​​The Black Brigade were the Flemish that collaborated with the Nazi Occupiers. It consisted of the VNV (Vlaamsch Nationaal Verbond, a Flemish nationalist political party in Belgium from 1933 to 1945) and the Verdinaso (Verbond van Dietsche Nationaal-Solidaristen or Union of Dutch National Solidarists, a Belgian fascist political movement active between 1931 and 1941).

​The house located here was named the “Vlaamsch Huis” (Flemish House). From here, riots broke out on the Market Square on 21 July 1941 after a spontaneous parade was held on Belgian National Day.

​After the liberation, the house came into the hands of veterans from World War I and World War II, who renamed it the “Strijdershuis” (Veteran's House). Today it still has this name.
