However, many nation states accept specific minorities as being part of the nation, and the term "national minority" is often used in this sense. The Sorbs in Germany is an example: for centuries they have lived in German-speaking states, surrounded by a much larger ethnic German population, and they have no other historical territory. They are now generally considered to be part of the German nation and are accepted as such by the Federal Republic of Germany, which constitutionally guarantees their cultural rights. Of the thousands of ethnic and cultural minorities in nation states across the world, only a few have this level of acceptance and protection.
