General John Churchill, 1st Duke of Marlborough, 1st Prince of Mindelheim, 1st Count of Nellenburg, Prince of the Holy Roman Empire, was an English soldier and statesman. From a gentry family, he served as a page at the court of the House of Stuart under James, Duke of York, through the 1670s and early 1680s, earning military and political advancement through his courage and diplomatic skill. He is known for never having lost a battle.

James VII and II was King of England and Ireland as James II and King of Scotland as James VII from the death of his elder brother, Charles II, on 6 February 1685. He was deposed in the Glorious Revolution of 1688. He was the last Catholic monarch of England, Scotland, and Ireland. His reign is now remembered primarily for conflicts over religious tolerance, but it also involved struggles over the principles of absolutism and the divine right of kings. His deposition ended a century of political and civil strife in England by confirming the primacy of the English Parliament over the Crown.
