Slav Outposts in Central European History [PDF ebook] 
The Wends, Sorbs and Kashubs

While many think of European history in terms of the major states that today make up the map of Europe, this approach tends to overlook submerged nations like the Wends, the westernmost Slavs who once inhabited the lands which later became East Germany and Western Poland. This book examines the decline and gradual erosion of the Wends from the time when they occupied all the land between the River Elbe and the River Vistula around 800 AD to the present, where they still survive in tiny enclaves south of Berlin (the Wends and Sorbs) and west of Danzig (the Kashubs).
Slav Outposts in Central European History – which also includes numerous images and maps – puts the story of the Wends, the Sorbs and the Kashubs in a wider European context in order to further sophisticate our understanding of how ethnic groups, societies, confessions and states have flourished or floundered in the region. It is an important book for all students and scholars of central European history and the history of European peoples and states more generally.
