May 8, 1945, is celebrated as Victory in Europe Day (VE Day), the date on which the Allied powers accepted the unconditional surrender of Nazi Germany.
This event marked the end of the Second World War on the European continent, although the conflict continued in Asia until September of that same year.
The war, which began in 1939, was a global confrontation that profoundly transformed the politics, society, and international balance of the 20th century.
Causes of the Second World War
The causes of the conflict date back to the period following the First World War.
The Treaty of Versailles imposed territorial, military, and economic sanctions on Germany, generating social instability and political resentment.
The economic crisis of 1929 aggravated the situation and favored the rise of totalitarian regimes.
In Germany, Adolf Hitler promoted an expansionist policy aimed at recovering lost territories and expanding the German living space (Lebensraum).
The weakness of the League of Nations and the policy of appeasement practiced by France and the United Kingdom allowed Nazi Germany to annex Austria in 1938 and occupy the Czechoslovak region of the Sudetenland without an immediate military response.
The German invasion of Poland in September 1939 triggered the formal outbreak of war in Europe.
Development of the conflict: from Axis dominance to the turning point
During the first years of the war, the Axis powers—Germany, Italy, and Japan—achieved significant territorial gains.
Germany occupied much of Western Europe through rapid and coordinated campaigns, while Japan expanded its dominion in East Asia and the Pacific. However, starting in 1942, the balance began to shift.
On the Eastern Front, the Battle of Stalingrad, fought between Germany and the Soviet Union, halted the German advance and marked the beginning of their retreat.
In the Pacific, the naval Battle of Midway proved a decisive defeat for Japan against the United States, weakening its offensive capability.
In Western Europe, the Allied landings in Normandy in June 1944 allowed American, British, and Canadian forces to begin the liberation of France and advance toward Germany.
From that moment on, the military initiative clearly passed to the Allied side.
The end of the war in Europe and the continuation in Asia
The Soviet offensive from the east and the Allied advance from the west led to the fall of Berlin in May 1945.
On May 8, Germany signed its surrender, ending the war in Europe.
However, the conflict continued in Asia, where Japan was still fighting.
In August 1945, the United States dropped nuclear bombs on the Japanese cities of Hiroshima and Nagasaki.
These detonations caused massive destruction and thousands of civilian casualties, and led to the official Japanese surrender in September 1945, definitively closing the Second World War.
Global consequences of the war
The consequences of the conflict were worldwide.
Japan suffered extreme devastation. The atomic bombs completely destroyed Hiroshima and Nagasaki, causing hundreds of thousands of immediate deaths and subsequent deaths due to radiation.
Radioactive contamination caused health, environmental, and social effects for decades, leaving a deep mark on the population.
Despite this, Japan initiated a process of reconstruction under American occupation, adopted a new pacifist constitution, and, in a few decades, became one of the world's leading economic powers.
Europe was left devastated, with millions dead and cities destroyed, which prompted reconstruction plans such as the Marshall Plan.
The United States and the Soviet Union emerged as superpowers, initiating the Cold War.
The decolonization of Asia and Africa accelerated, and the political, technological, and moral impact of the conflict continues to influence contemporary history.
The United Nations was created with the goal of avoiding new global conflicts.
The discovery of the Holocaust led to the development of international human rights law.
The nuclear age began, marked by the balance of terror and the arms race.
Overall, it can be stated that the war redefined the world order and that its effects continue to influence current international politics.
