The tomb, which can be found in the church in St Germain en Laye, is the last resting place of King James II, the last British king to be removed from the throne.
The younger brother of Charles II, he ascended to the throne in 1685. He was extremely unpopular for the following five reasons
1- He was a catholic
2- He was a catholic
3- He was a catholic
4- He was a catholic and
5- He tried to rule as an autocrat (not learning the lesson meted out to his father by Oliver Cromwell ---- His father was beheaded).
He was deposed in 1688 during the Glorious Revolution (Called glorious perhaps because it was pretty well nigh the only revolution ever to be bloodless or at least not very bloody!.. That's not entirely true but show me a bloodless revolution anywhere)
He attempted to wrest back the throne from his successor. In 1690 he sailed to Ireland. He was defeated at the battle of the Boyne in 1690 and then, more comprehensively, at the less well-known battle of Aughrim in 1691. James subsequently escaped from Ireland leaving his supporters there to their fate. He was there after known in Ireland as Séamus an Chaca, James the Shithead (A title well deserved by the worst example of the useless shower that made up the Stuart monarchs)
James II ended up in France, living at the chateau of St Germain en Laye. He died in 1701
So what has this got to do with Orange? Well his successor to the Throne of England was ...
WILLIAM OF ORANGE!
