Red Bull Salzburg

1933–1953, founding, promotion to A-league

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.

1953–1970

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.

1970–1990

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 Arad 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.

1990–2010

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, the Red Bull Arena in 2003.

The Red Bull takeover

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.

Traditional supporters sought to resist the radical changes by forming their own movement in an effort to preserve aspects of the club’s heritage. Several fan clubs across Europe expressed support, viewing the dispute as part of a broader struggle against the increasing commercialisation of football.

However, after five months of protests and negotiations between club owners and traditional fans, no compromise was reached. On 15 September 2005, the “violet” supporters announced that talks had irreversibly broken down and that efforts to reach an agreement would be discontinued.

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.

Red Bull era

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.
