The World War II officially began on September 1, 1939, with Hitler’s invasion of Poland. This military action marked the true start of a conflict that would lead to the most devastating war in human history. To understand how we arrived at this point, we must look back to the aftermath of the World War I.
The Aftermath of World War I
After World War I, the Treaty of Versailles was imposed, ending the “Great War.” Germany emerged significantly weakened, losing territory and facing disproportionate reparations. The German populace sought a leader who could revive national pride and offer a vision for the future. In this volatile atmosphere, Adolf Hitler, a frustrated painter, seized the opportunity to channel public anger and ambitions.
The Rise of Adolf Hitler
Hitler rose to prominence by transforming the German Workers’ Party into the National Socialist German Workers’ Party (Nazi Party). The Nazi ideology was deeply nationalist and supremacist, with strong antisemitic and anti-Marxist sentiments. In 1923, Hitler attempted a coup d’état, resulting in imprisonment. During his time in prison, he authored Mein Kampf (“My Struggle”), which became the manifesto of Nazism despite its low literary quality. After his release, Hitler re-entered politics and, in 1932, narrowly won the election to become Chancellor of Germany. The following year, amidst a worldwide economic crisis, the Third Reich was established. Through an enabling act, Hitler dismantled the democratic institutions of the Weimar Republic, targeting Communist Party members and actively persecuting Jewish people.
Defying the Treaty of Versailles
In defiance of the Treaty of Versailles, Hitler rearmed Germany, establishing a powerful military with minimal protest from France and England. In 1938, he began his expansionist agenda by annexing Austria and later threatening war over the Sudetenland, a German-majority region of Czechoslovakia. To resolve this issue, representatives from Germany, France, England, and Italy met in Munich, excluding Czechoslovakia from discussions. In a display of weakness, British Prime Minister Chamberlain and French leaders appeased Hitler, a decision that would prove disastrous.
The Invasion of Poland
Hitler’s ambitions extended to Poland, which had been created by the Treaty of Versailles from territories taken from Germany, Austria, and Russia. In August 1939, the world was shocked when Hitler and Stalin signed the Molotov-Ribbentrop Pact, a non-aggression treaty. Only nine days later, Hitler invaded western Poland, and three weeks later, Soviet forces entered from the east. This invasion finally prompted Britain and France to declare war on Germany.
The “Phoney War”
Following the declaration, a period of inactivity ensued, dubbed the “Phoney War.” British troops were deployed to France, but both the French and British armies took defensive positions behind the Maginot Line. During this time, the Soviet Union invaded Finland, facing significant resistance, which led Hitler to underestimate the Soviet Red Army.
Blitzkrieg: The Lightning War
In May 1940, Germany broke the Phoney War by launching a simultaneous invasion of Luxembourg, Belgium, the Netherlands, and France. Utilizing a strategy known as Blitzkrieg, or “lightning war,” German forces swiftly encircled the Allied troops, leading to the Dunkirk evacuation, where over 300,000 Allied troops were rescued from French shores.
The Fall of France
Shortly after, France capitulated. On June 22, 1940, Hitler signed the armistice with France in the same railway carriage where Germany had surrendered in World War I. France was divided into two zones: the northern part, including Paris, was occupied by Germany, while Vichy France remained nominally independent but was a puppet regime allied with the Nazis.
Britain’s Resistance
Under Winston Churchill’s leadership, Britain rejected any peace agreement with Hitler. In retaliation, Hitler initiated the Battle of Britain, primarily an aerial conflict between the Luftwaffe and the Royal Air Force. During this intense battle, Churchill famously remarked, “Never in the field of human conflict was so much owed by so many to so few,” acknowledging the RAF’s critical role in defending Britain.
The Axis Alliance and Japan’s Expansion
In late 1940, Hitler sought to expand his alliance with countries like Hungary, Romania, and Bulgaria. However, Spain, led by General Franco, remained non-belligerent due to post-civil war economic difficulties. Meanwhile, Japan, having joined the Axis in 1939, launched aggressive campaigns in Asia, which escalated tensions with the United States.
The Attack on Pearl Harbor
On December 7, 1941, Japan launched a surprise attack on the U.S. naval base at Pearl Harbor. This attack, described by President Roosevelt as “a date which will live in infamy,” brought the United States into the war against Japan and subsequently against the Axis Powers, as Hitler declared war on the U.S.
Turning Points in the War
The entry of the U.S. into the war marked a significant turning point. In the Pacific, the American victory at the Battle of Midway in 1942 shifted momentum, while in Europe, Allied intelligence breakthroughs, including the decoding of Germany’s Enigma machine, significantly shortened the war.
Key Battles and Victories
In North Africa, Allied forces defeated German and Italian troops at El Alamein, preventing them from seizing the Suez Canal. In the Soviet Union, Hitler’s disastrous invasion of Stalingrad marked the beginning of the end for the Axis Powers, with the battle becoming one of the bloodiest in history.
The Legacy of the World War II
The World War II reshaped the global landscape and left an indelible mark on history. Its lessons continue to resonate today, reminding us of the consequences of unchecked ambition and the importance of international cooperation.
