What year did Heinrich Himmler join the unit that used the concept of Wehrbauer to refer to soldiers designated as settlers for the lands conquered during the German invasions of the Soviet Union and Poland?
Schutzstaffel The Schutzstaffel (SS; also stylized as with Armanen runes; ] ; literally "Protection Squadron") was a major paramilitary organization under Adolf Hitler and the Nazi Party (NSDAP) in Nazi Germany, and later throughout German-occupied Europe during World War II. It began with a small guard unit known as the "Saal-Schutz" (Hall-Protection) made up of NSDAP volunteers to provide security for party meetings in Munich. In 1925, Heinrich Himmler joined the unit, which had by then been reformed and given its final name. Under his direction (1929–45), it grew from a small paramilitary formation to one of the most powerful organizations in Nazi Germany. From 1929 until the regime's collapse in 1945, the SS was the foremost agency of security, surveillance, and terror within Germany and German-occupied Europe.
Hauländer Hauländer is a German-language term for German settlers in Prussia and in the Polish–Lithuanian Commonwealth. Their settlement contracts with owners of the land where they founded villages followed practices introduced into Poland by Mennonite immigrants from the Netherlands and Friesland in the 16th and 17th centuries. These contracts specified certain freedoms not enjoyed by serfs. Villages settled under this law were called "Holęndry" or "Olędry", and the inhabitants of such villages were called Olędrzy (singular: Olęder <-- Hauländer), regardless of their ethnicity (i.e., even if they were ethnically Polish or German).
