Liga IV is the fourth level of the Romanian football league system and is run in all 41 counties and in the Municipality of Bucharest.
In the beginning, matches were played in a cup-style system, with participating teams primarily coming from the Muntenia region, especially from Bucharest and Ploiești.
Starting with the 1921–22 season, the Football Association Commission decided to modify the competition's structure, introducing a new system: the winners of each district championship across the country would qualify for the national phase to determine the Romanian champion.
Thus, Romanian football was divided into five geographical leagues – North, West, South, East, and Center, each subdivided into districts.
The winning team would then earn the right to participate in the national phase's final tournament, where it would compete for the title of Romanian champion.
