INTRODUCTION

The Second World War (1939–1945) was a global conflict that involved major
world powers, leading to unprecedented destruction and loss of life. It was fought
between the Allied Powers—including the United States, the Soviet Union, the United
Kingdom, and China—against the Axis Powers, primarily Germany, Italy, and Japan.
The war affected millions of people, reshaping international relations and world politics1.

The war was largely fueled by unresolved tensions from World War I, particularly
the harsh conditions imposed by the Treaty of Versailles. Economic depression, the rise
of totalitarian regimes, and aggressive expansionist policies further escalated global
tensions. The failure of international peace organizations, such as the League of Nations,
also contributed to the outbreak of the war.

The significance of World War II extends beyond its military conflicts; it led to
profound political, economic, and social changes worldwide. The war resulted in the
establishment of the United Nations (UN), the beginning of the Cold War, and the
eventual decolonization of many nations. This assignment aims to explore the causes, key
events, and consequences of the war.
 2

CAUSES OF THE SECOND WORLD WAR

One of the major causes of World War II was the Treaty of Versailles (1919),
which ended World War I but left Germany with severe economic and political burdens.
The treaty forced Germany to accept full responsibility for the war, imposed heavy
reparations, and led to territorial losses. These conditions created deep resentment among
Germans, setting the stage for the rise of Adolf Hitler and the Nazi Party, who promised
to restore Germany’s power.

Another significant factor was the rise of totalitarian regimes in Germany, Italy,
and Japan. These countries, led by Hitler, Benito Mussolini, and Emperor Hirohito,
sought to expand their territories and establish authoritarian rule. Germany aimed for
European domination, Italy wanted to expand its influence in Africa, and Japan pursued
territorial expansion in Asia. Their aggressive policies led to conflicts with other nations.

The failure of the League of Nations, which was created to maintain global peace
after World War I, also contributed to the outbreak of the war. The League lacked
enforcement power and failed to prevent acts of aggression, such as Japan’s invasion of
Manchuria (1931), Italy’s invasion of Ethiopia (1935), and Germany’s remilitarization of
the Rhineland (1936). These unchecked aggressions encouraged further violations of
international agreements.

Another cause was the policy of appeasement, mainly followed by Britain and
France, which allowed Hitler to expand German territory without consequences. The
Munich Agreement (1938) permitted Germany to annex Czechoslovakia’s Sudetenland,
in the hope of avoiding war. However, Hitler continued his expansion, showing that
appeasement only emboldened aggressive leaders3.

The immediate trigger of World War II was Germany’s invasion of Poland on

September 1, 1939. Britain and France, having guaranteed Poland’s independence,
declared war on Germany on September 3, 1939. This marked the official start of the
war, as other nations soon became involved, leading to a full-scale global conflict1.

MAJOR EVENTS AND TURNING POINTS

The war began with Germany’s invasion of Poland on September 1, 1939, leading
Britain and France to declare war on Germany. Soon after, Germany used a rapid military
strategy called Blitzkrieg (lightning war) to conquer much of Europe, including France in
1940. During this time, the Battle of Britain (1940) took place, where the British Royal
Air Force successfully defended the country against German air raids, marking Hitler’s
first major failure3.

In 1941, the war expanded with two critical events. First, Germany launched
Operation Barbarossa, an invasion of the Soviet Union, breaking their previous non-
aggression pact. The harsh Russian winter and Soviet resistance slowed Germany’s
advance, leading to heavy German losses. Second, on December 7, 1941, Japan attacked
Pearl Harbor, bringing the United States into the war. The U.S. entry shifted the balance
of power in favor of the Allied Forces2.

One of the most significant turning points was the Battle of Stalingrad (1942–
1943), where the Soviet Union decisively defeated Germany, marking the beginning of
the German retreat from Eastern Europe. In North Africa, the Allies defeated German
forces in 1943, allowing them to invade Italy, which led to Mussolini’s downfall. These
victories weakened the Axis Powers and strengthened Allied momentum.

Another major event was the D-Day invasion on June 6, 1944. Allied forces, led
by the U.S., Britain, and Canada, launched a massive amphibious assault on Normandy,
France, successfully liberating Western Europe from German control. Meanwhile, in the
Pacific, the U.S. adopted an "island-hopping" strategy, winning key battles like Midway
(1942) and Iwo Jima (1945) to weaken Japan’s hold in the region4.

The war ended in 1945 with two key events. Germany surrendered on May 8,
1945 (V-E Day) after the Allies captured Berlin, and Hitler committed suicide. In the
Pacific, Japan refused to surrender until the U.S. dropped atomic bombs on Hiroshima
 4

and Nagasaki on August 6 and 9, 1945. Japan surrendered on August 15, 1945 (V-J Day),
officially bringing the war to an end.

CONSEQUENCES OF THE WAR

The Second World War caused massive human and material losses, with an
estimated 70-85 million deaths, including millions of civilians. The Holocaust, carried
out by Nazi Germany, resulted in the genocide of six million Jews and other targeted
groups. Cities across Europe and Asia were destroyed, economies collapsed, and many
nations faced severe food shortages and displacement crises.

One of the war's most significant outcomes was the establishment of the United
Nations (UN) in 1945, replacing the failed League of Nations. The UN was created to
promote international peace, human rights, and economic development. Additionally, the
war led to the division of Germany into East and West Germany, marking the beginning
of the Cold War between the United States and the Soviet Union5.

The war also accelerated the decolonization movement, as European powers,

weakened by the war, struggled to maintain control over their colonies. Countries in
Africa, Asia, and the Middle East pushed for independence, leading to the eventual
collapse of colonial empires. Economically, the war reshaped global trade, with the U.S.
and Soviet Union emerging as superpowers, setting the stage for geopolitical tensions in
the following decades1.

CONCLUSION

World War II was one of the most devastating conflicts in history, reshaping global
politics, economies, and societies. The war demonstrated the dangers of totalitarian
regimes, aggressive expansionism, and the failure of diplomatic efforts. While it led to
the creation of the United Nations and the decolonization of many nations, it also gave
rise to new tensions, particularly between the U.S. and the Soviet Union. The lessons of
World War II continue to influence international relations today, emphasizing the need
for global cooperation and peace.
