What is Chaturanga?
Origin. Most historians place Chaturanga in the Indian subcontinent during the Gupta period (c. 6th century CE).
Where it was played. It appears in Sanskrit sources and was played on the 8×8 aṣṭāpada board in royal courts, temples and learning centres, and by soldiers in army camps.
How “Shatranj” got its name. The game travelled to Sasanian Persia where it was called chatrang. After the Arab conquest it became shaṭranj. From there it spread across the Islamic world to Europe; the words “check” and “checkmate” come from Persian/Arabic shāh (king) and māt (defeated).
At a glance. The pieces represent the four arms of an Indian army—ratha (chariot), aśva (horse), gaja (elephant) and padāti (foot-soldier)—together with the rāja (king) and mantri (counsellor).

Board & initial setup
Core rules (classical Chaturanga)
- Objective: Win by capturing the opponent’s Rāja. Checks and checkmates are not used as end conditions.
- Turns: White moves first; players alternate one move at a time.
- Moves: As listed in the quick reference above.
- Pawn promotion: Upon reaching the last rank, a Padāti is promoted usually to a Mantri (Ferz). Some historical sources note file‑based promotion, but the most common reconstruction uses promotion to Mantri only.
- Special moves not present: No double pawn move, no en passant, no castling.
- Stalemate (common historical rule): If a player has no legal move, the player who delivered stalemate wins.
- Bare‑king rule (optional historical rule): If you capture all enemy pieces except the Rāja (bare king), you win—unless the opponent can also bare your king on the very next move (then it’s a draw).
- Repetition & perpetual play: Not standardized in ancient sources; use mutual agreement or tournament guidelines.
Strategy tips
- Gaja is short‑ranged (8 reachable squares total). Use it early to fork and to jump over blocks.
- Mantri is weak (1‑step diagonal). Protect it; use as support, not attacker.
- Padāti chains are slower—no 2‑step. Advance in files where you can create passed pawns.
- Since capture of the Rāja ends the game, tactical trades that expose the king are decisive.
