1090 (during)
Relations between Henry’s brothers, Robert and William, continued to be strained.
1090 (late)

Henry and his brother William II were reconciled and joined forces to campaign in the Norman Vexin.
1100 (2nd August)
Henry’s brother, King William II was killed by an arrow while hunting in the New Forest.

This put Henry in an awkward position since the bishops and abbots he had appointed were great landowners and he needed their support. Henry avoided the issue.
1100 (11th November)
Henry married Edith, daughter of Malcolm Canmore, King of Scotland at Westminster Abbey. Edith’s mother, Margaret was the sister of Edgar Atheling, the last royal Saxon descendant. The marriage therefore represented the union of Norman and Saxon royal lines as well as cementing agreement with Scotland.

1105 (during)
Henry sent his trusted friend Robert Fitzhamon into Normandy. After provoking a fight with Robert Curthose, Fitzhamon was captured. Henry invaded Normandy in protest at Fitzhamon’s imprisonment in Bayeux and placed Bayeux under siege. When the town refused to surrender Henry burnt it.

1107 (during)

1110 (during)
The royal caravan still toured the country as it had in Saxon times, collecting taxes and settling problems in the royal court, but it was becoming increasingly necessary to establish a central court and financial clearing house. Roger, bishop of Salisbury, Henry’s closest advisor, was given the title of Justicar, (judge). Henry also set up a financial-counting system using a large chequered cloth. The royal treasurer and officials argued general policy and specific expenditure plans across this cloth. This department became known as the ‘exchequer’.

1118 (throughout)
Henry spent the whole year in Normandy defending it against attack from the King of France, the Count of Anjou and the Count of Flanders. With Henry’s long absences in Normandy it was necessary to leave the government of England in the hands of a vice-regal committee.

1121 (during)
The death of William Aetheling led to the disintegration of the peace treaty made with Fulk of Anjou in May 1119.
1121 (January)

1135 (late November)
King Henry I became ill after eating lampreys against his doctor’s advice. It soon became evident that Henry I was dying. His daughter and son-in-law were in Anjou and some days away from England. Henry’s nephew, Stephen, on the other hand, was in Boulogne, a mere days travel from England.
