I want to know the answer to the following question:
What leader tried to unite all people considered themselves "German"
All the background I'm provided with is that "The Nazis, led by Adolf Hitler, attempted to unite all the people they claimed were "Germans" (Volksdeutsche) into one realm, including ethnic Germans in eastern Europe, many of whom had emigrated more than one hundred fifty years before and developed separate cultures in their new lands.". Is that enough to answer the question?
Answer: yes
