Nehru met Gandhi for the first time in 1916 at the annual meeting of the Indian National Congress (Congress Party) in Lucknow. Gandhi was 20 years his senior. Neither seems to have made any initially strong impression on the other. Nehru did not assume a leadership role in Indian politics, however, until his election as Congress president in 1929, when he presided over the historic session at Lahore (now in Pakistan) that proclaimed complete independence as Indias political goal. Until then the objective had been dominion status.Nehrus close association with the Congress Party dates from 1919 in the immediate aftermath of World War I. This period saw a wave of nationalist activity and governmental repression culminating in the Massacre of Amritsar in April 1919, 379 persons were reported killed and at least 1,200 wounded when the local British military commander ordered his troops to fire on a crowd of unarmed Indians assembled for a meeting.When, late in 1921, the prominent leaders and workers of the Congress Party were outlawed in some provinces, Nehru went to prison for the first time. Over the next 24 years he was to serve another eight periods of detention, the last and longest ending in June 1945, after an imprisonment of almost three years. In all, Nehru spent more than nine years in jail. Characteristically, he described his terms of incarceration as normal interludes in a life of abnormal political activity.
His political apprenticeship with the Congress lasted from 1919 to 1929. In 1923 he became general secretary of the party for two years and again, in 1927, for another two years. His interests and duties took him on journeys over wide areas of India, particularly in his native United Provinces, where his first exposure to the overwhelming poverty and degradation of the peasantry had a profound influence on his basic ideas for solving these vital problems. Though vaguely inclined toward socialism, Nehrus radicalism had set in no definite mold. The watershed in his political and economic thinking was his tour of Europe and the Soviet Union during 1926
