What Is the History of 2nd World War?

The Second World War was one of the deadliest and most devastating wars in human history. It lasted from 1939 to 1945 and involved the majority of the world’s nations, including all of the great powers, organized into two opposing military alliances: the Allies and the Axis. The war was fought across multiple continents, with major engagements in Europe, Asia, Africa, and the Pacific.

The Causes of World War II

The roots of World War II can be traced back to several factors, including unresolved tensions from World War I, economic instability caused by the Great Depression, and aggressive territorial expansion policies pursued by fascist regimes in Europe and Asia. These factors eventually led to a series of escalating diplomatic crises that culminated in a global conflict.

The Major Players

The major players in World War II were the Allied Powers – led by the United States, Great Britain, and the Soviet Union – and the Axis Powers – led by Germany, Italy, and Japan.

The Course of the War

World War II began on September 1st, 1939 when Germany invaded Poland. This prompted Britain and France to declare war on Germany. Over time, other countries joined both sides of the conflict.

In June 1941, Germany launched Operation Barbarossa – a massive invasion of Soviet territory. This opened up a second front on which Germany had to fight.

In December 1941, Japan attacked Pearl Harbor which brought America into the war. The United States quickly became one of the leading contributors to Allied forces.

After years of brutal fighting across multiple theaters of war, Allied forces finally gained an upper hand in Europe with D-Day landings on June 6th , 1944 followed by liberation of France. Meanwhile in Asia , American used Atomic bomb against Japan which ultimately forced them to surrender on August 15th , 1945.

The Aftermath of World War II

The Second World War had a profound impact on the world. It resulted in the deaths of over 70 million people and caused significant economic and social upheaval. The war also led to the formation of the United Nations, a global organization dedicated to promoting peace and cooperation between nations.

In Europe, the war led to the division of Germany into two separate countries – West Germany and East Germany. It also resulted in the establishment of communist governments in several Eastern European countries.

In Japan, the war ended with the country’s unconditional surrender and its subsequent occupation by Allied forces. This eventually led to Japan’s transformation into a democratic nation.


In conclusion, World War II was a devastating conflict that had far-reaching consequences for the world. Its causes were complex and multifaceted, but ultimately it was a result of unresolved tensions from World War I and aggressive territorial expansion policies pursued by fascist regimes. While it resulted in significant loss of life and destruction, it also played a pivotal role in shaping the course of modern history.
