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. They said, hey, maybe I can be just like Alexander the Great and take over the Persians. So Mark Antony is planning his invasion of Persia, but he doesn't get the troops that he wants from Octavian. And so that starts to build the tensions even further, but he goes to his lover, Cleopatra, who is the richest woman in the world, the pharaoh of Egypt, and says, hey, can you give me some Egyptian troops?
