Indira Gandhi was an Indian politician who served as the third Prime Minister of India from 1966 to 1977 and again from 1980 until her assassination in 1984. She was India's first and, to date, only female prime minister, and a central figure in Indian politics as the leader of the Indian National Congress. Gandhi was the daughter of Jawaharlal Nehru, the first prime minister of India, and the mother of Rajiv Gandhi, who succeeded her in office as the country's sixth prime minister. Furthermore, Gandhi's cumulative tenure of 15 years and 350 days makes her the second-longest-serving Indian prime minister after her father. Henry Kissinger described her as an "Iron Lady", a nickname that became associated with her tough personality since her lifetime.
