Baseball history

A modicum of peace was eventually established, leading to the National Agreement of 1903. The pact 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 National Baseball Commission was created to oversee Organized Baseball. The World Series, pitting the two major league champions against each other, was inaugurated that fall, albeit without express major league sanction: The Boston Americans of the American League defeated the Pittsburgh Pirates of the National League. The next year, the series was not held, as the National League champion New York Giants, under manager John McGraw, refused to recognize the major league status of the American League and its champion. In 1905, the Giants were National League champions again and team management relented, leading to the establishment of the World Series as the major leagues' annual championship event.

As professional baseball became increasingly profitable, players frequently raised grievances against owners over issues of control and equitable income distribution. During the major leagues' early decades, players on various teams occasionally attempted strikes, which routinely failed when their jobs were sufficiently threatened. In general, the strict rules of baseball contracts and the reserve clause, which bound players to their teams even when their contracts had ended, tended to keep the players in check. Motivated by dislike for particularly stingy owner Charles Comiskey and gamblers' payoffs, real and promised, members of the Chicago White Sox conspired to throw the 1919 World Series. The Black Sox Scandal led to the dissolution of the National Baseball Commission and 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.
