Blood and soil

Blood and Soil (translating the German   Blut und Boden) refers to the ideology focussing on a concept of ethnicity based on descent (Blood) and homeland (Soil). The German expression was coined in late 19th century Racialism and National Romanticism.

Richard Walther Darré popularized the phrase at the time of the rise of Nazi Germany (Neuadel aus Blut und Boden, 1930). Darré was an influential member of the Nazi party and a noted race theorist who assisted the party greatly in gaining support among common Germans.

The Reichserbhofgesetz of 1933 implements this ideology, stating that its aim is to
 * "preserve the farming community as blood-source of the German people" (Das Bauerntum als Blutquelle des deutschen Volkes erhalten)
