"Blood and Soil" is a nationalist ideology that emphasizes the connection between a specific ethnic group and their homeland. It suggests that a people's identity is deeply rooted in their ancestry and the land they inhabit. This concept has been used to promote ideas of racial purity and territorial integrity, often leading to exclusionary or xenophobic policies. Historically, the phrase gained prominence in the early 20th century, particularly in Nazi Germany, where it was used to justify expansionist policies and the persecution of those deemed outsiders. The ideology has since been associated with various far-right movements around the world, advocating for the preservation of a perceived cultural and ethnic homogeneity.
