William II Rufus (c. 1056 – 2 August 1100) was the third son of William the conqueror. William II’s coronation was conducted on Sunday, 26 September 1087, 17 days after inheriting the crown.
Following the custom set by his father, William was crowned in Westminster Abbey. Unfortunately there is no record of who attended although the Anglo-Saxon Chronicle records that Lanfranc, Archbishop of Canterbury performed the ceremony. The coronation was according to the Anglo-Saxon Christian tradition.
