Where is this page from?  Likely copyvio. 

It is pretty clear that this page is largely copied from somewhere else, but I can't find the source. Maybe it is a translation or copied from a book. Even the earliest version has references to arcane sources like unpublished documents from the British Foreign Office, and is well beyond the knowledge level of the editor who typed it.  WP:RS We aren't allowed to use unpublished documents as sources, nor are we allowed to extract bulk text from another source. What to do? talk
