What do you mean by LEBENSRAUM? 

Answer: Lebensraum means Living Space. This geopolitical concept was given by Hitler to annex neighbouring territories.

He believed that new territories had to be acquired for settlement which would enhance the area of mother country and

enable the settlers on new lands to retain an intimate link with the place of origin. 

It would also enhance the material resources and power of the German nation. Poland was acquired based on this idea.
