In 1915 the Federal League filed a lawsuit to prevent Major League Baseball from barring them from becoming a third major league. Kenesaw Mountain Landis was the judge in that case. He famously let litigation drag on until the Federal League went bankrupt. This league juxtaposes he was not the judge on the case and the Feds won their lawsuit, thus making three major leagues.
The Feds, finally finding stability, played the next 5 seasons with only one major change: for the 1920 season, citing travel costs, the league split into a two division format. The winners of the division would compete for the league title in a best of 7 series.
