And for most of this period of the Roman kingdom, so this period right over here, it's actually the Etruscans that are the dominant power. And for significant fractions of this, they were dominant over the Roman kingdom, over the city of Rome. But as we get to 509 BCE, this is when the Roman Republic is established. And in this blue-green color, this is the kingdom. The gold color, this yellow color, is the Republic. And then the red color is when the empire gets established by Julius Caesar and his adopted son, Augustus. And as we get into this, I guess you could say this Republic period, or into the Roman Republic, this is when it starts to really exert itself as more of a dominant influence in the region.
