Lal Bahadur Shastri (2 October 1904  – 11 January 1966) was the second Prime Minister of the Republic of India and a leader of the Indian National Congress party.
Shastri joined the Indian independence movement in the 1920s. Deeply impressed and influenced by Mahatma Gandhi, he became a loyal follower, first of Gandhi, and then of Jawaharlal Nehru. Following independence in 1947, he joined the latter's government and became one of Prime Minister Nehru's principal lieutenants, first as Railways Minister (1951–56), and then in a variety of other functions, including Home Minister. Shastri was chosen as Nehru's successor owing to his adherence to Nehruvian socialism after Nehru's daughter Indira Gandhi turned down Congress President K. Kamaraj's offer of premiership.
Shastri as Prime Minister continued Nehru's policies of non-alignment and socialism. He became a national hero following the victory in the Indo-Pakistan War of 1965. His slogan of "Jai Jawan Jai Kisan" ("Hail the soldier, Hail the farmer") became very popular during the war and is remembered even today.[2] The war was formally ended in the Tashkent Agreement of 10 January 1966; he died the following day, still in Tashkent, of a heart attack.
