You don't say which William you mean. Assuming you mean William the Conqueror (of England) the answer is as follows.
· Welsh border in 1067.
· Exeter Rebellion, 1068.
· 1068: Edwin and Morcar attempted rebellion in mercia
· In 1068, Gospatric and Edgar the Aetheling led a serious rising in the north
· Gospatric fled to Scotland. His replacement, the Norman Robert Cumin, was attacked and killed - trapped in a burning house - by rebel forces in January 1069.
· This revolt spread to York, where the Norman garrison once again came under attack. William marched to York to relieve it.
· Summer 1069: Danish army of 240 ships landed in England, pressing the claim of King Swein of Denmark - a relative of Cnut - to the English crown. The Vikings joined forces with Gospatric and the English rebels, who marched on York, besieged and captured it.
· There was a good deal of support for the rebels amongst the Anglo-Scandinavians of the north, and the example of the leaders in York inspired the revolts across the country, particularly in Northumbria.
The Harrying of the North
· William began by encircling the Viking encampment to [revent them from joining up with southern rebel forces.
· Over the winter of 1069-70, William took forces north and burnt the land, destroyed the cities including York, and slaughtered the inhabitants.
East Anglia / The Isle of Ely
· Summer of 1070, King Swegn of Denmark himself arrived in East Anglia to join his Viking army which had not left England in the spring as promised,
· The Danes occupied the Isle of Ely, where Hereward the Wake joined them, Morcar and possibly Edwin.
· Together they looted Peterborough Abbey.
Scotland
· Malcolm had already ransacked Durham and Cleveland.
· In the summer of 1072, William responded, marching into Scotland with an army and co-ordinated the English fleet that sailed up the Tay.
The Revolt of the Earls
· 1075, the last major revolt against William's reign.
