20. One of Ancient History’s Greatest What Ifs: What If Julius Caesar Had Invaded Parthia?
Julius Caesar was assassinated on the Ides of March in 44 BC, just days before he was scheduled to leave Rome and head to the east, to lead an invasion of Parthia. It was to be a massive endeavor with the largest force he had ever led: 16 legions and 10,000 cavalry, in addition to support troops. As a preliminary, Caesar planned to first invade and conquer the kingdom of Dacia, roughly modern Romania, which he calculated could be accomplished by the end of 44 BC.

The following spring, he would move on to Parthia. However, Parthia was no pushover, as evinced by the Battle of Carrhae in 53 BC, where a Parthian cavalry force of 10,000 had all but annihilated a much larger Roman army of roughly 50,000, led by Caesar’s colleague, Crassus. So it was not a foregone conclusion that Caesar could have conquered Parthia.
