The game of chess, or the early version of the game of chess was invented, called chaturanga. They had horsemen, which were the knights. They had infantry, which were the pawns. They had elephants, which eventually turned into bishops. But as it migrated into Persia, the Muslim world, and then into Europe, it became our modern game of chess. Famously, there's this iron pillar that is now in New Delhi that is traced back to the time of the Gupta Empire. It is believed to the reign of Chandragupta II.
