About Chaturanga

The four divisions

Chaturanga means 'four divisions' — infantry, cavalry, elephants and chariots — the branches of the Indian army that became the pawn, knight, bishop and rook. The Raja moves like a king, the Mantri (minister) one square diagonally, and the Gaja (elephant) most likely leaps two squares diagonally, though scholars still debate it.

No single rulebook survives; the app uses the most widely accepted reconstruction. Pawns move one square and promote to a Mantri; there is no castling, no en passant and no double step.

Legacy

From Chaturanga the game travelled west to Persia as Shatranj and on to Europe as modern chess, and east as Xiangqi, Janggi, Makruk, Sittuyin and Shogi. Playing it shows how much of the modern game — the knight's move, the rook's power, the weak early queen — was there from the beginning.
