Rome Wasn't The Only One That Fell

However, for every influential superpower that we remember, countless others go forgotten, despite rising to incredible heights, reminding us of the complex, cyclical nature of power. Here are 20 great empires that have faded into the mists of time.

Seen as the last great pre-Islamic Persian empire, the Sasanians were a main rival to the Roman Empire for centuries.
