Chaturanga is an ancient Indian game which is presumed to be the common ancestor of chess, shogi, and makruk, and related to xiangqi and janggi. (See Origins of chess for more information on the ancestry of chess.) Chaturanga has been played since the 6th century or earlier, hence Chaturanga is most commonly believed to be the oldest version of chess. Chaturanga is the direct ancestor of Shatranj, which was the form that brought chess to medieval Europe.

[edit] History

In Sanskrit, "Chaturanga" literally means "having four limbs (or parts)" and in epic poetry often means "army". The game reflects four-fold division of the ancient Indian army. Besides the king and his counsellor or general in the center, the army consisted of the following units:

• Infantry represented by a line of advancing pawns.
• Thundering war elephants near the center of the army.
  • Later, this rather weak piece was thought not to be a suitable representation for the power of the real elephant in war in India. This caused a change of move and of name, and often in India nowadays the rook is called the elephant and the bishop is called the camel. (Note: The name Camel is also used for a fairy chess piece with a different move, a (3,1) leaper.)
• Mounted cavalry represented by the horse with a move that facilitated flanking.
• Chariots on the wings which move quickly but linearly and became the rook in Europe, but a ship as chess moved north into Russia.

Chaturanga was played on an 8x8 uncheckered board, called Ashtāpada. The board had some special markers, the meaning of which is unknown today. These markers were not related to chaturanga, but were drawn on the board only by tradition. Some historians^{[citation needed]} have conjectured that the Ashtāpada was also used for some old race-type dice game, perhaps similar to Pachisi, in which these markers had a meaning.

In the ancient Indian epic Mahābhārata (Book 4, Section 1), it says:

And moving upon chess-boards beautiful pawns made of ivory, of blue and yellow and red and white hue, by throws of black and red dice.

This quote may either be referring to an early chess-like game similar to Chaturaji, or a race game such as Pachisi.

Another early reference to a chess-like game includes Subandhu's Vasavadatta (c. 600):

The time of the rains played its game with frogs for chessmen which yellow and green in color, as if mottled by lac, leapt up on the black field squares.

Banabhatta's Harsha Charitha (c. 625) contains the earliest reference to Chaturanga:

Under this king only bees quarrel in collecting dews, the only feet cut off are those in meter, only chess boards teach the positions of the Chaturanga.

[edit] Rules

The exact rules of Chaturanga are not known. However, chess historians believe that the game had the same or very similar rules to Shatranj. Nevertheless, there is uncertainty about move of the Gaja (elephant), the precursor of the Bishop in modern chess.

• Ràja (King); also spelled Raja, Rajah - Moves like the King in chess, as in Shatranj. According to some sources^{[citation needed]}, the Ràja can make one knight-move during the game unless he has already been checked.
• Mantri (Counsellor); also known as Senapati (General) - Moves one square diagonally, like the Fers in Shatranj.
• Ratha (Chariot); also spelled Śakata - Moves like the Rook in chess, as in Shatranj.
• Gaja (Elephant) - Three different moves are described in ancient literature:
  1. Two squares in any diagonal direction, jumping over one square, as the Alfil in Shatranj. This is likely its oldest move.
     • The same move is used for the Boat in a four-handed version of Chaturanga, Chaturaji.
     • The Elephant in Xiangqi (Chinese chess) has the similar move, but without jumping. (The name Elephant is used for a fairy chess piece with this move: a (2,2) leaper, but one that cannot jump over an intervening piece.)
  2. One square forward or one square in any diagonal direction (think of the four legs and trunk of the elephant).
     • This is the same move as the Silver General in Shogi.
     • In Makruk (Thai chess) and Sittuyin (Burmese chess) the elephant moves in the same way.
     • This move was described ca. 1030 by Biruni in his India book.
  3. Two squares in any orthogonal direction, jumping over one square.
     • A piece with such a move is called a Dabbābah in some chess variants. This move was described by the Arabic chess master al-Adli ca. 840 in his (partly lost) chess work. (The Arabic word dabbābah in former times meant a covered siege engine for attacking walled fortifications, and nowadays means "army tank").
       • The German historian Johannes Kohtz (1843-1918) suggests, rather, that this was the earliest move of the Ratha. [1]
• Ashva (Horse); also spelled Ashwa, Asva - Moves like the Knight in chess, as in Shatranj. (This is the distinctive move that marks a game as a likely descendant of Chaturanga.)
• Padàti/Bhata (Foot-soldier); also spelled Pedati, Bhata; also known as Sainik (?Warrior) - Moves like the Pawn in chess, as in Shatranj.

Al-Adli also mentions two further difference to Shatranj:

• Stalemate was a win for a stalemated player. This rule seems to be quite illogical, however it appeared again in some medieval chess variations in England ca. 1600. According to some resources, there was no stalemate, though this is improbable.
• The player, who is first to bare the opponent's king (captures all the pieces except the king), wins. In Shatranj this is also a win, but only in the case that the opponent cannot bare the player's king on the next move in return.
