Haha - have you heard of the Chola empire - an empire that covered the whole of South India, Indonesia nad malaysia. Have you heard of the viyaynagara empire?
haha north india is cold - haha :-) You sure its not from being raped by Northern invaders for 1000 years. :-) Why talk about alexander - talk about the rape of your woman and daughters that occured 1000 years ago until the british came :-)
Next you going to tell me - nobody invaded South India becaiuse its hot here :-)
There is a reason the british called north indian cowards - nad there is a reason the british made sure no weapon was given to a south indian :-) Remember how long it took to invade south india and then how quick the bristish took to invade the rest of India :-)
