5 Rupees (Lal Bahadur Shastri Birth Centenary)

Lal Bahadur Shastri served as India's second Prime Minister for just 19 months before dying in Tashkent in January 1966 — hours after signing a peace accord with Pakistan's Ayub Khan to end the 1965 war. The cause of death was officially recorded as cardiac arrest, though his family and various investigators have disputed that finding for decades. He remains the only Indian Prime Minister to have died on foreign soil while in office.
