William IV

William IV was King of the United Kingdom of Great Britain and Ireland and of Hanover from 1830 until his death in 1837.

Background
William IV only inherited the throne at the age of 64 and was only king for 7 years. In those years, he restricted child labor and abolished slavery in almost the whole British Empire. He left no legitimate children at the time of his death, so the throne was passed to his niece Victoria.

Appearances
William IV is mentioned-only in Fallout 3 in the National Archives' pop quiz terminals as one of the possible answers.
