Which region was designated a demilitarized zone by the Treaty of Versailles and later remilitarized by Hitler in 1936?

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

Answer: (B)

Rhineland. After World War I, the Treaty of Versailles made that region a demilitarized zone to act as a buffer against France. In 1936, Hitler violated the treaty by sending German troops into the Rhineland and rearming the area, a bold step that undermined the postwar settlement and encouraged further aggression. The other options don’t fit: the Sudetenland is a part of Czechoslovakia connected to later annexation efforts, not a demilitarized zone; the Holocaust refers to genocide, not a place; isolationism is a policy stance, not a region.
