August 9 in Indian History

1925

Kakori Train Action

On August 9, 1925, revolutionaries associated with the Hindustan Republican Association (HRA) seized government treasury money being transported by train near Kakori, close to Lucknow.

The action is closely associated with revolutionaries such as Ram Prasad Bismil, Ashfaqulla Khan, Rajendra Lahiri, Roshan Singh and Chandrashekhar Azad. It became one of the best-known episodes of the revolutionary phase of India's freedom struggle.

Exam Point: Kakori Train Action → August 9, 1925 → HRA. Do not confuse it with the later Hindustan Socialist Republican Association (HSRA).
1942

Quit India Movement – Arrests and Mass Resistance

After the AICC adopted the Quit India Resolution in Bombay on August 8, 1942, the British authorities arrested Mahatma Gandhi and other senior Congress leaders in the early hours of August 9, 1942.

With the top leadership jailed, the movement spread through demonstrations, strikes, underground activity and local resistance. Aruna Asaf Ali became an iconic figure of the movement and is remembered for unfurling the national flag at Gowalia Tank Maidan in Bombay.

Exam Point: August 8 = AICC resolution and Gandhi's address; August 9 = arrests and nationwide intensification.
1945

Atomic Bombing of Nagasaki

At 11:02 a.m. on August 9, 1945, Nagasaki was devastated by the second atomic bomb used in war, three days after Hiroshima.

Nagasaki's official peace material stresses the immense civilian destruction and the long-term suffering of hibakusha from radiation-related health effects. The city has since become a major global centre for peace education and nuclear-disarmament advocacy.

Exam Point: Hiroshima → August 6, 1945; Nagasaki → August 9, 1945.
1965

Singapore Became Independent

Singapore became an independent sovereign state on August 9, 1965 after separation from Malaysia.

Singapore later joined the United Nations on September 21, 1965 and became a member of the Commonwealth on October 15, 1965.

Exam Point: Singapore Independence Day / National Day → August 9.
