History of the horse in the Indian subcontinent

It is likely enough that camel, horse and ass were in fact all a familiar feature of the Indus caravan. —Mortimer Wheeler

The horse has been present in the Indian subcontinent from at least the middle of the second millennium BC, more than two millennia after its domestication in Central Asia.
