Der Kampf um den Rhein 1932-36

German Reoccupation of the Rhineland (1936):
This was a pivotal moment when German troops re-entered the demilitarized zone, defying the Treaty of Versailles and the Locarno Pact.

Diplomatic Fallout:
The film likely touches on the international response, especially from France and Britain, and how their reluctance to intervene emboldened Germany.

Nationalist Symbolism:
Expect strong visual and rhetorical emphasis on the Rhine as a symbol of German pride and sovereignty.
