Rai Bahadur (also Rao Bahadur in South India), abbreviated R.B., was a title of honour bestowed during British rule in India to individuals for faithful service or acts of public welfare to the Empire. From 1911, the title was accompanied by a medal called a Title Badge. Translated, Rao means "prince", and Bahadur means "brave" or "most honourable". Bestowed mainly on Hindus, the equivalent title for Muslim and Parsi subjects was Khan Bahadur. For Sikhs it was Sardar Bahadur.
Those awarded the Rao Bahadur title were usually drawn from the lower rank of Rai Sahib, both of which were below the rank of Dewan Bahadur. These titles were subordinate to the two orders of knighthood: the Order of the Indian Empire and the higher Order of the Star of India. A holder of a Rai Sahib, Rai Bahadur or Dewan Bahadur title came lower in the order of precedence.
