The 32-year-old actor, who plays the character of the most powerful ruler of the Khalji dynasty, took to his Twitter handle and posted his portrait as Khilji with blood stains on it.
The picture was captioned, "And it's a wrap! Goodbye Alauddin. 1 year and a few weeks later, I bid thee farewell. May your restless soul find its peace... #Khilji"
The movie is based on Rani Padmini, a legendary Hindu Rajput queen, mentioned in 'Padmavat', an Avadhi language epic poem written by Sufi poet Malik Muhammad Jayasi in 1540.
According to Padmavat, she was the wife of Ratan Sen (called Rawal Ratan Singh in later legends), the Rajput ruler of Mewar.
In 1303, Alauddin Khilji, the Turkic ruler of the Delhi Sultanate, laid siege to the Chittor Fort in Rajputana.
Rani Padmini is said to have committed jauhar (self-immolation) along with all the other women of the city to protect their honour.
The men of the city stormed out in a final mortal sally to kill as many enemies before falling.
Sanjay Leela Bhansali's epic saga, 'Padmavati', has been embroiled in controversies with Rajput Karni Sena objecting to the film's release.
