History
The Corps Borussia Bonn was established on 22 December 1821 at the University of Bonn in Bonn, Germany. It is the corps of the House of Hohenzollern and Prussian nobility.
The Corps Borussia Bonn joined the Kösener Senioren-Convents-Verband (KSCV) in 1856. In 1864 and 1883, Borussia headed the KSCV. In 1933, the KSCV amended its bylaws to require member corps to expel anyone of Jewish ancestry or with a Jewish spouse, a rule that affected twelve Borussia members. Rather than formally expel them, the corps initially attempted to persuade the affected members to resign voluntarily. The matter came to a head at a members' meeting on 13 October 1935, when Paul Graf Yorck von Wartenburg protested the policy and announced his resignation; the corps voted to dissolve itself at that same meeting rather than comply with the expulsion requirement.
The Corps Borussia Bonn reestablished itself in 1949, after the defeat of the Nazis in World War II. Corps records indicate the reestablished corps was active by the mid-1950s: the Wiener Holocaust Library in London holds correspondence and Corps Borussia semester reports dated 1954–1962 relating to a lecture Alfred Wiener gave to the corps.
The corps' alumni organization, the Verein der Alten Herren des Corps Borussia Bonn e.V. ("Association of Old Members"), remains currently registered in the German register of associations (Vereinsregister) at the District Court of Bonn (VR 2182) as of 2026.
