History of Hiroshima Day

The atomic bombing of Hiroshima was carried out on 6 August 1945 during the final phase of World War II. A US B-29 bomber known as the Enola Gay attacked the military and industrial centre of Hiroshima in the latter stages of World War II.

 

The aeroplane dropped the "Little Boy" atomic bomb, which was based on Uranium, at 8:15 a.m. local time. The death toll from severe burns, blast injuries, and acute radiation illness increased to over 1,40,000 by the end of 1945.

 

Japan unconditionally surrendered on August 15, 1945, ending World War II, following the United States' use of a second atomic weapon ("Fat Man") on Nagasaki 3 days later on August 9, 1945. 

Significance of Hiroshima Day

Hiroshima Day serves as a reminder of the catastrophic humanitarian consequences of nuclear warfare and the long-term suffering caused by radiation exposure.

 

The day encourages international efforts toward peace, nonviolence, and nuclear disarmament while serving as a reminder of the enormous devastation wrought by nuclear weapons.

 

To remember the victims, governments, international organisations, peace advocates, and people from all around the world take part in memorial services.

 

More than eight decades after the bombing, Hiroshima remains a powerful symbol of the human cost of war and the importance of preventing the use of nuclear weapons.
