Who Invented Mahjong? Five Suspects and One Very Patient Sailor

A philosopher, a port official, two brothers, an army camp and a Shanghai noble all get the credit. The honest answer is stranger than any of them.

Ask where mahjong came from and someone will tell you Confucius invented it around 500 BC. It is a wonderful story: the three dragon tiles stand for his cardinal virtues, and the game's name (sparrow, in the old rendering) honours his love of birds. It is also, as far as any historian can find, completely made up. There is no evidence of mahjong existing before the 19th century, and the Confucius story seems to have been polished up later, largely because "ancient Chinese game" sold sets.

The card games that came first

What mahjong actually descends from is paper. Ming-dynasty card games like Yezi ("leaf") and Madiào were played with money-suited cards: coins, strings of coins, and ten-thousands of strings. Their descendant Peng He Pai carried three suits in repeated sets — and when the cards became tiles, the suits simply changed costume: coins became dots, strings of coins became bamboos, and the ten-thousand suit became the characters American players call "craks." Most of a mahjong tile is a playing card that put on weight.

Suspect one: Chen Yumen of Ningbo

The best-documented candidate is Chen Yumen, a Qing-dynasty official from the port city of Ningbo, in the Taiping Rebellion era of the 1850s and 1860s. He is credited with adding the red dragon tile and the winds to the old card game, and with the most practical innovation of all: having the cards carved as bone-and-bamboo tiles because, the story goes, a sailor's paper deck kept blowing into the sea. Chen spoke English, and in 1861 he taught the game to the British consul F. E. B. Harvey — whose letters home are among the earliest written records of mahjong anywhere.

Suspects two through five

Chen has rivals. One tradition credits two brothers in Ningbo around 1850, adapting Madiào on their own. Another says Taiping army officers invented it to pass camp time. A fourth theory gives it to a Shanghai-area noble between 1870 and 1875. And a colleague of Chen's, Chang Shiu-Mo, is sometimes credited with adding the flowers and seasons. The rivals cannot all be right, and the surviving evidence, early tile sets dated to roughly 1868–1876, does not quite match any modern set: the game was still mutating in the box.

The honest verdict

Mahjong almost certainly has no single inventor. It precipitated out of a family of card games in one port city over a few decades, with Chen Yumen as the most plausible single contributor and the Confucius story as marketing invented after the fact. That is less romantic than a philosopher at a tile wall, but it explains the thing players notice today: a game born by committee, in a port, was always going to splinter into local versions the moment it travelled. Which is exactly what happened next.

Put the story to use

However it started, the tiles changed less than the rules did. Compare the three big modern games in American vs Chinese vs Riichi, or browse the sets we stock guides for.
