hmmm.... well, it WAS the mughals at that time... but united?
i mean... mauryans united like a fifth of the country, the british era is too modern, but they did unite it, and the mughals got very close, but they ignored all of south india (which was united majorly by the Chholas). So there is potential for two Indian factions

!
Oh, and india was fairly important for the spices (if i remember right) cuz those were a) exotic; b) preservatives and c) yummy (lol).
and, hey, if there is any plans for making a mod with 1 or 2 indian faction(s), i would gladly contribute to animating (i'm proficient with 3ds Max, so i know what im talking about, not joking around... but i haven't yet modded a TW game ...)
