The Sorbs (a linguistic community from the Slav language group, living in Eastern Germany) were an overprotected minority during the time when the German Democratic Republic was part of the Warsaw pact, which consisted of a vast majority of Slav languages speaking countries. Since the reunification of Germany they have maintained their position. During GDR-times (1948-1990) topographic maps at scales 1:25 000 and larger of areas with linguistic minorities had to be bilingual. See for example the town plan of Bautzen (German) or Budyšin (Sorbian), which also had a bilingual legend.

Current German map 1±1 million with bilingual place names for the Sorbian minority area.
