No, actually he fled rather than fight off what was, he knew, an unwinnable war against an invading force with massive popular support in England. He was then adjudged to have forfeited his crown and spent the rest of his life in France. It may almost be a mockery of the word invasion, but there it is. It was an invasion, just a consensual one.Treblaine said:But what are the technicalities if the Parliament actually invite the new monarch in who has certain (arguable) claims to the throne?
"technically" James II was considered Abdicated when he fled to France.
And the way in which it is an invasion is that parliament could not, and cannot, appoint a king. They can ask him to stake his claim and overthrow the current king, as they did, but them simply asking him to be king does not make him king. A coup was required, so an invasion was mounted and he seized power.
