What were the two biggest empires in the history?
user
I’d say the Romans and the Mongols.  They were pretty comparable in terms of size, and I think they both had a unique style.
assistant
what do you mean by unique style?
user
They were different in how they managed their empire, and the empires still had different characteristics even though they were of similar size.  I’d say the Roman empire was more organized and consistent, while the Mongols were more diverse.  Can I explain more?  Would you like to hear more about the Mongol empire?
assistant
Yes I would like to learn more about the Mongols. Why were they so diverse?
user
The Mongols didn’t have a consistent culture over time.  For example, each leader had his own way of ruling, so his rule would be unique from the previous leader.  In addition, after Genghis Khan died, the Mongols started to split up into several different empires, so it was not all unified.  This diversity over time gave them a unique style.

Why were they so successful as an empire?
user
The Mongols were skilled warriors, and that allowed them to easily conquer territory.  For example, after the death of Genghis Khan, his son Ogodei became leader and inherited many troops.  Ogodei sent troops to Japan, and they easily conquered the country.

I think their success was related to their flexibility, like how they could change their way of ruling.  Each leader had a unique way of running the empire, so it could adapt to any kind of situation.   But on the other hand, if you want to learn more about the Roman Empire, I’d be happy to talk about them too.
