Does Germany's defeat in WWII & expulsion of Germans from the East symbolize the end of the agrarian German mentality?

[Futurist]

I have recently bought these two books (written in Polish) about the Ostsiedlung:

- D. Leśniewska, "German Colonization and Colonization on the German Law in Medieval Bohemia & Moravia in the Light of Historiography"

Here are Tables of Contents in German (there is no English version unfortunately):

1) Piskorski's book:

Out of curiosity--what exactly are the best parts of each of these books, in your honest opinion?
