After German reunification in 1990, Jena entered the 2. Bundesliga. Their second-place finish in 1992 deteriorated into a 17th-place finish in 1994 and relegation to Regionalliga Nordost (III). They won immediate promotion, and played for three more years at tier-II level. Since 1999 the team has primarily played tier III and IV football, but a second place-finish in the Regionalliga Nord secured Jena promotion to the 2. Bundesliga for the 2006–07 season. Jena remained in the 2. Bundesliga by winning 2–1 away against FC Augsburg in their final match of the season. They finished last in the 2. Bundesliga in 2007–08, returning to the third tier. However, this would not be one of the Regionalligen; the German Football Association (DFB) launched the new 3. Liga for 2008–09, of which Jena was a charter member.
