Want to understand German football passion? Watch the Revierderby. Borussia Dortmund against Schalke 04. They call it "the mother of all derbies" in Germany, and it's not just about geography.
Dortmund and Gelsenkirchen (Schalke's home) sit less than 20 miles apart in the Ruhr region. Both clubs emerged from working-class communities built on coal and steel. Both have fiercely loyal, football-obsessed supporters. There's no middle ground. Black-and-Yellow or Royal Blue. Pick a side.
How the rivalry developed
First Revierderby: 1924/25 season, Schalke won 4-2. Then came years of Schalke dominance. Between 1924 and 1942, Dortmund couldn't beat them in 18 attempts. Schalke won six German championships during that stretch.
1946/47 changed everything. Borussia Dortmund finally beat Schalke 3-2 in the Westfalenliga final. From then on, power shifted. Post-war Dortmund became the dominant force, though the rivalry's intensity never faded.
Revierderby moments that sound made up
The 1969 "Dog Bite Derby" is legendary. A police dog named Rex bit Schalke defender Friedel Rausch on his backside. He got a tetanus shot at halftime, finished the match, then received 500 Deutsche Marks and flowers as an apology.
In 1997, Schalke goalkeeper Jens Lehmann scored a 94th-minute equalizer from a corner. First keeper to score from open play in Bundesliga history. That same week, both clubs won European trophies - Schalke the UEFA Cup, Dortmund the Champions League. Franz Beckenbauer declared: "The heart of German football beats in the Ruhr."
Then there was 2017. Borussia Dortmund led 4-0 after 25 minutes. Schalke somehow mounted the most ridiculous comeback, equalizing in the 94th minute through a Naldo header. 4-4. Both sets of supporters looked completely drained. The Dortmund vs Schalke rivalry never disappoints.
Der Klassiker: Bayern and the big grudge
The Revierderby is about local pride. Borussia Dortmund against Bayern Munich - "Der Klassiker" - is something else. The bad blood comes partly from Bayern repeatedly signing Dortmund's best players. Mario Gotze, Robert Lewandowski, Mats Hummels - all made the switch to Munich.
The rivalry peaked in the 2013 Champions League final at Wembley. Bayern won 2-1 in an all-German showdown. Two different philosophies colliding: Bayern's financial muscle against Borussia Dortmund's organic growth model.
