Liga II is the second tier league of the Romanian football league system. The league changed its name just before the start of the 2006-07 season, previously being called Divizia B.
Liga II has two parallel regional divisions, Seria I and Seria II, each with 12 teams. The clubs are divided based on a geographical criteria in order to avoid lengthy and expensive travels.
Generally, Seria I contains eastern teams while Seria II contains western sides, although clubs near the center of the country are allowed to choose in which series they will compete.
The first two teams in each series promote to the Liga I, while the last three in each series relegate to the Liga III.
Until the 2013-15 season Liga II had 2 groups of 16 teams each. At the end of the 2012-13 and 2013-14 seasons the last five teams were relegated.
