Chaturanga (Sanskrit: चतुरङ्ग) is the 6th-century Indian strategy board game from the Gupta Empire — the earliest known ancestor of modern chess. It was played on an 8×8 board called the Ashtapada with six types of pieces representing the four divisions of the ancient Indian army: infantry (Padati), cavalry (Ashva), war elephants (Gaja), and chariots (Ratha), led by the Raja (king) and Mantri (minister). Chaturanga is the direct ancestor of Shatranj, which in turn became modern chess.

What does Chaturanga mean?

Chaturanga is Sanskrit for 'four-limbed' or 'four divisions.' It comes from catur (चतुर, meaning 'four') and aṅga (अङ्ग, meaning 'limb' or 'body part'). The name refers to the four branches of the ancient Indian military: infantry, cavalry, elephants, and chariots — all represented as pieces on the board.

When was Chaturanga invented?

Chaturanga is believed to have originated in the Gupta Empire of India around 550–600 CE. The earliest written reference to the game is in the Harshacharita (620 CE), a Sanskrit biographical poem by the court poet Bāṇabhaṭṭa. Archaeological evidence and textual analysis suggest the game existed at least decades before this first written mention.

How is Chaturanga different from chess?

Chaturanga has several key differences from modern chess: (1) The Bare Raja rule — reducing the opponent to a lone king while retaining at least two pieces is an immediate win, taking priority over checkmate; (2) Stalemate is a loss for the stalemated player, not a draw; (3) The Gaja (elephant) leaps exactly two squares diagonally and cannot be blocked; (4) The Mantri (minister) moves only one square diagonally — far weaker than the modern Queen; (5) No castling, no en passant, no double pawn push; (6) Pawns promote only to Mantri.

Is Chaturanga the origin of chess?

Yes. Chaturanga is the direct ancestor of all chess variants. The chain is: Chaturanga (6th c. India) → Shatranj (7th c. Persia/Arabia) → modern chess (15th c. Europe). It is also the ancestor of Shogi (Japanese chess) and Xiangqi (Chinese chess) through other branches of the same game family.

What board is Chaturanga played on?

Chaturanga is played on the Ashtapada — an 8×8 board whose name means 'eight steps' in Sanskrit. The Ashtapada predates Chaturanga; it was originally used for a racing game played with dice. Unlike the modern chessboard, the original Ashtapada had no alternating colors — the black and white squares are a later European innovation.

Did Chaturanga have dice?

The two-player Chaturanga described in most historical sources is a pure skill game with no dice. However, a four-player variant called Chaturaji did use dice to determine which piece a player could move each turn. Chaturanga.online implements the two-player skill game — the direct ancestor of Shatranj and modern chess.
