The 1929 Lahore Session of the Indian National Congress, presided over by Jawaharlal Nehru, is a landmark in the Indian Freedom Struggle for the following reasons:
- Purna Swaraj Resolution: The Congress passed the historic 'Purna Swaraj' (Complete Independence) resolution, officially shifting its goal from 'Dominion Status' to total independence from British rule.
- Symbolic Act: On the midnight of December 31, 1929, Jawaharlal Nehru hoisted the tricolour flag on the banks of the River Ravi amidst slogans of 'Inquilab Zindabad'.
- Independence Day: The Congress fixed January 26, 1930, as the first Independence Day, to be celebrated by the people across the country.
Why other options are incorrect:
- Option A: While 'Swaraj' was discussed earlier (e.g., 1906), the 1929 session specifically defined it as 'Purna Swaraj' or complete independence.
- Option C: The Non-Cooperation Movement was launched much earlier, in 1920.
- Option D: The Congress decided to boycott the First Round Table Conference during this session. The decision to participate in the Second Round Table Conference was only taken later, following the Gandhi-Irwin Pact in 1931.
