On 7 March 1936, Adolf Hitler flagrantly violated the Treaty of Versailles and the Locarno Pact by ordering German troops into the Rhineland, a demilitarised zone since the end of World War I.
This audacious move, executed with calculated risk, tested the resolve of Britain and France, both of whom refrained from military intervention despite the clear breach of international agreements.
Emboldened by the lack of resistance, Hitler's confidence soared, setting a dangerous precedent that would pave the way for further expansionist aggression, ultimately hurtling Europe toward the cataclysm of World War II.
