Jai Jawan Jai Kisan was a slogan given to India by the Prime Minister of India Lal Bahadur Shastri in 1965. It means hail the soldier and hail the farmer. Soon after Shastri took over the prime ministership of India after Nehru’s death. India was attacked by Pakistan. At the same time there was scarcity of foodgrains in country. Shastri gave the slogan Jai Jawan Jai Kisan to enthuse the soldiers to defend India and simultaneously cheering farmers to do their best to increase the production of food grains to reduce dependence on import. It became a very popular slogan. After Pokaran tests in 1998 Atal Bihari Vajpayee added Jai Vigyan (Hail knowledge) to the slogan to underline the importance of knowledge in India’ progress.
