@Grainiac well basically ...
Chess's is likely to have originated in India from chaturaṅga which translates as "four divisions" (of the military). Infantry, cavalry, elephantry, and chariotry. These forms are represented by what we now know as the pawn, knight, bishop, and rook respectively.
The rules of the game would be further developed in Sassanid Persia around 600 AD. Players would shout "Shāh!" (Persian for "King!") when attacking the opponent's king, and "Shāh Māt!" (Persian for "the king is helpless" – see checkmate) when the king was attacked and could not escape from attack. Here in Persian the name of the game was changed to chatrang and then shatranj.
Chess spread directly from the Middle East to Russia, where chess became known as шахматы (shakhmaty, literally "checkmates", a plurale tantum).
The game was developed extensively in Europe. By the late 15th century, it had survived a series of prohibitions and Christian Church sanctions to almost take the shape of the modern game. Modern history saw reliable reference works, competitive chess tournaments, and exciting new variants. These factors added to the game's popularity, further bolstered by reliable timing mechanisms (first introduced in 1861), effective rules, and charismatic players.
