Bhangarh got attacked by ajabgarh

Bhangarh was attacked by the neighboring kingdom of Ajabgarh. There was a fierce battle which Bhangarh lost and Rani Ratnavati herself died in the battle. The town has been uninhabited ever since.

Another version is that when Ratnavati threw the oil away and as the oil struck the ground it turned into a boulder, which crushed Singhia. Dying, the magician cursed the palace with the death of all who dwelt in it.

Some even say that the princess Ratnavati has taken birth somewhere else and that the fort and the empire of Bhangarh is waiting for her return to put an end to the curse.

There remains to be however another version of this story wherever Ratnavati herself is blamed for the doom of this town. In the first version of this lore, Ratnavati before marriage was in love with a poor man in her father's kingdom. They both knew that their marriage was out of question as Ratnavati was a princess and her lover was just a poor farmer but still could not help but falling madly in love with each other. As it is often shown in the movie, Ratnavati would sneak out of the palace when no one was looking to spend time with the poor boy. On one such instance, they were both caught red-handed by Ratnavati's father, the king. Sensing that her lover would probably be hanged for the crime that he committed by falling in love with a princess, Ratnavati made a pact with her father that she would marry as per his wishes only as long as he forgives the boy and grants him his life. Her father agreed and she was married off to the King of Bhangarh but she always remained in loved with the same boy and could never give her heart to her husband. The boy too did not back out and followed Ratnavati to Bhangarh dressed as a poor beggar and Tantrik. Ratnavati too found out about his presence in Bhangarh and they started meeting each other again. As it happened before, they were again caught by the king, this time Ratnavati's husband who doomed them both to death. Watching her beloved getting beheaded right in front of her eyes, Ratnavati cursed the king and town of Bhangarh to perish right after her death.

Second version of this story is that Ratnavati was in love with Jai Singh of Jaipur and because of this love affair, he kept attacking the town of Bhangarh until it was in ruins. His sole intention was to kill the king, win over Bhangarh as a part of his kingdom and Ratnavati as his wife in which he finally succeeded but at the cost of Bhangarh.
