The Origins of Baseball: Myth, History, and How America's Pastime Actually Evolved

The Doubleday Myth — and Why It Stuck

Ask most Americans who invented baseball and a surprising number will say Abner Doubleday — a Civil War general who supposedly laid out the first diamond in Cooperstown, New York, in 1839. The story is tidy, patriotic, and almost entirely fictional.

The Doubleday origin story was popularized by the Mills Commission, a panel convened in 1907 by sporting goods entrepreneur Albert Spalding to settle a long-running debate about whether baseball was American-born or descended from English games. The commission relied heavily on a single letter from a man named Abner Graves, who claimed to have witnessed Doubleday's invention as a child. Historians have since noted that Graves was elderly, the letter was uncorroborated, and Doubleday himself never mentioned baseball in any of his extensive writings.

The myth persisted because it served a purpose: it gave the sport a clean founding moment and a national hero. Cooperstown became the home of the Baseball Hall of Fame largely on the strength of that story — though the Hall opened in 1939, well after scholars had begun questioning the commission's findings.

What the Historical Record Actually Shows

Baseball almost certainly evolved from older English bat-and-ball games — particularly rounders and a game simply called base ball, references to which appear in English literature as far back as the 18th century. A 1744 children's book, A Little Pretty Pocket-Book, includes an illustration of a game called "base-ball" with players, a pitcher, and bases arranged in a pattern.

By the early 1800s, informal versions of the game were being played across the northeastern United States. Rules varied town by town. Then in 1845, a New York volunteer fire company called the Knickerbocker Base Ball Club — often credited to Alexander Cartwright — codified a set of rules that moved the game meaningfully toward its modern form: foul lines, three-strike outs, and the elimination of the practice of retiring a runner by hitting them with a thrown ball (called "soaking").

The game spread rapidly after the Civil War, when soldiers from different regions had played together and carried a more standardized version home. By 1869, the Cincinnati Red Stockings had become the first openly all-professional team, and the National League followed in 1876. If you want to understand the strategy built on top of these rules, our guide for first-time viewers walks through how the modern game actually unfolds.

Understanding Baseball's Evolution in Context

Compared to sports with documented inventors — basketball was formally designed by Dr. James Naismith in 1891 — baseball's origins are diffuse and democratic. No single person sat down and invented it. That makes its history more accurate but less mythically satisfying, which is exactly why the Doubleday story filled a void.

The sport also reflects broader American social history in ways the legend obscures. The Negro Leagues, founded in the early 20th century after Black players were systematically excluded from the major leagues, produced exceptional athletes and contributed innovations to the game itself. Baseball's integration in 1947 with Jackie Robinson joining the Brooklyn Dodgers was a pivotal cultural moment, not just a sports one.

Some of the rules that emerged from this long evolution can still trip up fans today — for context on how specific regulations developed and why they exist, see this breakdown of baseball's most confusing rules. For comparison, the NBA's history shows how a sport with a known inventor still took decades to reach its current form — suggesting that even clear origins don't guarantee a smooth path to the modern game.

What baseball actually is — a game refined by countless players, administrators, and communities over two centuries — is a richer story than any single founding myth could capture.
