 By 1921, an Alumni Board ("," lit., "Philistine outshoot") was elected after much debate within the "Kartellverband", the individual "Studentenvereine" having established alumni's unions ("Philistervereine") from 1913; the principle of federal life governed the Board.From 1930, membership declined as a consequence of the economic crisis that started with the mass stock sell-off at the New York Stock Exchange on October 29, 1929.The "Kartellverband" faced a triple whammy that eventually resulted in forcible decorporation on July 6, 1938 under the "Verbot der Korporationsverbände"
