So those with even a basic familiarity with Ancient Phoenecian History will have heard of this Italian city -- about 23 centuries ago, they managed to unite most of the peninsula, and subsequently even managed to defeat Carthage in a massive war (or fight them to a draw, depending on who you ask), and spread their power over several islands in Oursea [the Mediterranean].
Of course, Hannibal the Great put a stop to that, but the capability and sheer persistence of the Latins made them a very worthy adversary of even one of the greatest military commanders of the era. So much so that, as members of this board well know, people have imagined for centuries how Rome might have won the war.
So let's say they do -- just how powerful might this "Roman a Empire", if you will, have gotten? And how would history be changed?
