Raksha Bandhan or Rakhi is a Hindu festival and also Sikh festival, which celebrates the relationship between brothers and sisters. It is celebrated on the full moon of the month of Shraavana on August.
The festival is marked by the tying of a rakhi, or holy thread by the sister on the wrist of her brother. The brother in return offers a gift to his sister and vows to look after her. The brother and sister traditionally feed each other sweets.
Many Rajput Kings sacrificed their lives to protect their spiritual sisters. Humayun the great Mughal Emperor received a Rakhi from the queen Karmavati of Chittor and for that, Humayun carried out his sacred brotherly duty and protected her by opposing his own soldiers.
