Deletion of List of longest-lasting empires (2nd nomination)

Comment: per Ogre's comments.  Keep this one and we'll be seeing RFCs and edit wars over who's countries historical empire was better etc...  Even when sources meet  they rarely agree with one another

Comment: There's no IF about it.  There are multiple books which cover historical empires as a general topic - see http://books.google.co.uk/books?id=zQWl1eG9DEoC Empires: the logic of world domination from ancient Rome to the United States or http://books.google.co.uk/books?id=dAz-rphWxMYC Empires, for example.  All we have to do is summarise and cite the work of these various scholars and we're good.  Issues of definition and measurement are unimportant because all topics have difficulties of this kind - see List of rivers by length, for example.  As usual, it's just a matter of doing some sourcing and then discussing the results.  Deletion is quite unhelpful in this and there seems to have been no attempt to engage with the topic per |our deletion policy
