Anglo-Norman War, 1101
(July 1101)

After the death of William Rufus, his younger brother, Henry Beauclerc immediately usurped the throne and was recognized by France's King Philip. Robert Curthose, Duke of Normandy, had expected to succeed, but was on crusade and did not return until a month after Rufus' death. Curthose reasserted his control over Normandy, and launched an attack on England, advancing inland to Alton. There he and Henry came to an agreement by which they accepted the status quo of the territorial division, Henry was freed from his homage to Robert, and agreed to pay the Duke an annual sum (which, however, he only did until 1103).
