The History of Backgammon

Ancient Origins: Mesopotamia and the Royal Game of Ur

The roots of backgammon reach back to ancient Mesopotamia, in the region that is now modern Iraq. Archaeological excavations at the city of Ur, conducted by Sir Leonard Woolley in the 1920s, unearthed the Royal Game of Ur, a board game dating to around 3000–2600 BCE. The game used a track-based layout with counters and dice, sharing fundamental mechanics with what would eventually become backgammon.

Similar race-and-capture games appeared independently across ancient civilizations. In Egypt, a game called Senet was played as early as 3500 BCE, depicted in tomb paintings and buried alongside pharaohs as a companion for the afterlife. While Senet's exact rules remain debated, its structure — pieces moving along a linear track according to thrown lots — clearly mirrors the core concept of backgammon.

The Persian and Roman Era

By the time of the Persian Empire (550–330 BCE), a game called Nard was widely played throughout the region. Persian texts describe it as a game of both skill and fortune, with the board representing the calendar: 24 points for the hours of the day, 30 checkers for the days of the month, and the two dice representing fate. This cosmological dimension made Nard not just entertainment but a meditation on destiny.

The Romans absorbed this tradition through their conquests, developing their own version called Ludus Duodecim Scriptorum ("Game of Twelve Lines") and later Tabula. Emperor Claudius was reportedly so fond of the game that he had a special board fitted to his chariot. Roman soldiers spread the game across Europe, from Britain to North Africa, ensuring its survival through the fall of the empire.

The Medieval Period: Tables Games Across Cultures

During the Middle Ages, backgammon-like games flourished under the collective name of Tables in Europe. The game was a fixture in taverns, monasteries, and royal courts alike. King Alfonso X of Castile dedicated an entire section of his encyclopedic Libro de los Juegos (Book of Games, 1283) to tables games, providing some of the earliest detailed written rules.

The Church had a complicated relationship with Tables. It was periodically condemned as a vehicle for gambling and idle behavior, yet clerics themselves were often avid players. Louis IX of France banned the game for his subjects in 1254, though the ban proved largely unenforceable.

Meanwhile, across the Islamic world, the game known as Nard or Tawula continued to thrive. Arab traders and scholars carried it eastward to India and China, westward to Spain and Morocco, weaving the game into the fabric of civilizations on three continents.

Backgammon: The Name is Born

The word backgammon appears in English for the first time in 1645. Its etymology is debated: the most widely accepted theory derives it from the Middle English baec (back) and gamen (game), possibly referring to the frequent return of pieces to the bar. Others suggest a Welsh origin from bach (little) and cammaun (battle).

The 17th century saw the rules of backgammon largely standardized into the form we know today. The game became enormously popular in English coffeehouses, clubs, and drawing rooms, played across all social classes. Gambling on backgammon was common, and the game's mix of skill and chance made it particularly attractive as a betting game.

The Doubling Cube: A 20th-Century Revolution

The most significant rule innovation in backgammon's modern history is the introduction of the doubling cube, which appeared in New York gambling circles in the 1920s. The cube, numbered 2, 4, 8, 16, 32, and 64, allowed players to raise the stakes mid-game, transforming backgammon into a game of complex decision theory and risk assessment.

The doubling cube fundamentally changed the strategic landscape. A player who understands cube equity — when to offer a double, when to accept, when to drop — gains a dramatic advantage over someone who plays purely for the board position. This added layer of depth attracted mathematicians, economists, and game theorists to the game.

The Modern Game and the Rise of Computers

The 1960s and 1970s brought a global backgammon renaissance, centered largely on the jet-set social scene of the Mediterranean and the casinos of Monte Carlo and Las Vegas. Prince Alexis Obolensky, often called the "Father of Modern Backgammon," organized the first major international tournaments starting in 1964, codifying rules and spreading the game's popularity.

The true revolution came in 1992, when Gerald Tesauro at IBM developed TD-Gammon, a neural network trained through self-play that reached world-class strength. TD-Gammon overturned decades of received wisdom about opening moves and positional play, demonstrating that some moves considered weak by human experts were in fact superior. It remains one of the landmark achievements in reinforcement learning.

Today, programs like GNU Backgammon and eXtreme Gammon play far beyond human capability, and serious players use them to analyze their games and identify errors. The World Backgammon Championship, held annually in Monte Carlo, draws hundreds of competitors from around the globe, and online platforms host millions of games every day.

Backgammon Today

Five millennia after the first dice were thrown on a clay board in ancient Mesopotamia, backgammon remains as vital as ever. It is played competitively in more than 60 countries, with national federations organized under the World Backgammon Federation. Its perfect balance of luck and skill — where a beginner can beat an expert on any single game, yet an expert will prevail decisively over a long match — continues to captivate new generations of players around the world.
