Of all the monarchs to sit on the British throne in the modern era, few are as infrequently discussed as King William IV. It's a real shame, because the stories of his life are a real gas. Only the most dedicated of royal historians are probably familiar with facts about King William IV, but a close reading of his biography reveals a life filled with risk-taking, debauchery, and an anti-authoritarian streak that he carried with him right to the throne. In many ways, William IV was the original "mad lad," and modern rogues could learn a thing or two about his particular brand of misbehavior. His actions certainly make him stand out among even the most bizarre English royalty.
