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. And this period, you have a series of wars between the Romans and the Carthaginians, known as the Punic Wars. And we'll do videos in depth on the Punic Wars. They're called the Punic Wars because the term Punic, it comes from what the Romans called the Phoenicians.
