How a battlefield game from ancient India crossed Persia, the Islamic world and medieval Europe, gained a “mad” queen, crowned world champions, faced the computers — and became the game hundreds of millions play online today.
Start the journey ↓Most historians trace chess to northern India around the 6th century CE, during or just after the Gupta Empire. The game was called chaturanga, a Sanskrit word for the “four limbs” of an ancient Indian army: infantry, cavalry, elephants and chariots. Those four divisions became the pawns, knights, bishops and rooks we still play with.
Chaturanga was probably played on the ashtāpada, an 8×8 board already used for race games. Each side had a king (raja) and a counsellor (mantri) beside him. The pieces moved more slowly than today, and games were long manoeuvring battles — but the key idea was already there: the aim is not to capture everything, but to trap the king.
Other theories place the game’s origin in China or Central Asia, and related games such as xiangqi in China and shogi in Japan developed along their own paths. But the line of descent from chaturanga to modern chess is the best documented.
A famous legend links chess to India too. A wise man is said to have invented the game for a king, asking as his reward one grain of rice on the first square, two on the second, four on the third, doubling each time. The king laughed at the modest request — until his advisers calculated that the total for all 64 squares was more rice than existed in the world. True or not, the story shows how early chess became a symbol of clever thinking.
From India the game travelled to Sasanian Persia, where it was called chatrang. A Middle Persian text tells the story of an Indian king sending the game to the Persian court as a challenge — and of a Persian sage who solved its secrets.
Persia gave chess much of its vocabulary. The king was the shāh, and players warned “shāh!” when the king was attacked — the origin of the word check. When the king was trapped, they said shāh māt, roughly “the king is helpless” — the origin of checkmate. The Persian rukh became our rook.
Persian poets used chess as a metaphor for fate and life, and stories of kings, sages and chessboards appear in the great Persian epic, the Shahnameh, completed by Ferdowsi around the year 1010. In Persia the game also became a mark of education: a cultured courtier was expected to play well, alongside horsemanship, poetry and music.
After the Arab conquest of Persia in the 7th century, the game — now called shatranj — spread rapidly across the Islamic world, from Baghdad to Cordoba. Under the Abbasid caliphs it became a serious intellectual pursuit, with ranked masters, written theory and the first chess books.
Players such as al-Adli, ar-Razi and above all as-Suli in the 10th century analysed openings and endgames and composed mansūbāt — chess problems, many of which can still be solved today. Pieces were often abstract shapes rather than carved animals and people.
Shatranj was slower than modern chess. The firzān (counsellor) moved just one square diagonally, and the alfil (elephant) jumped exactly two squares diagonally. Winning often meant capturing all the opponent’s pieces except the king — a rule called “baring the king”.
Chess also gave the Islamic world some of its first written “theory”. Players named and recorded opening set-ups, called ta‘biyat, and classified players by strength — an early ancestor of modern ratings. Many of the stories that later reached Europe, such as the legend of the rice on the chessboard, travelled with shatranj along the same trade routes.
Chess reached Europe by around the year 1000, through Muslim Spain (al-Andalus), Sicily and the Byzantine Empire, and along trade routes into Scandinavia and Russia. A Latin poem from around the end of the 10th century is among the earliest European references to the game.
Europeans reshaped the pieces to fit their own world. The counsellor became a queen; the elephant became a bishop in England, a “fool” (fou) in France and a “runner” (Läufer) in Germany; the horse became a knight. The board gained its familiar light and dark squares.
Chess became part of a noble education. The famous Lewis chessmen, carved from walrus ivory in the 12th century and found on a Scottish island in 1831, show grim-faced kings, queens, bishops and berserker warriors biting their shields. In 1283 King Alfonso X of Castile commissioned a beautifully illustrated Book of Games full of chess problems.
The Church did not always approve — chess was sometimes linked with gambling and banned for clergy — but the game survived and flourished. It appeared in sermons, poems and romances, where kings and knights played it as a test of wit. By the late Middle Ages chess was one of the most popular games in Europe, played by monarchs, merchants and monks alike.
In the late 15th century — probably in Spain or Italy — the rules changed dramatically. The queen, until then one of the weakest pieces, suddenly gained the power to move any distance in a straight line or diagonal. The bishop also became a long-range piece, and pawns could move two squares on their first move.
Contemporaries called it “queen’s chess” or even “mad queen chess”. Games became faster and far more tactical: a single mistake in the opening could now lose in a few moves. A Catalan poem from around 1475 describes one of the first games under the new rules, and in 1497 Luis Ramírez de Lucena published one of the earliest printed chess books in Salamanca.
Some rules took centuries to settle. Castling and en passant capture were standardised only gradually, and Italy kept its own castling rules until the 19th century. But by 1500 the game was recognisably modern chess.
The new rules spread remarkably quickly. Within a few decades the powerful queen was standard across Spain, Italy and France, and within a century the slower medieval game had almost disappeared. Some historians link the queen’s new power to the strong queens of the age, such as Isabella I of Castile, though the true reason is unknown.
With the printing press, chess knowledge spread quickly. In 1561 the Spanish priest Ruy López de Segura published a book of openings — his name lives on in the Ruy Lopez (1.e4 e5 2.Nf3 Nc6 3.Bb5). Italian masters such as Leonardo da Cutri and Paolo Boi travelled to play for wealthy patrons, and in the early 1600s Gioachino Greco wrote down sparkling attacking games that were copied for centuries.
In the 18th century chess moved into coffeehouses. The Café de la Régence in Paris and Slaughter’s Coffee House in London became the centres of the chess world. There François-André Danican Philidor, also a famous composer, dominated play and in 1749 published a book arguing that pawns are the key to every position — the first great work of chess strategy.
This was also the age of the first chess celebrities. Spanish and Italian masters played famous matches at the court of King Philip II of Spain in the 1570s, and wealthy patrons sponsored travelling players. Openings such as the Italian Game and the King’s Gambit were analysed in detail, and many of their names come from this period.

The 19th century was the age of Romantic chess: daring gambits, piece sacrifices and direct attacks on the king. Great matches between France’s Louis-Charles de La Bourdonnais and Ireland’s Alexander McDonnell in 1834, and between Howard Staunton and Pierre de Saint-Amant in 1843, drew huge public interest.
In 1849 a clear, sturdy chess set design was released in London with Staunton’s endorsement. The Staunton pattern — crowned king, mitred bishop, horse-head knight — became the standard used in every tournament today. In 1851 Staunton organised the first international tournament in London, won by Adolf Anderssen, who that same year played the dazzling “Immortal Game”.
Then came Paul Morphy of New Orleans, who in 1857–59 beat every leading player he met in America and Europe before retiring. Chess columns appeared in newspapers, chess problems became an art form, and mechanical chess clocks were introduced to keep tournament games moving.
The era also produced chess’s first great writers and organisers. Clubs and national associations were founded, the first chess magazines appeared, and correspondence chess let players compete by post across countries. By the 1880s the game had a calendar of international tournaments and a growing group of professional players — everything needed for an official world champion.

In 1886 Wilhelm Steinitz beat Johannes Zukertort in the first official world championship match. Steinitz taught that small, lasting advantages decide games — the beginning of positional chess. Emanuel Lasker then reigned for 27 years, followed by the clear, effortless José Raúl Capablanca and the brilliant attacker Alexander Alekhine.
In the 1920s the “hypermoderns”, led by Aron Nimzowitsch and Richard Réti, challenged the old rules and showed that the centre can be controlled from a distance. In 1924 the international chess federation, FIDE, was founded in Paris, and in 1927 the first official Chess Olympiad and the first Women’s World Championship — won by Vera Menchik — were held in London.
During this period chess also became organised for everyone. National championships, junior events and club leagues spread across Europe and the Americas, and chess books in many languages taught openings, tactics and endgames to ordinary players. Radio, newspapers and cables carried the moves of big matches around the world within hours.

After Alekhine’s death, Mikhail Botvinnik won the title in 1948 and began an era in which Soviet players dominated. The state supported chess schools, trainers and tournaments, and players such as Smyslov, Tal, Petrosian and Spassky took turns at the top.
In 1972 the American Bobby Fischer beat Boris Spassky in Reykjavík in the “Match of the Century”, followed around the world at the height of the Cold War. Around the same time, FIDE adopted Arpad Elo’s rating system (1970), giving every player a number that measures their strength — the system behind the ratings you see on chess sites today.
The 1980s belonged to the epic rivalry between Anatoly Karpov and Garry Kasparov, who played five world championship matches between 1984 and 1990.
Outside the Soviet Union, chess grew too. Grandmasters from Hungary, Yugoslavia, the Netherlands, Denmark and Argentina competed at the top, and Fischer’s victory sparked a chess boom in the United States and western Europe. Women’s chess advanced as well, with Georgian players such as Nona Gaprindashvili and Maia Chiburdanidze dominating the women’s world championship for decades.
Computer pioneers saw chess as the perfect test of machine intelligence. In 1950 Claude Shannon published a famous paper on programming a computer to play chess, and Alan Turing wrote a chess algorithm he had to run by hand with paper and pencil.
Programs improved steadily, and in 1997 IBM’s Deep Blue beat world champion Garry Kasparov in a six-game match — a landmark moment for artificial intelligence. Today free engines such as Stockfish play far stronger than any human, and in 2017 DeepMind’s AlphaZero taught itself chess from the rules alone and found a fresh, creative style.
For players, engines changed everything: anyone can now check their games with world-class analysis. ChessStride runs the Stockfish engine right in your browser to review your games and build training from your own mistakes.
Engines also changed opening theory forever. Lines that humans had trusted for a century were refuted, forgotten ideas were revived, and top players now prepare with neural-network engines that evaluate positions more like a human intuition than a simple calculator. Yet humans still play humans: the machines became training partners, not replacements.
From the mid-1990s, internet servers let players find an opponent at any hour. Big platforms followed, and by the 2010s millions played every day on phones and computers. Faster time controls, puzzles and streaming made chess more social than ever.
In 2020, with people at home during the pandemic and the hit drama The Queen’s Gambit on screens worldwide, chess exploded in popularity. Streamers and online events brought top players to huge new audiences.
Chess is now truly global. India, inspired by Viswanathan Anand, has become a superpower: Gukesh Dommaraju became the youngest undisputed world champion in 2024, and India won both the open and women’s gold medals at the 2024 Olympiad. Today hundreds of millions of people play — and every one of them is part of a story that began on an Indian battlefield board some 1,500 years ago.
Online play also changed how people learn. Puzzles, interactive lessons, opening explorers and instant game reviews are available to anyone with a phone, and children in villages and cities alike can now play opponents from other continents. Variants such as Chess960 and new formats such as fast online arenas keep the game fresh — while the classical game, with its 1,500-year history, remains as deep as ever.
Chess most likely began in northern India around the 6th century CE as chaturanga, a game representing the four divisions of an army. It then spread to Persia, the Islamic world and Europe.
The game in a form recognisable as the ancestor of chess is about 1,500 years old. Modern rules — with the powerful queen and long-range bishop — date from the late 15th century.
Around 1475–1500 in Spain or Italy. Before that, the queen (originally the counsellor) could move only one square diagonally.
