[Generally, in order to promote one’s political career, one wants to become famous before dying in battle, as Crassus did at Carrhae. ]
Consul was as high as you could get in the Roman republic, so there’s that. Given that they were elected once a year, consuls were a dime a dozen. Without Carrhae, Crassus would have been a footnote - a consul, but not a noteworthy figure, who put down one of a number of slave rebellions. But Carrhae made him immortal, even as it took both his and his son’s lives, along with most of the army* they led. Life can be funny in that way. If Varus hadn’t gotten his legions annihilated by Hermann, how well-known would he be?
* What’s curious is how his survival, or success, would have affected Caesar’s fate. Would the power struggle that followed Crassus’s death have broken out at all?
Well, if you want Bloomies to go straight to Carrhae, that’s fine with me, but I was pointing out that Crassus had to buy his way into fame well before that.
