History of Chess: From 6th-Century India to the Modern Game

Chess was invented in India sometime in the 5th or 6th century CE, most likely in the Gupta period. The earliest form was called chaturanga, Sanskrit for “four divisions”, referring to the four branches of the Indian military: infantry, cavalry, elephants, and chariots. These became, through Arabic and Persian transmission, the pawns, knights, bishops, and rooks of the modern game.

The transition from that game to the chess played in the 2024 World Chess Championship between Gukesh Dommaraju and Ding Liren took roughly 1,400 years. The basic structure (two armies, one king per side, capture and checkmate) has held throughout. The pieces, the board size, and the specific movement rules changed substantially in the first millennium of the game’s existence, then stabilized. What we play today was essentially set by the early 16th century.

Chaturanga: the Indian original

The earliest written references to chaturanga date to the late 6th century CE. The game was played on an 8×8 board, the same dimensions as the modern game, with pieces representing the components of the classical Indian army.

The key pieces: a raja (king), a mantri (counselor, now the queen), ratha (chariot, now the rook), gaja (elephant, now the bishop), ashva (horse, now the knight), and padati (foot soldier, now the pawn). Movement rules differed significantly from modern chess: the mantri moved one square diagonally; the elephant moved two squares diagonally; the game had no castling, no en passant, no two-square pawn opening move.

The primary scholarly work on chess history is H.J.R. Murray’s A History of Chess (1913), still the most comprehensive source available. Murray traced the game’s geographic spread through manuscript evidence and cross-referencing with Arab and Persian references that cite Indian origin explicitly.

Shatranj: the Persian and Arab transmission

The game spread from India to Persia, probably in the late 6th century. The Persian word for chess (chatrang, later shatranj) derives from the Sanskrit chaturanga. Persian sources from the 6th and 7th centuries reference the game as coming from India. The Shahnameh of Ferdowsi (c. 1000 CE), the Persian national epic, includes an account of chess arriving in Persia as a gift from the Indian king.

Under Arab rule following the 7th-century Islamic conquests, shatranj became widespread across the Islamic world. Arab players developed a rich theoretical tradition, manuscripts survive describing opening analysis, endgame theory, and tactical themes. The Arabic term “shah mat” (the king is helpless/dead) became “checkmate” in European languages.

The queen in shatranj was the firz (counselor) and moved one square diagonally: a weak piece by modern standards. The bishop was the fil (elephant) and moved two squares diagonally, jumping over intermediate squares. Neither piece had the range and power they have today.

Entry into Europe: 9th to 11th centuries

Chess reached Europe through two main routes: the Arab conquest of Spain (711 CE) and Mediterranean trade via Sicily and southern Italy. The earliest European chess pieces date to approximately the 9th century. The game spread rapidly among the nobility and clergy.

The Lewis Chessmen (carved from walrus ivory and whale teeth, discovered on the Isle of Lewis in Scotland in 1831) date to approximately 1150–1200 CE. They’re one of the most complete surviving examples of medieval European chess pieces and show a game already recognizable: bishops, knights, rooks with towers. The pieces’ appearance reflects European feudal hierarchy, not the original Indian military structure.

The 15th-century revolution

The most important changes in chess history happened in 15th-century Spain and Italy. Two rules transformed the game:

The queen became powerful. The firz/mantri moved one square diagonally; the new queen moved any number of squares in any direction: diagonally, horizontally, or vertically. This single change made the game dramatically faster and more tactical.

The bishop gained range. The fil/elephant moved two squares diagonally, jumping pieces; the new bishop moved any number of squares diagonally. Combined with the powerful queen, the resulting game had far more dynamic attacking possibilities.

Other changes: pawns got the option to move two squares on their first move (creating en passant), castling was introduced, and the promotion rule was standardized.

The earliest printed chess book, Luis Ramírez de Lucena’s Repetición de Amores y Arte de Ajedrez (c. 1497), describes the new rules. Ruy López de Segura’s 1561 treatise, which introduced the Ruy Lopez opening that bears his name, discusses the new game as established.

Standardization: 18th and 19th centuries

The final standardization came in the 18th and 19th centuries, particularly through European club chess. The Staunton design for chess pieces, proposed by Howard Staunton and published by Nathaniel Cook in 1849, became the international standard. Before Staunton, chess sets varied wildly by country and maker; a player traveling between France and England might find pieces they couldn’t identify.

The first international chess tournament was held in London in 1851. The same tournament where Adolf Anderssen played the Immortal Game. The first World Chess Championship match followed in 1886: Steinitz vs. Zukertort, establishing the championship lineage that runs to Gukesh’s 2024 title.

Frequently asked questions

Where was chess invented? India, most likely in the 5th or 6th century CE during the Gupta period. The original game was called chaturanga, referring to the four divisions of the Indian military.

How old is chess? The earliest written references to chaturanga date to the late 6th century CE: roughly 1,400 years ago. The game reached its modern form with the 15th-century Spanish/Italian rule changes, making the current version of chess about 500 years old.

Who invented the chess queen? The powerful queen emerged from 15th-century European rule changes, probably in Spain or Italy. The original piece (the mantri/firz) moved one square diagonally. The change to “any number of squares in any direction” is undocumented as a single person’s invention: it developed through practice across multiple regions.

What is the difference between chess and chaturanga? The board size (8×8) is the same. In chaturanga: the queen (mantri) moved one square diagonally, the bishop (elephant) jumped two squares diagonally, there was no castling, no en passant, and no two-square pawn opening move. Modern chess acquired these features in the 15th century.
