Hajji Nawab Kalb Ali Khan Bahadur (1832 - 23 March 1887) was a Nawab of the princely state of Rampur from 1865 to 1887. Succeeding his father, Sir Nawab Yusef Ali Khan Bahadur, he continued his father's good works, expanding the Rampur library, constructing the Jama Masjid costing Rs.3 lakhs and encouraging the spread of education, irrigation, architecture, literature and art in general. A gifted ruler, Sir Kalb Ali Khan was highly literate in Arabic and Persian and patronised scholars from across India and the Islamic world. He was a member of John Lawrence's governance council from 1878 to his death, attended the Delhi Durbar of Queen Victoria and was granted a personal salute of 17-guns.
He was also an Urdu-language writer and essayist and poet of ghazals.[1]
He was succeeded at his death in 1887, aged 55, by his son, Muhammad Mushtaq Ali Khan Bahadur.
