I keep reading this online and I find it to be nonsense. Over a thousand years earlier the Romans developed all the conquered lands. They built massive infrastructure projects: roads, ports, aqueducts, buildings. And brought sanitation and education. Ghengis Khan only brought peace and trade networks, something Rome also brought with them.

Next up, how Carthaginians were actually the good guys and child sacrifice was not that bad.

He didn't say Genghis Khan and the Mongols did everything the Ancient Romans did.

He said both had their rise to power rooted in a (for-the-time) unique meritocratic element, where people would join you compared to the alternative options due to the ability to advance.
