But Mark Antony, who was in control of the east of the empire, he wasn't able to deal with it immediately because he goes to Brundisium in order to take his wife's side on a civil war between her and Octavian. Now his wife dies and he makes good with Octavian, in fact, so good with Octavian, he marries Octavian's sister, Octavia, and they decide, alright, let's continue to be friends here. And they divide the Roman Empire, the Roman Republic, whatever you want to call it, between them. 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.
