The 1930s saw the rise of the Third Reich, which restructured sports and football organisations throughout the nation to suit the regime's goals. Borussia's president was replaced when he refused to join the Nazi Party, and a couple of members who surreptitiously used the club's offices to produce anti-Nazi pamphlets were executed in the last days of the war. The club did have greater success in the newly established Gauliga Westfalen, but would have to wait until after World War II to make a breakthrough. It was during this time that Borussia developed its intense rivalry with Schalke 04 of suburban Gelsenkirchen, the most successful side of the era (see Revierderby). Like every other organisation in Germany, Borussia was dissolved by the Allied occupation authorities after the war in an attempt to distance the country's institutions from its so-recent Nazi past. There was a short-lived attempt to merge the club with two others – Werksportgemeinschaft Hoesch and Freier Sportverein 98 – as Sportgemeinschaft Borussia von 1898, but it was as Ballspiel-Verein Borussia (BVB) that they made their first appearance in the national league final in 1949, where they lost 2–3 to VfR Mannheim.
