The Lahore Session of the Indian National Congress in 1929 was a landmark event in Indian history for several reasons. One of the significant occurrences during this session was the sponsorship of a resolution condemning a bomb attack on the Viceroy by Jawaharlal Nehru.
Background:
The Lahore Session took place from December 29-31, 1929, under the presidency of Jawaharlal Nehru.
This session is primarily remembered for the adoption of the Purna Swaraj (Complete Independence) resolution. However, the session also dealt with other important resolutions, including the one related to the bomb attack on the Viceroy, Lord Irwin.
On December 23, 1929, just a few days before the Lahore Congress session, a bomb attack was carried out on the train of Lord Irwin, the then Viceroy of India. Fortunately, he escaped unhurt.
