[7] They reached the final again in 1918, but with two of their best players missing due to falling ill with the Spanish flu, they again lost to an eastern team, this time Kvik Fredrikshald.

The year also marked the first time a Brann player received an international call-up, with Sigurd Wathne playing in goal for Norway in games against Sweden and Denmark.

The 1959–60 season saw the debut of 17-year-old future club legend Roald "Kniksen" Jensen, but Brann were nonetheless relegated for a fourth time and were as usual immediately promoted.

Brann defended their title in the first regular season of single-division top flight football in 1963, adding a second league trophy to their cabinet.

Silver and bronze medals are sometimes received with a shrug, but Brann's dismal league history made them a top priority for the club in the 1990s.

In 1990, Brann were involved in a decisive match against Rosenborg in the final round where they had the chance to clinch the league title, but lost and ended fourth.

[14] In 1991, after a shock resignation of manager Teitur Thordarson, Brann once again struggled, and needed a win in their last game against Strømsgodset in order make the play-off spots against two second-tier teams and avoid direct relegation.

His extremely dedicated style, his innocent and somewhat naïve personality and the fact that many of his goals were scored as a midfielder made him immensely popular.

With Brann at bottom position halfway through the league season, Thoresen was sacked and Kjell Tennfjord, the manager behind Fyllingen's success, was appointed.

In 1996, as in 1990, Brann were denied bronze medals in injury time of the last game, after a terrible blunder by keeper Birkir Kristinsson.

In their impatient but unfruitful struggle to reclaim the glory of the 1960s, Brann over the years gained a reputation for inept leadership, unfounded enthusiasm or optimism and almost continuous internal unrest, deservedly or not.

After former Brann player Mons Ivar Mjelde took over as manager in 2003, however, this image changed, as the leadership embraced continuity and down-to-earth principles.

Nonetheless, Brann opened the season strongly with victories over reigning league champion Rosenborg and Lillestrøm in the first and second rounds.

[25] Although the season did not continue quite as strongly, Brann remained a contender for a top three position in the league and the team also qualified for its 15th cup final.

[27] The season was also marred by Brann player Carl-Erik Torp suffering a cardiac arrest on the pitch against Sogndal, only narrowly surviving and having to retire from professional football afterwards.

This result meant that Mjøndalen were promoted at the expense of Brann who were relegated, ending the longest top tier streak in the club's history.

[28] Norling still had support amongst fans, with the blame mostly being put on decisions made by the club leadership and board, who resigned after the relegation was confirmed.

The following season the team continued to struggle, and in the end Norling was sacked on 27 May 2015[29][30] after a 4–1 loss against Levanger left Brann 9th in the table and 9 points behind league leader Sogndal.

Although he had given Brann initially good results, attendance figures had steadily dropped under Nilsen's tenure as manager in large part due to his style of football being considered boring, risk-averse and frustrating to watch.

[36] After a loss to rivals Vålerenga in round 12 saw Brann in 8th with no wins in 5 games, Nilsen departed from the club and was replaced by Kåre Ingebrigtsen, who recently had great success with Rosenborg.

[37] It included a controversial extraordinary general meeting, a season-long relegation struggle, the departure from the club of a sporting director, a manager and a squad-wide afterparty scandal.

[38] The 2021 season was marked with controversy even in the pre-season, when the board of the club decided to replace the stadium's natural pitch with artificial turf to great uproar among Brann supporters.

After a heated discussion the members rejected the board's plans to install artificial turf by 130 votes to 107, ensuring Brann would keep its grass pitch.

In the week leading up to the vital first game after the summer break a social gathering and dinner was held to introduce the many new signings to the squad.

The same day the veteran Brann player Kristoffer Barmen was sacked, the club accusing him of having played a central role in organizing the activities.

Meanwhile, Odd comfortably beat Stabæk 3–1, meaning Brann had miraculously secured a relegation play-off from what looked like certain doom.

Due to the COVID restrictions the usual two-leg structure of the play-offs was abandoned in favor of a single game played on neutral ground at Intility Arena in Oslo.

On the day of the match the stadium was enveloped in a thick fog, severely reducing visibility for both players, spectators and people watching on television.

Brann challenged Bodø/Glimt for the top spot for parts of the season, but after a poor run of form in July they had to struggle against Viking and Tromsø for the silver medal, which they eventually won.

Brann qualified for the delayed 2022 cup final, where they comfortably beat Lillestrøm 2–0, earning the club its first major trophy on the men's side since 2007.
