The DRKB, "Deutscher Reichs-Krieger-Bund" (German National-veterans’-association), was formed during WWI, and based on the DKB, "Deutscher Krieger-Bund," originally formed in the 1870s. By 1936 it had incorporated most of the varied veterans’ associations into it, and was itself re-named the NS-RKB, "Nationalsozialistische Reichskriegerbund" (National-socialist State-veterans’-organization), in 1938.
