Lal Bahadur Shastri, India's second Prime Minister, died in Tashkent in 1966 after signing the Tashkent Declaration ending the 1965 Indo-Pakistani War. The cause of death was heart attack, though rumors persist about poisoning. Shastri was known for his honesty and simplicity, supported the White and Green Revolutions, and coined the slogan 'Jai Jawan Jai Kisan'.
