== Roman Empire vs. Republic == 

 :It is often considered a period of transition, sometimes even of decline or decadence, between the brilliance of the Greek Classical Era and the emergence of the Roman Empire." 

 Is "Roman Empire" accurate in this context, after all it was the Roman Republic'' that conquered Greece, the Empire was born more than a century later? If there will be no objections, I'll change it to just "Rome", or something.
