Origins of baseball in the context of "Rounders"

Throughout the history of baseball, the rules of the game have changed frequently as the game continues to evolve. A few typical rules that most professional leagues have in common are that four balls are a base on balls, three strikes are a strikeout, and three outs end a half-inning.

Baseball evolved out of bat-and-ball games in the mid-19th century, and its modern rules are based mainly on those first published in 1848. Most rule sets are generally based on the Official Baseball Rules (OBR) published by Major League Baseball (MLB), though various minor variations exist from league to league; the World Baseball Softball Confederation maintains its own official rule set for international competition.

The National Baseball Hall of Fame and Museum is a history museum and hall of fame in Cooperstown, New York, operated by a private foundation. It serves as the central collection and gathering space for the history of baseball in the United States displaying baseball-related artifacts and exhibits, honoring those who have excelled in playing, managing, and serving the sport. The Hall's motto is "Preserving History, Honoring Excellence, Connecting Generations". Cooperstown is often used as shorthand (or a metonym) for the National Baseball Hall of Fame and Museum. The museum also established and manages the process for honorees into the Hall of Fame.

The Hall of Fame was established in 1939 by Stephen Carlton Clark, heir to the Singer Sewing Machine fortune. Clark sought to bring tourists to the village hurt by the Great Depression, which reduced the local tourist trade, and Prohibition, which devastated the local hops industry. Clark constructed the Hall of Fame's building, which was dedicated on June 12, 1939. (His granddaughter, Jane Forbes Clark, is the current chairman of the board of directors.) The mythology that future Civil War hero Abner Doubleday invented baseball in Cooperstown in the 1830s was instrumental in the placement and early marketing of the Hall.

The Knickerbocker Rules are a set of baseball rules formalized by William R. Wheaton and William H. Tucker of the Knickerbocker Base Ball Club in 1845. They have previously been considered to be the basis for the rules of the modern game, although this is disputed. The rules are informally known as the "New York style" of baseball, as opposed to other variants such as the "Massachusetts Game" and "Philadelphia town ball".

The history of baseball can be broken down into various aspects: by era, by locale, by organizational-type, game evolution, as well as by political and cultural influence. The game evolved from older bat-and-ball games already being played in England by the mid-18th century. These games were taken to North America by immigrants, where the modern version developed. By the late 19th century, baseball was widely recognized as the national sport of the United States, and had begun to spread throughout the Pacific Rim and the Americas. Today, baseball is popular in North America and parts of Central and South America, the Caribbean, and East Asia, particularly in Japan, South Korea, and Taiwan.

References to baseball date back to the 1700s when in England it was referenced in 1744 in the children's book A Little Pretty Pocket-Book by John Newberry. The game is also mentioned in the book Northanger Abbey by Jane Austen, published in 1818. In the early 1800s "baseball" and a game first mentioned in 1828 as the aforementioned "rounders" may have been the same or very similar. During the 1830s and 1840s organized amateur club baseball grew up in eastern United States cities; however, the first official baseball game with a documented score card took place not in the US, but in Canada in 1838. While Canada invented the version of baseball we know today, innovations made by New York City clubs became the basis for the modern game, far removed from its English ancestor, but extremely similar to the Canadian version. These clubs formed a national governing body with uniform rules in 1858, the National Association of Base Ball Players. In 1871 the first professional league, the National Association of Professional Base Ball Players, was founded. Five years later, the National League was created; it was followed by the American League in 1901. The first World Series between the champions of the two major leagues was held in 1903, and by 1905 it became an annual event. Baseball early in the 20th century was characterized by low-scoring games, but the dead-ball era ended in the early 1920s with rule changes and the rise of power hitter Babe Ruth. The major leagues had a color barrier that lasted until 1947, when Jackie Robinson made his debut. The major leagues began the process of expansion in 1961 and attendance increased from the mid-1970s to 1994, when a work stoppage led to the cancellation of the World Series.
