Well maybe you are right - linguistically civilization implies cities, which the hunter gatherers dont have. Central government I dont know, I think Greece got by a long time on loosely confederated city states. According to archeologists like Brian Fagan, whom I quote: "The generally agreed upon, special attributes that separate civilizations from other societies can be listed as follows: * Urbanized societies, based on cities, with large, very complex social organizations... *Symbiotic economies based on the centralized accumulation of capital and social status through tribute and taxation... *Advances toward record-keeping, science and mathematics, and some form of written script. *Impressive public buildings and monumental architecture." So you are right, none of my aforementioned examples quite fit. Well, based on that, and keeping in mind continuity of rule, I guess I would have to give the nod to... England?
