FC Salzburg

FC RB Salzburg was founded on 13 September 1933 as SV Austria Salzburg, after the merger of the city's two clubs, Hertha and Rapid. In 1950, the club was dissolved but re-founded later the same year. It reached the Austrian top flight in 1953, and finished 9th of 14 clubs in its first season there, avoiding relegation by five points.

Vienna-born Erich Probst was Salzburg's first-ever international, earning the last of his 19 Austrian caps on 27 March 1960. Adolf Macek, who made the first of his four international appearances on 9 October 1965, was the club's first local player to earn a cap for Austria.

Salzburg were top-flight runners-up for the first time in the 1970–71 season, gaining 43 points to Wacker Innsbruck's 44. The club's first-ever European campaign was in the 1971–72 UEFA Cup, and it was eliminated 5–4 on aggregate by Romanian club UTA despite a 3–1 home victory in the second leg. In 1974, Salzburg reached the Austrian Cup final for the first time, losing 2–1 away to Austria Wien in the first leg before a 1–1 home draw in the second.

In 1978, the club's name was changed to SV Casino Salzburg and in 1997, to SV Wüstenrot Salzburg, due to a sponsorship deal with an Austrian financial services corporation. The team often remained referred to as SV Austria Salzburg.

Salzburg reached their first and so far only European final, the 1994 UEFA Cup final, where they lost both legs 1–0 to Inter Milan. That same season, Salzburg won their first Bundesliga title, beating Austria Wien by 51 points to 49. The title was retained the following season as Salzburg beat Sturm Graz on goal difference. The 1995–96 season saw a drop to eighth place, one above a relegation play-off, but the club's third title in four seasons was won in 1997 as they beat holders Rapid Wien by three points.

Salzburg's inaugural UEFA Champions League campaign in 1994–95 saw them reach the group stage by beating Israel's Maccabi Haifa 5–2 on aggregate. They were drawn into Group D with holders and eventual finalists Milan and eventual winners Ajax, as well as AEK Athens. Despite drawing both matches with Ajax, Salzburg picked up a solitary 3–1 win away in Athens and were eliminated in third place.

The club moved to its current stadium in 2003.

The Red Bull company headed by Dietrich Mateschitz purchased the Salzburg Sport AG on 6 April 2005. The club's bylaws were amended so that the Red Bull Salzburg GmbH has the sole right to appoint and recall board members of the club. After the takeover, Mateschitz changed the club's name, management, and staff, declaring "this is a new club with no history". The club's website initially claimed that it was founded in 2005, but was ordered to remove this claim by the Austrian Football Association. The new authority removed all trace of violet from the club logo and the team now play in the colours of red and white, to the consternation of much of the club's traditional support. A small pair of wings form the motif of the new club crest, displayed on the team jersey, in accordance with Red Bull's commercial slogan at the time: "gives you wings". This complete re-branding of the team proved very similar to Red Bull's treatment of its two Formula One racing teams, Red Bull Racing and Scuderia Toro Rosso, now rebranded as RB Formula One Team. Red Bull, however, would not completely follow this precedent when it acquired the MetroStars club in Major League Soccer (MLS) in the United States; while it rebranded the team as the New York Red Bulls, it chose to recognise the MetroStars' history.

The traditional supporters tried to resist the radical changes and formed their own movement in order to regain some of the tradition. Several fan-clubs throughout Europe voiced their support in what they saw as a fight against the growing commercialisation of football. However, after five months of protests and talks between the club owners and traditional fans, no compromise was reached. On 15 September 2005, the "violet" supporters stated that the talks had irreversibly broken down and efforts to reach an agreement would be terminated.

This gave rise to two separate fan groups: the "Red-Whites", who support "Red Bull Salzburg" and the "Violet-Whites", who want to preserve the 72-year-old tradition and refuse to support the rebranded club. The Violet-Whites ultimately formed a new club, Austria Salzburg after viewing Red Bull's offer to maintain the original colours only for the goalkeeper's socks at away games as an insult.

The club's history going back to 1933 was later restored on the club website.

In May 2006, Red Bull announced on their website that they had hired veteran Italian coach Giovanni Trapattoni, together with his former player, German FIFA World Cup winner Lothar Matthäus, as co-trainers. The pair initially denied having reached a deal, but officially signed on 23 May 2006. On 28 April 2007, Red Bull ultimately won the 2006–07 Bundesliga by a comfortable margin with five games still left in the season after drawing 2–2 with previous season's champions Austria Wien.

Red Bull were beaten by Shakhtar Donetsk in the third qualifying round of the 2007–08 UEFA Champions League, and were then knocked out of the 2007–08 UEFA Cup in the first round by AEK Athens. On 13 February 2008, Giovanni Trapattoni confirmed that he would be taking over as the new Republic of Ireland national team manager in May. In his final season, the club finished as runners-up, six points behind champions Rapid Wien. Trapattoni was succeeded by Co Adriaanse, under whom they finished as champions, but he left after one year. His successor was Huub Stevens. On 14 May 2010, Stevens' Red Bull retained the Bundesliga.

Stevens was replaced by Dutchman Ricardo Moniz at the end of the 2010–11 season, in which Red Bull were denied a third consecutive title by Sturm Graz, who won the league by a three-point margin. Red Bull finished second in the league, and qualified for the following season's UEFA Europa League. Moniz was ordered to integrate young players from the Junior squad: at the beginning of the 2011–12 season Daniel Offenbacher, Martin Hinteregger, Georg Teigl and Marco Meilinger were promoted to the first team. In the 2011–12 season, Red Bull won the Bundesliga league title and Cup double.

After the 2011–12 season, Moniz departed his post despite having a year remaining on his contract. The new coach for the 2012–13 season was Roger Schmidt, who came from SC Paderborn of the German 2. Bundesliga. In July 2012, Red Bull were knocked out of the Champions League in the second qualifying round against F91 Dudelange of Luxembourg, losing the first leg 1–0 away, followed by a 4–3 home win which saw the club eliminated on away goals.

After that, the team was changed fundamentally. At the end of the transfer period, new players were purchased: Valon Berisha, Kevin Kampl, Håvard Nielsen, Sadio Mané, Isaac Vorsah, and Rodnei. In the 2012–13 season, the team finished second in the league, behind champions Austria Wien. They recaptured the league title the following season with an 11-point margin over the runners-up. Also, in the 2014–15 season, they won both the Bundesliga and the cup as they did again in the 2015–16 season. In December 2014, the coach Peter Zeidler was dismissed and replaced for the last two matches in the first half of the season by Thomas Letsch. Then Óscar García took over.

Also in the next 2016–17 season, Salzburg won both the Bundesliga and the cup. In 2018, Salzburg lost the cup final against Sturm Graz. At the beginning of the 2017–18 season, Marco Rose became coach after Óscar García left the club. In the UEFA Europa League, Salzburg reached the semi-finals in which they lost to Olympique de Marseille 2–3 on aggregate after extra time, having won during the campaign against Borussia Dortmund and Lazio.

After eleven failed attempts to reach the group stage, Red Bull only managed to qualify directly to the 2019–20 Champions League, since the 2018–19 UEFA Champions League winner, Liverpool, qualified to the competition via their domestic league.

In the years from 2013 to 2019, Salzburg earned €300 million from transfers of players like Mu'nas Dabbur, Xaver Schlager, Stefan Lainer, Hannes Wolf, Diadie Samassékou, Takumi Minamino, Sadio Mané and Erling Haaland, all while earning a reputation for finding and developing promising young talent.

In 2021, Salzburg had a transfer balance of €218 million for the last five seasons, behind UEFA Champions League participants Ajax (€242 million) and Benfica (more than €335 million). Salzburg had a positive balance in every year. In the 2020–21 and 2021–22 seasons, they reached both the Championship and the Cup finals. In the 2021–22 UEFA Champions League, they reached the knock-out stage for the first time. In the round of 16, they played versus Bayern Munich.

On 17 April 2024, Salzburg qualified for the 2025 FIFA Club World Cup in the United States following Arsenal's elimination from the 2023–24 UEFA Champions League.
