Sincerely whenever an history book names just <i>one</i> cause for the decline of the Roman empire, I toss it aside.<p>I get it, people want to have a nice clean explanation for the fall of the Roman empire, but mankind and societies don&#x27;t really work that way, it was a number of big and small issues that made the Roman empire come to an end and every respectable historian during - at least - the last 2 decades as stopped trying to pinpoint just one motive.
