Gandhi came back to active politics and attended the Calcutta session of the Congress in 1928. He now began to consolidate the nationalist ranks. The first step was to reconcile the militant left-wing of the Cingress. Jawaharlal Nehru was now made the President of the Congress at the historic Lahore session of 1929.
The Lahore session of the Congress gave voice to the new, militant spirit. It passed a resolution declaring Poorna Swaraj [Complete Independence] to be the Congress objective. On 31 December 1929 the newly adopted tricolour flag of freedom was hoisted. 26 June 1930 was fixed as the first Independence Day. The Congress session also announced the launching of a civil disobedience movement. But it did not draw up a programme of struggle. That was left to Mahatma Gandhi.
