Which term refers to Austria's annexation by Germany in 1938?

• A. Anschluss
• B. Rhineland
• C. Sudetenland
• D. Isolationism

Answer: (A)

Anschluss is the term for Austria’s annexation by Germany in 1938. It describes the unification of Austria with Nazi Germany, driven by Hitler’s aim to bring all German-speaking peoples under one state. In March 1938 German troops entered Austria and the union was proclaimed, effectively ending Austria’s independence and expanding Germany’s territory. This action violated Austrian sovereignty and earlier post-World War I arrangements, and it set the stage for further German expansion later in the decade.

The other options refer to different events or ideas: the Rhineland relates to Germany’s 1936 remilitarization of a western border region, the Sudetenland is the area of Czechoslovakia annexed later in 1938, and isolationism is a policy choice about staying out of international conflicts rather than a territorial change.
