When did King William IV reign?

Answer King William II of England was born about 1056, became King on 9th September 1087 and reigned until his death on 2nd August 1100. Controversy surrounds his death in a "hunting accident" because the man who accidentally shot him with an arrow was, in fact, an Excellent bowman. King William's brother Henry, who became King after William died was also in the hunting party.
