Definition
A nabob was, in its primary historical sense, a governor of a province under the Mughal empire of Hindustan. Over time the title detached from any governing office and became an honorific conferred on men of high rank or great wealth, with no administrative function attached. In the legal dictionary tradition, the term appears not as a term of art but as a defined title — one whose legal significance depended on whether it carried governing authority or had been reduced to mere social distinction.
Common Language
Modern common usage (Wiktionary): An Indian ruler within the Mughal empire; someone of great wealth or importance; a person with a grandiose style or manner.
Historical common usage (Webster's 1913): A deputy or viceroy in India; a governor of a province of the ancient Mughal empire. By extension, one who returns to Europe from the East with immense riches; hence, any man of great wealth.
The legal dictionaries narrow what common usage treats broadly. Where popular language freely applies "nabob" to any wealthy or ostentatious person, the legal tradition insists on the distinction between a nabob who held actual provincial authority and one who bore only an empty title. That distinction mattered in colonial-era legal questions about jurisdiction, treaty rights, and the authority of Indian rulers to enter binding agreements.
Common Confusion
The term is sometimes read as synonymous with "nawab" (the more precise transliteration), and the two are in fact the same word at different stages of anglicization. In legal and historical sources predating the mid-nineteenth century, "nabob" is the standard spelling in English-language texts, including court records and East India Company documents. Researchers should not treat the spelling difference as marking a substantive legal distinction — it does not.
Why It Matters in Research
For most researchers, NABOB will appear in the Law Mind corpus not as an operative legal term but as a title embedded in disputes involving the East India Company, colonial governance, treaty interpretation, and prize or property claims arising from British India. The key research trap is assuming the title carried legal authority. The historical dictionaries are explicit: by the later Mughal period, the title had in many cases been stripped of any governing function and was honorific only. A document referring to a "nabob" therefore tells you nothing by itself about whether that individual held jurisdiction over persons or territory.
Chronology matters. Pre-1757 (before Plassey), nabobs generally retained meaningful provincial authority. Post-1757, as Company power expanded, the title increasingly described a figure whose formal dignity survived but whose actual legal competence had been absorbed by or made subordinate to Company administration. Sources from different periods of this transition use the same word to describe legally very different figures.
The term also migrated into British domestic satire and political discourse to describe Company servants who returned to England with fortunes — a usage with no legal content but one that colors some of the period sources researchers may encounter. Wiktionary's third sense ("a person with a grandiose style") reflects this satirical register, which was well established by the late eighteenth century.
Bouvier's citation to "Whart." (Francis Wharton's legal works) alongside Wilson's Indian Glossary suggests the term was treated as requiring specialized reference even in the American legal tradition — it was not assumed to be self-explanatory.
Historical Dictionary Support
All three historical sources — Black's (1st and 2nd editions) and Bouvier's — give substantially identical definitions, each tracing the word to Wilson's Indian Glossary. The uniformity signals that compilers were drawing on the same colonial-administrative source rather than synthesizing independent legal usage. None of the three entries develops the term beyond its definitional core; none addresses the legal consequences of holding the title, the distinction between a reigning and a pensioned nabob, or the Company's practice of recognizing certain nabobs as treaty counterparties.
Webster's 1913 is actually more informative on the social evolution of the term than the legal dictionaries are, capturing the English popular usage that the legal sources ignore entirely. The legal dictionaries define the original institution; they do not track what the word meant in practice by the time most Anglo-Indian legal disputes were actually litigated.
What the historical sources miss: the legal significance of the distinction between a nawab-nazim (who combined revenue and criminal jurisdiction) and a purely titular nabob became critical in cases involving the Permanent Settlement and later in arguments about paramountcy. None of the dictionary entries address this, and researchers working on those questions will need to move quickly beyond the dictionaries to administrative and treaty records.
Jurisdictional Note
The term arises almost exclusively in the context of British Indian administration and East India Company law. It has no operative meaning in American law except where it appears in historical documents touching on trade or prize cases involving the subcontinent. In English law, its significance is historical rather than current.
