So this first map, this is roughly from the third century BCE. And third century BCE, you might remember, Rome is a republic at this time. But it's not the dominant power in the Mediterranean. Just to give ourselves some bearings, you might remember that in the late fourth century BCE, that's when Alexander conquers much of, or most of, Greece, Macedonia, the Persian Empire, which included at the time, Egypt. And as we get into the third century BCE, you still have the fragments of Alexander's Empire. That these are still significant powers in the region. You also have the Carthaginian Empire, which you see here in blue in North Africa and Southern Spain.
