Edgar's new brother-in-law supported Edgar's claim to the throne of England. Edgar's and Malcolm's plans caused the north of England—what is now Yorkshire, Durham, Northumberland, Lancashire—to start a series of local rebellions against Norman rule. This led to the Harrying of the North, William the Conqueror's campaign to subdue the northern territories and stop Edgar's plans. The Harrying was vicious, using scorched earth tactics to starve out the rebels and replacing all English aristocracy with Normans.
Edgar had returned to England to become the focal point for the rebellions, but retreated to Scotland when things got bad. Later that year, King Sweyn of Denmark arrived in the north, triggering a fresh set of uprisings. Edgar, the Northumbrians, and the Danes combined to take York from Norman control. William arrived later, bought off the Danes (they were still susceptible to Danegeld), and caused Edgar and his other followers to, once again, retreat to Scotland.
In 1072, William invaded Scotland, forcing Malcolm to recognize William's overlordship. Part of the agreement was the expulsion of Edgar, who went to Flanders where Robert the Frisian was hostile to Normandy. Edgar returned to Scotland in 1074, but then received an offer from Philip I, King of France. Philip offered him a castle near the Norman border from which he could hassle Normandy. Embarking for France, a storm wrecked his fleet along the English coast, whereupon Normans hunted him down. He fled back to Scotland on foot, after which Malcolm convinced him to give up his dreams of a throne and submit to William.
Edgar tried that route, but felt he deserved better treatment because of his status. The Domesday Book in 1086 lists two estates in Hertfordshire belonging to Edgar, although by that time he was no longer living in England. Dissatisfied, he had gone to Italy to settle in Apulia, which was occupied by Normans. A few years later, however, he returned to England.
After William's death in 1087, Edgar's fortunes seemed to rise a little with William's sons, who clearly had no concerns that this older man was going to try to take their throne. Instead, they involved him in their reigns.
For the happy remainder of Edgar's complicated life, tune in tomorrow.
