Bevara Sverige Svenskt (BSS, "Keep Sweden Swedish") was a Swedish racist movement based in Stockholm and is a slogan used by various Swedish nationalist parties. The stated objective of the BSS movement, and the aim of the slogan, was to initiate a debate in order to stop immigration by non-Europeans and repatriate non-ethnic Swedes. Inspiration came from the post-WW2 nazi organisation Nysvenska Rörelsen created by Per Engdahl.
Founded as a loosely coupled network in 1979 by Leif Zeilon, and formalized as an organization in 1983, BSS was involved with the populist Progress Party (Swedish: Framstegspartiet) in 1986. This co-operation took place under the name Sweden Party (Swedish: Sverigepartiet). This cooperation evolved into the Sweden Democrats (Swedish: Sverigedemokraterna) (SD) in 1988.
Claiming not to be racists, their often aggressive sticker campaigns arguably spoke a different language with slogans such as "Låt inte din dotter bli en negerleksak" (Don't let your daughter become a negro toy) and "Negrer hotar sina offer" (Negros threaten their victims).
Although the number of members was comparatively small, BSS represented the first organized attempt to reduce immigration and as a result received massive media attention.
The slogan "Keep Sweden Swedish" was taken on by the Sweden Democrats and became prevalent during 2003-2004, when it was used for headlines in the party newspaper "SD Kuriren" and as slogans on bumper stickers.
