ancient civilisations and empires in history

let's list 'em.
off the top of my head, there's ancient greece (philosophy! sculpture! tragedy!), rome (gladiators), the byzantine empire/constantinople (mosaics, awesome architecture), ancient india (uh.. elephants?), ancient egypt (pyramids and papyrus!) .. ancient china (vases, funny hats and robes), feudal japan (ninjas)

am I missing any? add please.

Persian troops consisted mostly of light infantry, some light cavalry and some hastily trained pikemen. Nothing like his elite hoplites. At best he would just be a good general with mediocre troops and sucked into the tapestry of warlords in India. Even if he did become a figurehead and collected imperial tax from the India's states, allied with one of the warring states in China, sent a newly trained army over and carved out a bigger empire, all he would have done is be a figurehead with 100 or so legendary macedonians still alive compared to 100000 mercenaries loyal to machiavellian warlords 100s of miles away.
