Lebensraum is a concept that states that a nation with a higher degree of development must conquer other nations with a lower degree of development, thus increasing its vital space.
This concept was widely used by Nazi Germany, who used it as a justification to dominate the territories of Eastern Europe. With this domination, the government of Germany believed that it could increase Germany's power and resources, and that it could colonize these territories by increasing the Aryan race.
