Several

After a millennium passed in the Buddhist era, various references occur to a game that seems the direct forbear of present-day chess. According to Sanskrit literature, apart from the central king and counselor, the pieces represented the quadrants of the ancient Indian army: war chariots, cavalry, elephants, and foot soldiers. The Upper Basin of the Ganges, or thereabouts, was the locale where this game first appeared. Since the area was a Buddhist stronghold, it is not unreasonable to assume that their monks had a hand in its inception. Since Buddhists oppose the killing of any form of life, it can be hypothesized that the game was invented as a bloodless substitute for war (by allowing men to engage in a combat of a higher sort).
