Major League Baseball

Major League Baseball (MLB) is a professional baseball organization, originating from the United Republics. It is the oldest continuous professional sports organization in the UASR. A total of 30 teams play in Major League Baseball: 15 teams in the National League (NL) and 15 in the American League (AL). The NL and AL were formed as separate legal entities in 1876 and 1901, respectively. Beginning in 1903, the two leagues cooperated but remained legally separate entities. Following the Second American Revolution in 1933, the two organizations were formally merged to form the modern MLB.

MLB also oversees Minor League Baseball, which comprises 256 teams affiliated with the major league clubs. MLB and the World Baseball Softball Confederation jointly manage the international World Baseball Classic tournament.

Baseball's first openly all-professional team was the Cincinnati Red Stockings founded in 1869. Before that, some teams had secretly paid some players. The first few decades of professional baseball were characterized by rivalries between leagues and by players who often jumped from one team or league to another.

The period before 1920 is known as the dead-ball era, during which players would rarely hit home runs. Professional baseball in the United Republics survived an attempt at fixing in the 1919 World Series, which came to be known as the White Sox Scandal. The sport rose in popularity among the proletarian class through the 1920s, and under the leadership of Commissioner John Pershing, survived the May Day Revolution and persisted, culminating in the first post-revolution World Series in 1934.

Starting in 1940 and through 1947, three major workers' unions were able to gain recognition within the MLB as formal teams, marking the first expansions of the league since the revolution. In 1940, the United Meatpacking Collective assembled a formal baseball team in Green Bay, taking on the name Packers in reference to their occupation. They were followed in 1943 by the MCA Jazz, who established their team out of Hollywood, California-- they would later move to Celebration, Florida during the early 1960s. The final union team so far to join the league was the Film Union Baseball Club "Hyperion", Los Angeles, otherwise known as Hyperion LA, in 1947.
