The Early Era and the Birth of the Modern World Series
The inception of the World Series in 1903 between the National League and American League champions established the formal mechanism for crowning an MLB champion, although the "champions by year" list for the preceding decades includes the champions of each individual league. The early years were defined by the powerful pitching of the Chicago Cubs and the defensive mastery of the New York Giants, setting a tone of gritty competition. It wasn't until the Babe Ruth era began in the 1920s that power hitting transformed the game, with the New York Yankees rising to prominence and establishing a dynasty that would define the sport for a generation. This period cemented the World Series as the ultimate prize, a stage where legends were made and the identity of the best team in baseball was settled once and for all.
