Where Mark Antony keeps control of the east, you now have Octavian with control over the west, and they gave Lepidus, who's always a bit of the third wheel here, they gave him some of the southern provinces right over there. Now it seems like all is good, but as we've already talked about, the tension between Antony and Octavian is there, it was there from the beginning. And in this video we're going to see that it gets a lot, a lot worse. So Mark Antony goes back to the east where he starts planning his invasion of Parthia. Not only does he want to take back the territory that they took in 40 BCE, but he actually wants to avenge them for Crassus' death in 53 BCE. Julius Caesar had been planning an invasion of Persia. And you have to remember, after Alexander the Great, all of these western rulers, especially the Romans, they all had their sights on Persia.
