Rani Padmavati or Padmini was a very beautiful and charming princess if Sinhaladweep (Sri Lanka) and wife of Rana Ratan Singh of Chittor.
Her story is narrated in a book called Padmavat written by Malik Jayasi. There is a lot of plot in the book but the gist is that Rani Padmini was a strong woman who did not let her spirits die when her husband was deceitfully captured by Khilji. She planned with Gora and Badal and they successfully brought back Ratansen while losing their lives eventually.
She along with Queen Nagmati committed Jauhar and Khilji entered in an empty Chittor where men had committed Saka and women had chosen dignity over atrocious slavery.
The story in Padmavat might be exaggerated and not totally accurate but there is no doubt that the warriors of chittor would never surrender their dignity in any way so Saka and Jauhar must be historically accurate.
