Another famous historical rakhi story is that of Rani Karnavati (queen Karnavati) of Chittor and Mughal Emperor Humayun, which dates to 1535 CE.
When Rani Karnavati, the widowed queen of the king of Chittor, realized that she was not in a position to defend against the invasion by the Sultan of Gujarat, Bahadur Shah, she sent a Rakhi to then Mughal Emperor Humayun.
Touched by the queen’s gesture, the Emperor immediately set off with his troops to defend the state of Chittor. Humayun could not arrive on time, and by the time he reached, Bahadur Shah had already managed to sack the Rani’s fortress.
And sadly, Rani, along with other Rajput ladies committed Jauhar to save their honor. Jauhar is an ancient Rajput ritual which amount to burning to death of the queens and female royals of Rajput kingdoms to save their honor when facing defeat at the hands of an enemy
Although contemporary commentators and memoirs do not mention the Rakhi episode and some historians have expressed skepticism about it, it still finds mention in one mid-seventeenth century Rajasthani text.
