiress of Hainault and Namur. Thus was Flanders incessantly gaining new aggrandizement, while the duchy of Lorraine was crumbling away on every side.
But the lowlanders joined together under Robert, surnamed the Frison, brother of the deceased count; and they so completely defeated the French, the nobles and their unworthy associates of the high ground, that they despoiled the usurping Countess Richilde of even her hereditary possessions.
In 1071 the king of France attempted to exercise his authority over the country, by naming to the government the same Countess Richilde who had received Hainault and Namur for her dower, and who was left a widow, with sons still in their minority. The people assembled in the principal towns, and protested against this intervention of the French monarch.
