How did chess spread around the world?

Chess most likely began in northern India around the sixth century, in a game called chaturanga, whose pieces stood for the parts of an army. From there it moved to Persia, where it became shatranj, then across the Islamic world, into Europe, and eventually everywhere else. Trade routes, conquest and travelers carried it, and each culture changed the rules a little.

What makes the story interesting is how much of it is educated reconstruction. Early evidence is thin, a few written references and some old pieces, and historians still argue about details such as exactly where it started and how it reached China. The rules also changed a lot. The queen, who was once a weak adviser piece, became the most powerful piece on the board in Europe around the late fifteenth century.

An episode on this topic would follow the game along its route, stop to ask what changed and why, and be clear about which parts are well documented and which are guesses. bre's hosts are AI, so they can be wrong, and you can press Talk to ask about any step along the way.

What a bre episode would cover

An outline of the episode bre would make for this question. Every episode is written fresh when you ask, so yours will differ.

  1. Chaturanga: the game in IndiaThe earliest widely accepted ancestor, played on an eight by eight board with pieces modeled on armies. Exactly when and where it began is not certain.
  2. Shatranj in PersiaThe game crossed into Persia, picked up new names and written rules, and became a pastime of courts and scholars.
  3. Across the Islamic worldThrough the Arab conquests and trade, shatranj reached North Africa, Spain and Sicily, and players wrote early books of puzzles and strategy.
  4. Into medieval EuropeChess arrived through Spain, Italy and traders and travelers, and became popular among nobles. Pieces were renamed to fit European society, such as bishops and queens.
  5. The rules that made modern chessAround the late fifteenth century the queen and bishop became far more powerful, making the game faster. This is the version most people play today.
  6. East Asia and the other branchesRelated games such as xiangqi in China and shogi in Japan grew up alongside it. How they connect to chess is debated.
  7. Clubs, clocks and the modern worldPublic clubs, tournaments, timed play, and later computers and the internet helped chess reach millions of people.

How the episode might open

A sample exchange between two of bre’s AI hosts, bre and Cal. Both are AI; this is written by AI, as every bre episode is.

  1. breAI host

    Here's a picture. Somewhere in India, about fifteen hundred years ago, someone sets out little figures that represent an army. Elephants, horses, foot soldiers. That's the ancestor of the game on your shelf.

  2. CalAI host

    Okay, I love that. So it started as a war game? Like a tiny simulation for generals? Because I always assumed chess was just a puzzle, and now I'm thinking it was basically the first strategy training tool.

  3. breAI host

    Maybe, though I'd be careful. We know it modeled armies. Whether anyone used it to train generals, I don't know. The evidence is thin.

  4. CalAI host

    Fair. So how thin are we talking? Like a pile of documents, or a couple of broken pieces and a lot of guessing?

  5. breAI host

    Closer to the second. A few written references, some old pieces, and historians who still argue about the details. What's solid is the route: India, Persia, the Islamic world, then Europe.

  6. CalAI host

    Hold on, how does that actually work? A game doesn't have a passport. Who's carrying it across all those borders?

  7. breAI host

    Merchants, diplomats, soldiers, scholars. Anyone who sat down with someone from somewhere else and had time to kill. And every time it crossed a border, somebody tweaked the rules.

  8. CalAI host

    So the chess I play is basically a game of telephone that ran for a thousand years.

Questions people also ask

Where did chess originate?
Most historians trace it to northern India around the sixth century, to a game called chaturanga. Some have proposed other origins, and the early evidence is limited, so the exact place and date remain uncertain, but India is the most widely accepted answer.
How did chess get to Europe?
It passed from Persia into the Islamic world, then reached Europe through contact in places like Spain and Sicily, as well as through trade and travel. By the medieval period it was popular among nobles, and pieces were renamed to fit European society.
When did the queen become the strongest piece?
Around the late fifteenth century, European players changed the rules so the queen and bishop could move much farther. The older versions of these pieces were weak. Exactly where and how fast the change spread is still discussed by historians.
Is xiangqi the same as chess?
No. Xiangqi is Chinese chess, with a different board, different pieces and different rules. It is related to the same family of games, but how closely and by which route is debated by historians.
