Sahibzada is a princely style or title equivalent to, or referring to a young prince. This derivation using the Persian suffix -zada(h), literally 'born from (or further male/female descendant; compare Shahzada) a Sahib', was also (part of) the formal style for some princes of the blood of Muslim dynasties in the Indian sub-continent , e.g.:
the sons of a ruling Nawab of Arcot (the head of the family; political pensioners, the only princely title still recognized by the Indian Republic) are styled: Sahibzada (personal name) Khan Bahadur, not Nawabzada (literally 'son of the Nawab').
in Bahawalpur, in Pakistan, the younger sons of the ruling Nawab/Amir are styled: Sahibzada (personal name) Khan Abassi; but the Heir Apparent: Nawabzada (personal name) Khan Abassi, Wali Ahad Bahadur
in Baoni, the younger sons and other male descendants of the ruling Nawab, in the male line, were styled Sahibzada (personal name) Khan Bahadur, while the Heir Apparent was: Nawabzada (personal name) Khan, Wali Ahad Bahadur; either could be personally promoted to Nawab
in Bhopal, the grandsons of the ruling Nawab were styled: Sahibzada (personal name) Khan, while the Heir Apparent was the Wali Ahad Bahadur, the younger sons: Nawab (personal name) Khan Bahadur
in Jaoroa, more distant male relatives of the ruling Nawab then the sons (who were Nawabzada) were styled: Sahibzada (personal name) Khan
in Khudadad, Tippu Sultan's short-lived Muslim empire, the grandsons and other male descendants of the sovereign Padshah bahadur were styled: Sahibzada (personal name), until in 1860 the colonial (British) Indian Government extended to them the existing style for sons of the ruling Nawab: Shahzada (personal name) Sahib
in Malerkotla, where the Heir Apparent was Nawabzada (personal name) Khan Bahadur, the younger sons of the ruling Nawab were styled: Sahibzada (personal name) Khan Bahadur
in Savanur, where sons of the ruling Nawab were Nawabzada, the other male descendants in the male line: Sahibzada (personal name) Khan Sahib, and the more remote male descendants of the ruler: Sardar (personal name) Khan Sahib.
This could be further combined, e.g.:
in Hyderabad, a mainly Muslim state of the Nizam, every son of the ruler was fully styled Walashan Nawab (personal title), Sahibzada Mir (personal name) Khan Bahadur; in the case of the Heir Apparent, all this was followed by The Prince of Berar, with the style of His Highness, normally reserved for ruling princes with at least an 11 (later 9) guns-salute;
in Loharu, where the Heir Apparent was Nawabzada Mirza (personal name) Khan, both the younger sons, and male descendants, of a ruling Nawab, in the male line, were styled: Sahibzada Mirza (personal name) Khan.
in Murshidabad (present title-seat of the royal house of Bengal), the other sons and male descendants of the reigning Nawab, in the male line: Sahibzada Sayyid (personal name) Mirza;
in Sachin, the grandsons and other male descendants of the ruling Nawab, in the male line, were styled: Sahibzada Sidi (personal name) Khan Bahadur, while the Heir Apparent was Nawabzada Sidi (personal name) Khan Bahadur, Wali Ahad Sahib, and the other sons: Nawabzada Sidi (personal name) Khan Bahadur.
in Bengal, male members of Muslim zamindari families with distant connections to ruling or formerly ruling royal families, were styled Sahibzada if the head of the family was called sahib. It could be affixed to more titles or family names.
in Hangu, the grandsons of the male line of the ruling Sahib are styled as Sahibzada (personal name) Noor.
In Palanpur, the younger sons of the ruling Nawab, and other male descendants in the male line, were styled Sahibzada (personal name) Khan; but the Heir Apparent: Nawabzada (personal name) Khan, Wali-ahad Sahib.
Colonial and modern use
Sahib means "owner" in Arabic and was commonly used in the Indian Sub-continent as a courteous term in the way that "Mister" (also derived from the word "master") and "Mrs." (derived from the word "mistress") is used in the English language. It is still used today in the Sub-continent just as "Mister" and "Mrs.", and continues to be used today by English language speakers as a polite form of address.
The term sahib was applied indiscriminately to any person whether Indian or Non-Indian. This included Europeans who arrived in the Sub-continent as traders in the 16th Century and hence the first mention of the word in European records is in 1673.
Pukka sahib was also a term used to signify genuine and legitimate authority, with pukka meaning "absolutely genuine".
Sahiba is the authentic form of address to be used for a female. Under the British Raj, however, the word used for female members of the establishment was adapted to memsahib, a corruption of the English word "ma'am" which was added to the word sahib.
The same word is also appended to the names of Sikhgurus.
Coroner: "What kind of a man was Captain Cathcart?"
Duke of Denver: "Well - he was a Sahib and all that. I don't know what he did before joining up in 1914. I think he lived on his income; his father was well off. Crack shot, good at games, and so on."
This title (pl. musāhibān), etymologically the active part. of to associate, or consort (with), means originally companion, associate, friend (the abstract term is musāhabat); not unlike the Hellenistic Greek Philos and the Latin Comes in the Roman empire, it became a title for a favourite (of a Sahib, especially a prince), and such 'personally close' positions as aide-de-camp, in some princely states even a Minister.
Other compound titles
Burra sahib; "big man" or important person (Burra meaning Great in India)
