But these ties were soon dissolved after the accession of Lewis, who found his interests to be, in so many particulars opposite to those of the English monarch, and who became sensible of the danger attending the annexation of Normandy to England.

He joined, therefore, the counts of Anjou and Flanders in giving disquiet to Henry's government; and this monarch, in order to defend his foreign dominions, found himself obliged to go over to Normandy, where he resided two years.

The war which ensued among those princes was attended with no memorable event, and produced only slight skirmishes on the frontiers, agreeably to the weak condition of the sovereigns in that age, whenever their subjects were not roused by some great and urgent occasion.

Henry, by contracting his eldest son, William, to the daughter of Fulk, detached that prince from the alliance, and obliged the others to come to an accommodation with him.
This peace was not of long duration.

His nephew William retired to the court of Baldwin, earl of Flanders, who espoused his cause; and the king of France, having soon after, for other reasons, joined the party, a new war was kindled in Normandy, which produced no event more memorable than had attended the former.
