Since the 1950s, Gaisfc has been a team that often moved back and forth between the Allsvenskan and lower series. After winning the Allsvenskan in 1954, the team ended up in third last place in 1955, which meant relegation. The rule that three teams were relegated only applied for two seasons, 1953/1954 and 1954/1955. Then they returned to the rule with two relegated teams.
In 1963, Gai won the qualifier and was thus back in the Allsvenskan in 1964, but left again despite the fact that coach Gunnar Gren went in and played during the autumn. In 1965, Gais returned to the Allsvenskan and secured his promotion after a victory against Grimsås IF. Among the profiles in Gais fc in the 1960s were Jan Olsson and Kurt Axelsson who became both national team players and foreign professionals. In 1969, four gaisers played in the national team when Hasse Johansson and Sten Pålsson were also taken out by the national team captain Orvar Bergmark. In 1970, Eine Fredriksson was recruited as an advanced national team player.
The game in lower divisions has been interspersed with some higher Allsvenskan placements, such as a fourth place in 1974. In the late 1970s, Gaisfc had major problems with the economy.
During the derby between Gais Football and IFK Gothenburg on May 20, 1976, 50,690 spectators came to Ullevi, which was an audience record for the then Division II, corresponding to today’s Superettan.
In the game year 1980, Gais fc was on his way up in the Allsvenskan, but was passed by Örgryte in the final battle. The following year, the team finished last in the then Division II.
In the 1982-1983 season, Gais played in the third division.
GAIS, which was in the then Division II South, recruited Samir Bakaou in the spring of 1984. In 1985, Bakaou played in midfield with defensive player Lenna Kreivi and had a good collaboration with top forwards Ulf Köhl and Steve Gardner; together they were called “the golden triangle”. Bakaou won the shooting league in the southern second with 20 goals and was named the best player in the series. Gais qualified for the Allsvenskan against Djurgården, but fell on penalties after two draws.
Under coach Bo Falk, Gaisfc, with a game system characterized by long balls, achieved success in the late 1980s. The big profile was Samir Bakaou. In 1988, Gaisfc joined the Allsvenskan again. Gais eventually finished eighth in the series and stayed. Bakaou scored ten goals and became the team’s top scorer.
In 1989, Gais fought for a medal in the Allsvenskan. The team lost the semifinal against Malmö FF, but took a place in the UEFA Cup 1990/1991.
After Gais left the Allsvenskan in 1992, Bosse Falk became club director of Gais in 1993. He returned as Gais coach for a short stay in 1996 to try to save Gais in the then division I south.
Gais fc played 1997-1998 in Division II.
