blood and soil

noun1

1. •
   A nationalist, often fascist, ideology that sees genetic heritage (blood) and geographic territory (soil) as the most important values of a nation, typically associated with the idealisation of racial “purity”, reproductive fertility, agriculture and belligerence; examples include Nazism (cf. the concept of Lebensraum) and white nationalism in the United States.

   • Representatives of this line of thought around the world are, in many cases, echoing eco-fascist ideas that themselves are rooted in an earlier age of blood-and-soil nationalism. — 2021
