Hiroshima Day History
1: Who was the first woman President of India?
On August 6, 1945, Hiroshima Day marks the day when the American B-29 bomber, carrying the nuclear weapon “Little Boy,” flew over Hiroshima. This bomb, containing 64 kilograms of enriched uranium, was designed to trigger a nuclear fission chain reaction. The survivors of the bombing, known as Hibakusha—a Japanese term for those affected by the atomic bombings—recall that they recognized the aircraft as American because no Japanese plane could reach that altitude at the time. Brigadier General Paul Tibbets, piloting the B-29, released the bomb at 7:30 AM.
The bomb descended for 45 seconds, reaching 6,000 feet above the city before detonation. At 8:15 AM, the chain reaction ignited, unleashing a devastating explosion that obliterated Hiroshima. The impact was catastrophic, killing approximately 140,000 people and leaving lasting effects from nuclear radiation. Even today, the remnants of Hiroshima’s shattered buildings stand as solemn memorials to this dark chapter in history, serving as a poignant reminder on Hiroshima Day of the enduring legacy of nuclear warfare.

Start Learning!Why Hiroshima Bombings?
Why they Selected Hiroshima?
Reflecting on the events of World War II, the bombings of Hiroshima and Nagasaki reveal the profound cruelty and inhumanity of the conflict. While wars typically involve military forces and strategies, the bombings of these Japanese cities starkly deviated from this norm by targeting civilian populations. Hiroshima, chosen as the site for the first atomic bomb, was not only a densely populated city but also a crucial military and trade hub with significant strategic importance. At the time, Hiroshima was considered the heart of Japan, integral to its economic and military infrastructure.
The decision to bomb Hiroshima was driven by the desire to induce a swift surrender from Japan by creating immense devastation and chaos. The impact of the Hiroshima bombing was intended to demonstrate the overwhelming power of the United States and compel Japan to capitulate. Despite the devastating effects of the Hiroshima attack, the U.S. proceeded to bomb Nagasaki just three days later. This second bombing further pressured Japan, leading to its eventual surrender and the conclusion of World War II.
The Consequences and Impact of the Hiroshima Bombings.
The devastation caused by the atomic bombings of Hiroshima was immense, with around 140,000 people killed instantly. However, the impact extended far beyond this figure, as survivors, known as Hibakusha, endured severe health issues due to radiation exposure, including various diseases and genetic disorders.
Hiroshima, once a thriving, highly developed city, was left in ruins. Yet, after 75 years, the city has remarkably rebuilt itself and regained its development. Today, Hiroshima stands as a symbol of resilience and peace. The Hiroshima Peace Memorial Park now commemorates the tragic events of the atomic bombing. Among its notable landmarks is the Genbaku Dome, also known as the Atomic Bomb Dome. Originally built in 1915, this building was remarkably resilient, with its dome designed to withstand natural disasters. Despite its proximity to the bomb’s hypocenter—just 200 meters away—the Genbaku Dome survived the explosion in a partially intact state. Its preservation serves as a poignant reminder of the devastation. In 1996, UNESCO recognized the Atomic Bomb Dome as a World Heritage Site, acknowledging its historical significance.
While the Peace Memorial Park solemnly preserves the memory of the bombings, the rest of Hiroshima has flourished and developed in modern times, reflecting the city’s remarkable recovery and commitment to peace.
The Historical impact was different. It created two sections in the world. One, the people who realise the dangerous and devastating effect of nuclear bombs on humanity. Two, the possibilities of destruction by atomic bombs for capturing power. The first category was the normal civilian people and the second category was the power enjoying people. The nations in the world started creating nuclear weapons secretly and publicly. After the second world war when the cold war began most of the nations were busy in equipping themselves with nuclear weapons if another war sprouted.
The cold war prevailed in the world for a period of 1947 to 1991. At this time the nations were busy in building their own nuclear weapons. On the other side peace enforcing organizations like the United Nations Organization started their mission to stop all the nations from producing and storing nuclear weapons. In 1970 a treaty named Nuclear Non-Proliferation Treaty (NPT) came into force between the nations banning them to produce nuclear weapons further. Another treaty named Comprehensive Nuclear Test Ban Treaty (CTBT) came into force in 1996 as part of the conference of Disarmament forcing nations not to test nuclear weapons. The other major treaty is Nuclear Ban Treaty or rather expanded as Treaty on Prohibition of Nuclear weapons which is the first ever legally binding agreement to comprehensively prohibit nuclear weapons, with the goal of leading towards their total elimination. It was passed on 7 July 2017.
NPT is the treaty signed by most of the nations. But India has not signed NPT yet. Because India believes that the treaty is a pseudo peace making treaty because of the provisions. The countries who produced nuclear weapons are allowed to store the weapons according to NPT but prohibited to produce more. But the countries who have not produced yet don’t have the right to produce thereafter. The countries who were at the head of the drafting of the policy and the countries who produced more weapons are the same and it shows their military diplomacy. So India doesn’t believe in the NPT.
