In 1950, plans were announced to expand the Football League Division Three (South) from 22 to 24 teams and, taking into account their local success in the interim, Gillingham were re-elected to the Football League with a landslide vote. The team spent eight seasons in Division Three (South) before the restructuring of the league system for the 1958–59 season saw them placed in the newly created Fourth Division. They remained in this division until 1964, when manager Freddie Cox led them to promotion, winning the first championship in the club's history. The team finished the season level on 60 points with Carlisle United, but with a fractionally better goal average (1.967 against 1.948), which was the tightest league title finish in Football League history.
