The Third Division South had been formed the previous season (as simply the Third Division) with 22 teams mostly from the Southern League. It was decided that this gave the league too much of a southern bias, so the Third Division North was created to redress the balance. However, there was not a northern equivalent of the Southern League, so only 20 teams could be found, taken from several regional leagues: the Midland League, the Central League, the North Eastern League, the Lancashire Combination and the Birmingham Combination. A further two teams were added in 1923 to take the total to 22.
Only one promotion place was available each season from Third Division North to the Second Division, which made it very difficult to win promotion. Eight teams were ever-present in the division for the thirty years of its existence.
The Football LeagueThirdDivision South was a level of English professional football which ran in parallel to ThirdDivisionNorth from 1921 to 1958.
The division was created in 1921 from the ThirdDivision, formed one year earlier when the Football League absorbed the entire top division of the Southern League, effectively ending the ambitions of that league to rival the Football League.
In 1958, the North and South sections were merged together, to form a single ThirdDivision and a new Fourth Division.
