Italy, the United Kingdom, France, and Germany signed the Four-Power Pact—an attempt to coordinate great-power diplomacy within the League of Nations framework. Although it proved of limited practical effect, it reflected early efforts to manage (and in some cases accommodate) German revisionism after Hitler’s rise.
Germany announced its withdrawal from both the League of Nations and the World Disarmament Conference, signaling a decisive break with interwar collective-security and disarmament efforts and foreshadowing unilateral rearmament.
Germany and Poland signed a 10-year non-aggression declaration, temporarily normalizing relations and undermining aspects of France’s Eastern European security posture while Germany continued to revise the Versailles order elsewhere.
In the Saar plebiscite, voters overwhelmingly chose reunification with Germany. The outcome removed a post–World War I League of Nations mandate arrangement and provided Hitler’s regime a diplomatic/propaganda success through a formally legal process.
Germany announced immediate general military conscription and openly repudiated key military restrictions of the Treaty of Versailles, accelerating rearmament and heightening tensions with neighboring states.
Britain, France, and Italy agreed at Stresa to oppose further unilateral treaty changes by Germany and to reaffirm support for Austrian independence. The front soon weakened, illustrating the fragility of anti-German diplomatic alignment in the mid-1930s.
France and the Soviet Union concluded a mutual assistance pact intended to deter German aggression. German leaders later cited the treaty as part of their justification for subsequent moves (notably in the Rhineland).
Britain and Germany signed a bilateral naval limitation agreement allowing German naval expansion up to 35% of British tonnage, effectively permitting Germany to exceed Versailles limits and straining Allied unity over how to respond to German rearmament.
After the required notice period, Germany’s withdrawal from the League of Nations took full effect, removing one of the remaining formal ties to interwar collective-security institutions.
German forces entered the demilitarized Rhineland in violation of the Treaty of Versailles and the Locarno Treaties. The lack of a military response from France and Britain strengthened Hitler’s confidence in further risk-taking diplomacy and expansion.
Germany and Italy reached an agreement informally linking the two fascist states, a key step toward the Axis alignment that reshaped European diplomacy and reduced Italy’s incentives to oppose German expansion.
Germany and Japan signed the Anti-Comintern Pact, publicly aimed against the Communist International but also signaling a broader geopolitical alignment that would later expand with additional adherents.
At a high-level meeting recorded in the Hossbach Memorandum, Hitler discussed strategic aims and timing for territorial expansion—often treated by historians as an important window into Nazi planning before the crises of 1938–1939.
German forces entered Austria and annexed it into the Reich, eliminating Austrian independence and shifting the Central European balance of power while demonstrating the limited effectiveness of diplomatic opposition.
Germany, Britain, France, and Italy concluded the Munich Agreement, permitting German annexation of the Sudetenland. The settlement epitomized appeasement and critically weakened Czechoslovakia’s strategic position.
Germany and Italy arbitrated the First Vienna Award, compelling Czechoslovakia to cede territories to Hungary. The decision further dismantled Czechoslovakia after Munich and increased German leverage in the region.
German troops entered Bohemia and Moravia, ending the remaining Czech state’s independence. This move went beyond the Munich framework and helped convince Britain and France that Hitler’s aims were not limited to ethnic German claims.
Hitler proclaimed the Protectorate of Bohemia and Moravia, formalizing German control over the Czech lands and integrating their strategic industrial and economic resources into the Reich.
Germany and the Soviet Union signed a major trade/credit arrangement that helped underpin the rapid political rapprochement culminating in the Nazi–Soviet non-aggression pact days later.
Germany and the Soviet Union signed a non-aggression pact that included a secret protocol dividing Eastern Europe into spheres of influence—removing a major strategic obstacle to Germany’s move against Poland.
Germany launched its attack on Poland, a decisive escalation that triggered British and French declarations of war and marked the start of World War II in Europe.
