The letters allege that the film presents Rani Padmavati in a wrong manner.
"Twenty-seven letters addressed to the president were submitted to the Additional District Magistrate (ADM)," Rajput Karni Sena's Ratlam district women's wing vice president Mangla Deora said.
"We demanded that the president should either grant us permission to embrace death, as we are not able to protect the honour of Rani Padmavati, or stop release of the movie," she said.
Agitations were held in Indore, Sagar, Guna, Bhopal, Ratlam and other towns in Madhya Pradesh against the movie today.
The Supreme Court had earlier paved the way for all-India release of 'Padmaavat' and stayed notifications and orders issued by Madhya Pradesh, Rajasthan and Gujarat - all ruled by the BJP - prohibiting exhibition of the film.
