Rani Shri Amrit Kaur Sahiba of Mandi was born in 1904, the only daughter of Jagatjit Singh Sahib Bahadur and his fourth wife, Rani Kanari Sahiba. Jagatjit reigned as maharaja between 1890 and 1947 in Kapurthala, northern Punjab.
Amrit received her education at a progressive girls' boarding school in Eastbourne, England, where she played tennis, led a five-piece jazz band and acted in plays. She was then sent to Paris. Amrit was given away in marriage in 1923 to the Raja of Mandi Joginder Sen Bahadur. The couple toured Europe soon after their wedding, and were received in London by King George V and Queen Mary. After five months, they returned to Mandi, India, and the couple had a son and a daughter, Tikka Yashodan Singh (born 1923) and Princess Nirvana Devi (born 1929). In an interview by the New York Herald Tribune in 1927, Amrit expressed determination to fight for the poorest and most marginalised women. When her husband took a second wife, Amrit left India and her children for Paris in 1933 and never returned.
Kaur spent some time in the United States before returning to Paris just as World War II broke out. She was arrested on 8 December 1940 by the Gestapo in occupied Paris "on the accusation of having sold her jewelry to help Jews leave" France and imprisoned in the internment camp Besançon. Amrit's father wrote to the British Foreign Office and to Marshal Pétain, asking for help in obtaining her release. The Germans offered to exchange Amrit for one of their spies imprisoned in India, but a British official decided that her repatriation was "not of sufficient political importance" to justify such a deal. Kaur died in London in 1948. The first female Indian cabinet minister, Amrit Kaur, was her father's cousin.
In 2022, an Italian journalist for the Corriere della Sera, Livia Manera Sambuy, wrote a biography, Il segreto di Amrit Kaur, that was published in English as In Search of Amrit Kaur in 2023.
