The evolution of baseball from older bat-and-ball games is difficult to trace with precision. Consensus once held that today’s baseball is a North American development from the older game rounders, popular among children in Great Britain and Ireland. American baseball historian David Block suggests that the game originated in England; recently uncovered historical evidence supports this position. Block argues that rounders and early baseball were actually regional variants of each other, and that the game’s most direct antecedents are the English games of stoolball and “tut-ball”. The earliest known reference to baseball is in a 1744 British publication, A Little Pretty Pocket-Book, by John Newbery. Block discovered that the first recorded game of “Bass-Ball” took place in 1749 in Surrey, and featured the Prince of Wales as a player. This early form of the game was apparently brought to Canada by English immigrants.
By the early 1830s, there were reports of a variety of uncodified bat-and-ball games recognizable as early forms of baseball being played around North America. The first officially recorded baseball game in North America was played in Beachville, Ontario, Canada, on June 4, 1838. In 1845, Alexander Cartwright, a member of New York City’s Knickerbocker Club, led the codification of the so-called Knickerbocker Rules, which in turn were based on rules developed in 1837 by William R. Wheaton of the Gotham Club. While there are reports that the New York Knickerbockers played games in 1845, the contest long recognized as the first officially recorded baseball game in U.S. history took place on June 19, 1846, in Hoboken, New Jersey: the “New York Nine” defeated the Knickerbockers, 23–1, in four innings. With the Knickerbocker code as the basis, the rules of modern baseball continued to evolve over the next half-century. By the time of the Civil War, baseball had begun to overtake its fellow bat-and-ball sport cricket in popularity within the United States, due in part to baseball being of a much shorter duration than the form of cricket played at the time, as well as the fact that troops during the Civil War did not need a specialized playing surface to play baseball, as they would have required for cricket.

Establishment of professional leagues
In the mid-1850s, a baseball craze hit the New York metropolitan area, and by 1856, local journals were referring to baseball as the “national pastime” or “national game”.[57] A year later, the sport’s first governing body, the National Association of Base Ball Players, was formed. In 1867, it barred participation by African Americans. The more formally structured National League was founded in 1876. Professional Negro leagues formed, but quickly folded. In 1887, softball, under the name of indoor baseball or indoor-outdoor, was invented as a winter version of the parent game. The National League’s first successful counterpart, the American League, which evolved from the minor Western League, was established in 1893, and virtually all of the modern baseball rules were in place by then.
The National Agreement of 1903 formalized relations both between the two major leagues and between them and the National Association of Professional Base Ball Leagues, representing most of the country’s minor professional leagues The World Series, pitting the two major league champions against each other, was inaugurated that fall. The Black Sox Scandal of the 1919 World Series led to the formation of the office of the Commissioner of Baseball. The first commissioner, Kenesaw Mountain Landis, was elected in 1920. That year also saw the founding of the Negro National League; the first significant Negro league, it would operate until 1931. For part of the 1920s, it was joined by the Eastern Colored League.
Rise of Ruth and racial integration
Compared with the present, professional baseball in the early 20th century was lower-scoring, and pitchers were more dominant.[68] The so-called dead-ball era ended in the early 1920s with several changes in rule and circumstance that were advantageous to hitters. Strict new regulations governed the ball’s size, shape and composition, along with a new rule officially banning the spitball and other pitches that depended on the ball being treated or roughed-up with foreign substances, resulted in a ball that traveled farther when hit. The rise of the legendary player Babe Ruth, the first great power hitter of the new era, helped permanently alter the nature of the game.[70] In the late 1920s and early 1930s, St. Louis Cardinals general manager Branch Rickey invested in several minor league clubs and developed the first modern farm system. A new Negro National League was organized in 1933; four years later, it was joined by the Negro American League. The first elections to the National Baseball Hall of Fame took place in 1936. In 1939, Little League Baseball was founded in Pennsylvania.

A large number of minor league teams disbanded when World War II led to a player shortage. Chicago Cubs owner Philip K. Wrigley led the formation of the All-American Girls Professional Baseball League to help keep the game in the public eye. The first crack in the unwritten agreement barring blacks from white-controlled professional ball occurred in 1945: Jackie Robinson was signed by the National League’s Brooklyn Dodgers and began playing for their minor league team in Montreal. In 1947, Robinson broke the major leagues’ color barrier when he debuted with the Dodgers. Latin-American players, largely overlooked before, also started entering the majors in greater numbers. In 1951, two Chicago White Sox, Venezuelan-born Chico Carrasquel and black Cuban-born Minnie Miñoso, became the first Hispanic All-Stars. Integration proceeded slowly: by 1953, only six of the 16 major league teams had a black player on the roster.

Attendance records and the age of steroids
In 1975, the union’s power—and players’ salaries—began to increase greatly when the reserve clause was effectively struck down, leading to the free agency system. Significant work stoppages occurred in 1981 and 1994, the latter forcing the cancellation of the World Series for the first time in 90 years. Attendance had been growing steadily since the mid-1970s and in 1994, before the stoppage, the majors were setting their all-time record for per-game attendance. After play resumed in 1995, non-division-winning wild card teams became a permanent fixture of the post-season. Regular-season interleague play was introduced in 1997 and the second-highest attendance mark for a full season was set. In 2000, the National and American Leagues were dissolved as legal entities. While their identities were maintained for scheduling purposes (and the designated hitter distinction), the regulations and other functions—such as player discipline and umpire supervision—they had administered separately were consolidated under the rubric of MLB.
In 2001, Barry Bonds established the current record of 73 home runs in a single season. There had long been suspicions that the dramatic increase in power hitting was fueled in large part by the abuse of illegal steroids (as well as by the dilution of pitching talent due to expansion), but the issue only began attracting significant media attention in 2002 and there was no penalty for the use of performance-enhancing drugs before 2004. In 2007, Bonds became MLB’s all-time home run leader, surpassing Hank Aaron, as total major league and minor league attendance both reached all-time highs.
Around the world
With the historic popular moniker as “America’s national pastime”, baseball is well established in several other countries as well. As early as 1877, a professional league, the International Association, featured teams from both Canada and the US. While baseball is widely played in Canada and many minor league teams have been based in the country, the American major leagues did not include a Canadian club until 1969, when the Montreal Expos joined the National League as an expansion team. In 1977, the expansion Toronto Blue Jays joined the American League.

In 1847, American soldiers played what may have been the first baseball game in Mexico at Parque Los Berros in Xalapa, Veracruz. The first formal baseball league outside of the United States and Canada was founded in 1878 in Cuba, which maintains a rich baseball tradition. The Dominican Republic held its first islandwide championship tournament in 1912. Professional baseball tournaments and leagues began to form in other countries between the world wars, including the Netherlands (formed in 1922), Australia (1934), Japan (1936), Mexico (1937), and Puerto Rico (1938). The Japanese major leagues have long been considered the highest quality professional circuits outside of the United States.
Pesäpallo, a Finnish variation of baseball, was invented by Lauri “Tahko” Pihkala in the 1920s, and after that, it has changed with the times and grown in popularity. Picture of Pesäpallo match in 1958 in Jyväskylä, Finland.
After World War II, professional leagues were founded in many Latin American countries, most prominently Venezuela (1946) and the Dominican Republic (1955). Since the early 1970s, the annual Caribbean Series has matched the championship clubs from the four leading Latin American winter leagues: the Dominican Professional Baseball League, Mexican Pacific League, Puerto Rican Professional Baseball League, and Venezuelan Professional Baseball League. In Asia, South Korea (1982), Taiwan (1990) and China (2003) all have professional leagues.
The English football club, Aston Villa, were the first British baseball champions winning the 1890 National League of Baseball of Great Britain. The 2020 National Champions were the London Mets. Other European countries have seen professional leagues; the most successful, other than the Dutch league, is the Italian league, founded in 1948. In 2004, Australia won a surprise silver medal at the Olympic Games. The Confédération Européene de Baseball (European Baseball Confederation), founded in 1953, organizes a number of competitions between clubs from different countries. Other competitions between national teams, such as the Baseball World Cup and the Olympic baseball tournament, were administered by the International Baseball Federation (IBAF) from its formation in 1938 until its 2013 merger with the International Softball Federation to create the current joint governing body for both sports, the World Baseball Softball Confederation (WBSC). Women’s baseball is played on an organized amateur basis in numerous countries.
