The league changed its name from Divizia B just before the start of the 2006–07 football season.

[1] Since its inception in 1934, Liga II has had between 2 and 9 parallel divisions, with clubs divided based on geographic regions.

But since the 2016-17 Liga II, it changed to one group of 20 teams.

On 14 July 2023, the federation announced that the league will be expanded to 22 teams starting with the 2024-2025 season.

The new format will be similar to the current one, with teams playing each other once in the regular season ( for a total of 21 match days this time ), followed by a promotion play-off with 6 teams, playing each other twice, and a relegation play-out with two groups of 8 teams playing each other once ( as opposed to the current play-out format with groups of 7 also playing each other once ).
