9 September – On this day

William II (c. 1056 – 2 August 1100), the third son of William I of England, was King of England from 1087 until 1100. He initially did not hold Normandy as this was passed to his elder brother Robert, but William eventually wrested control nominal control from him in 1091. William earned the nickname Rufus either because of his red hair or his propensity for anger.

William was a capable soldier, but subject to fits of temper, he did not marry, nor did he produce any offspring, legitimate or otherwise. He died after being struck by an arrow while hunting, under circumstances that remain murky. Circumstantial evidence in the behaviour of those around him raise strong but unproven suspicions of murder. His younger brother Henry hurriedly succeeded him as king.
