AH challenge: A world war involving every major ancient civilization/empires

Have a world war that involves every MAJOR empires that was created before the 6th century.

This means you have to have the Romans fighting with/against factions like the Persians, china, India egypt and so on.

You are free to define or add in additional rules for yourself.
 
Define major. There were a lot of civilisations before the 6th century. To get what you're after, I'm thinking it would have to involve a rather oversized Persian empire, being attacked from the outside and suffering internal rebellion at the same time.
 
Big enough to get noticed, or at the least big or powerful enough to be ranked among the top few empires in history.

Like for example, Alexander's empire, Persian empires, the Indian Maruyan(spelling?) empire, Chinese Han or Tang empire, Roman empire and so forth.
 
u need a way to prolong the war for the other empires to rise so no desicive battles i guess.
