These parts of eastern Germania are sometimes called Germania Slavica in modern historiography.

West Slavic tribes ("Wends") had settled in the Germania Slavica region from the 7th century onwards.

Historian Klaus Zernack divides Germania Slavica into:

( See Germania magna , Germania Slavica)

From the late first millennium CE, Slavic tribes (collectively referred to as Wends) settled in Germania Slavica.

Germania Slavica, a historiographic term used since the 1950s, denotes the medieval contact zone between Germans and Slavs in East Central Europe.

While the Wends were arriving in so-called Germania Slavica as large homogeneous groups, they soon divided into a variety of small tribes, with large strips of woodland separating one tribal settlement area from another.

The historic description Windisch was applied in the German-speaking area to all Slavic languages (confer Wends in Germania Slavica) and in particular to the Slovene language southern Austria until the 19th century.

The word Kietz originated in the time of the eastward expansion of German settlers in the Middle Ages into West Slavic territories (Germania Slavica), when in many places both communities existed side by side.

At the time when the 500-year-long Ostsiedlung process was stopped by the Black Death in the mid-14th century, Germans had settled the "Wendish" Central European areas of Germania Slavica far beyond the Elbe and Saale rivers.

Germania Slavica II east of Germania Slavica I and west of the Kingdom of Poland, comprising the Silesian, Pomeranian, and Prussian duchies as well as the Neumark.

Derived from the name Wends (Wenden) for Western Slavs settling in the Germania Slavica contact zone, the medieval German term windisch referred to the Slovene language; not to be confused with Wendische, the historic German term for the Sorbian-speaking population in Lusatia.
