Data is compiled from the book “All the Countries We’ve Ever Invaded: And the Few We Never Got Round To.” by Stuart Laycock. At various times in history, the British (United Kingdom) have invaded or fought conflicts in almost 90 percent of what are now the modern day countries around the globe. Mr. Laycock’s analysis of the histories of the almost 200 countries in the world found only 22 which have never experienced an invasion by the British, of which only a comparatively small proportion of invaded states actually formed an official part of the empire. The remainder have been included because the British were found to have achieved some sort of military presence in the territory – however transitory – either through force, the threat of force, negotiation or payment. Incursions by British pirates, privateers or armed explorers have also been included, provided they were operating with the approval of their government.
