In 1960, in Ceylon, Sirimavo Bandaranaike became the first woman to become prime minister in contemporary world history.
At the time she became Prime Minister of India, she was 48 years old. She was born in 1917 as the daughter of Jawaharlal Nehru, also Indian Prime Minister, the first in history. Her original name was Indira Nehru, and she got her last name after marrying Feroze Gandhi. Interestingly, neither Indira nor Feroze was related to the famous Mahatm Gandhi, despite the same surname.
