Maharani Gayatri Devi was the third Maharani consort of Jaipur from 1940 to 1949 through her marriage to Maharaja Sawai Man Singh II. Following her husband's signature for the Jaipur State to become part of the Union of India and her step-son's assumption of the title in 1970, she was known as Maharani Gayatri Devi, Rajmata of Jaipur.
Ethnically born in a Koch Rajbongshi Hindu family, her father was Maharaja Jitendra Narayan of Cooch Behar in West Bengal, and her mother was Maratha Princess, Indira Raje of Baroda, the only daughter of Maharaja Sayajirao Gaekwad III, and she was sister to Jagaddipendra Narayan, informally known as 'Bhaiya', who became the Maharajah of Cooch Behar.
Following India's independence and the abolition of the princely states, she became a successful politician in the Swatantra Party. Gayatri Devi was also celebrated for her classical beauty and became something of a fashion icon in her adulthood. She served 12 years in Swatantra Party, during which she was a prominent critic of Indira Gandhi's government. After her departure from politics, she lived a quiet life in her large estate, spending time with her grandchildren and on hobbies and leisure.
