Blood and Soil (German: Blut und Boden) refers to the ideology focusing on a concept of ethnicity based on descent (Blood) and homeland (Soil). It celebrates the relationship of a people to the land that they occupy and cultivate, and places high esteem on the virtues of rural (as opposed to urban) living. 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; he wrote a book called Neuadel aus Blut und Boden in 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 outside the cities.
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).
