Is World War 2 the Most Deadliest War in History?

World War 2 was a global conflict that took place between 1939 and 1945, involving the majority of the world’s nations. It is considered one of the deadliest conflicts in human history. The war resulted in the deaths of millions of people worldwide, both military personnel and civilians.

What Caused World War 2?

The causes of World War 2 are complex and varied. It began as a result of the aggression exhibited by Nazi Germany, led by Adolf Hitler, who sought to expand his territory and create a larger German empire.

The Treaty of Versailles, which ended World War 1, had imposed significant restrictions on Germany, including limitations on their military power and territorial control. Hitler felt that these restrictions were unfair and acted as a barrier to German expansionism.

The Impact of World War 2

The impact of World War 2 was far-reaching and long-lasting. The war resulted in the deaths of an estimated 70 to 85 million people worldwide. This number includes both military personnel and civilians who were killed as a result of direct or indirect actions related to the war.

Countries across Europe were devastated by the conflict, with many cities left in ruins as a result of bombing raids. The Holocaust resulted in the systematic murder of approximately six million Jews by Nazi Germany. The war also saw the use of atomic bombs for the first time, resulting in significant damage to Japanese cities Hiroshima and Nagasaki.


In conclusion, World War 2 was undoubtedly one of the deadliest conflicts in human history. The sheer scale of destruction caused by this global conflict has had long-lasting effects on countries around the world. Although it is difficult to determine an exact number due to discrepancies in record-keeping, it is estimated that between 70-85 million people lost their lives as a result of this catastrophic event.
