Kuriyedathu Thatri or Kuriyedathu Savitri was a Nambuthiri woman from Kerala, India, known for going through the Smarthavicharana (cast based trial for adultery) in 1905.[1] Often called as Thathri Kutty, her Smarthavicharam is considered as the most controversial one held in Kerala as it shocked the core of the patriarchal and misogynistic society and culture in the state.[2] She is considered by many as one of the first feminists from Kerala who fought against the patriarchy that dominated the state.[3] Following the trial of Thathri, a council called Yogakhsemam was formed under the leadership of a few revolutionary Namboothiri men who promoted ideas such as the relaxation of marriage rules and abolishing the practiceof Sambandham.[4] Her trial was a turning point in Kerala's history for women and their liberation.
