[citation needed] After its foundation, Hamburger SV rose to become the largest club in the city, and after the Second World War, FC St. Pauli replaced Eimsbütteler TV as a competitor of "HSV".

[citation needed] The first win for FC St. Pauli, whose nickname is "Kiezkicker", came on 19 October 1930, when they won 1–0 in their first encounter in the "Oberliga Hamburg".

[citation needed] The return match was also played in the Hamburger SV stadium, although FC St. Pauli was the home team.

[citation needed] The next clash occurred in the 1986/87 season, when Hamburger SV played FC St. Pauli in the DFB Cup.

[citation needed] To the end of the 2021–22 season, FC St. Pauli missed the promotion to Bundesliga and placed fifth; Hamburger SV placed third and qualified for the promotion/relegation play-offs against Hertha Berlin.

[citation needed] The political divide was particularly notable in the 1980s, when the HSV fan scene had a small contingent of organized neo-nazi groups.

[citation needed] St Pauli's supporter base is more left-wing due to its popularity among squatters and counterculture subcultures of the local area in the 80s, specifically when squatters from the Hafenstrasse and Rote Flora started attending St. Pauli matches and created the leftist fan scene the club is known for today.

[citation needed] Additionally, over time HSV has developed a more inclusive fanbase, such as signing a refugee player[3][failed verification] and having a first team coach of color.

Subsequently, St. Pauli fans attacked their rivals' choreography preparations, injuring two HSV ultras in the process.
