World War II: Causes, Consequences, and Impact
1. Causes of World War II
a) Totalitarian Regimes
* Italy and Germany sought to expand their territories and challenged the status quo established by the League of Nations. * They strengthened their armies and encouraged militarism. * These countries experienced growing nationalism and adopted aggressive foreign policies.
b) Escalating Aggression
* In the 1930s, authoritarian states launched a series of hostile attacks. * In Africa, Italy invaded Ethiopia and Albania. * Italy and Germany supported the insurgent forces in the Spanish Civil War, while France and Great Britain remained neutral. * In 1936, Hitler remilitarized the Rhineland, violating the Treaty of Versailles. * In March 1938, Germany occupied Austria and demanded Czechoslovakia, which had a significant German minority.
2. The Course of the War
a) Axis Victories (1939-41)
* Following the invasion of Poland, Hitler launched Blitzkrieg, a lightning war using armored divisions and strong aerial support. * Poland collapsed in three weeks and was divided between Germany and the USSR. * In 1940, Germany invaded most of Western Europe. * Germany bombed British ports and cities, but Great Britain resisted the attacks. * Hitler ordered the blockade of Britain to isolate them and cut off their supplies. * Yugoslavia and Greece also fell in 1941. * In June 1941, Hitler launched Operation Barbarossa and attacked the USSR. * In December, Japan attacked Pearl Harbor, bringing the US into the war.
b) Allied Offensives
* The Americans stopped Japanese advances in the Pacific (Battles of Midway and Guadalcanal) and began reconquering occupied territories. * In North Africa, the British defeated the Germans at El Alamein. * The German assault on Stalingrad was Hitler’s first major failure. The city resisted months of attack before the German Field Marshal surrendered. * After this, the Soviets went on the attack. * The liberation of Europe was accelerated by British and American troops, who brought in many soldiers and weapons. * They defeated German resistance and began advancing from the west, liberating parts of France and entering Germany. * At the same time, Russia pushed the Germans out of Poland. * To support these advances, German cities were bombarded. * Both Allied forces occupied Germany and met at the River Elbe. * Hitler committed suicide on April 30, and on May 8, Germany surrendered.
3. Consequences of the War
a) Human and Material Losses
* Over 50 million people died in the war, with the largest proportion from the USSR, followed by Germany and Poland. * The weapons, bombs, and airplanes used during the war increased the capacity for destruction. * Civilian casualties were higher than military casualties. * There were also population displacements and extensive damage to major cities.
b) Moral Impact
* Human rights had been violated, and a culture of evidence had become established. * The Nazis committed atrocities in concentration camps and exterminated Jews. * The atomic bombs dropped on Japan were interpreted as a global apocalypse.
c) From Peace Conferences to Confrontation
* The three Allied leaders met for the first time at the Tehran Conference in 1943 (Churchill, Roosevelt, and Stalin). * The second conference took place in Yalta in 1945, leading to the division of Germany and Austria into four occupied zones and the division of Berlin and Vienna. * The third peace conference was held in Potsdam in 1945 (Attlee, Truman, and Stalin), returning all European territories annexed by Germany, separating Austria, and dismantling military industry. * Peace treaties with Germany were signed at the Paris Peace Conference in 1946.
4. Fascism and Nazism
a) Fascism in Italy
* Causes: Dissatisfaction with the peace agreements after World War I, economic crisis, unemployment, and inflation. * Fascism was created by Benito Mussolini, who used paramilitary groups to suppress the workers’ movement. * He gained support from landowners and the small bourgeoisie. * In 1922, the successful intervention of the Italian Blackshirts against trade unions and workers’ strikes allowed Mussolini to claim power. * To pressure the government, he organized the March on Rome, establishing a fascist dictatorship. * He took complete control over the country’s resources, suppressed freedom, and repressed any other options using the secret police OVRA.
b) Nazism
* Causes: Discontent with the Treaty of Versailles, economic crisis, unemployment, etc. * Nazism centered around the ex-soldier Adolf Hitler and the National Socialist German Workers’ Party, who fought the communists. * Hitler won the support of a large part of the middle class, who suffered greatly. * In the 1932 elections, the Nazi Party received 13.8 million votes, and Hitler was appointed Chancellor of Germany. * Once in power, he ended the Weimar Republic and established the Third Reich, through which he established a fierce dictatorship. * He also took control of the economy, education, and culture. * He promoted the superiority of the Aryan race and persecuted the Jews. * These actions provoked World War II.
c) End of the Pacific War
* The Americans had reconquered most of the territories occupied by the Japanese. * But Japan continued its fanatical defense, symbolized by the Kamikazes. * To force Japan to surrender, US President Truman decided to use a new weapon, the atomic bomb, which was dropped on the cities of Hiroshima and Nagasaki in August 1945.
5. The Weakness of Democracies
* The democracies attempted to isolate themselves from world problems (US isolation) or focus their attention on domestic issues. * The weakness of the democracies and the League of Nations’ failure encouraged aggression and eventually led to war. * The Munich Conference in 1938 was convened by Hitler following protests by France, Great Britain, and other powers over his policy of expansion. It ended with the democracies accepting Hitler’s promises.
6. Preparing for War
* Germany entered into the Rome-Berlin Axis alliance with Italy in 1936, which was renewed under the name”Pact of Steel” * Germany also entered into the Anti-Comintern Pact with Japan. * When Hitler seized the Danzig Corridor in 1939, France and Great Britain pledged their support to Poland. * To prevent the USSR from joining forces with the Allies, Hitler signed the Nazi-Soviet Pact with Stalin, after which he began the invasion of Poland. * In response, the Allies declared war on Germany.
