WHEN THE HISTORIAN John Guthrie Smith majestically surveyed the landed estates of the West of Scotland in The Old Country Houses of the Old Glasgow Gentry in 1878, he cited one family in particular that epitomised Glasgow's elite ‘sugar aristocracy’:

In his landmark study The Price of Emancipation, Nicholas Draper underlined the exceptional standing of the great merchant house of John Campbell, senior, & Co. On the abolition of plantation slavery in 1834, partners in the firm received over £73,000 compensation, which ranked the merchant house as the eighth-largest ‘mercantile beneficiary’ in Great Britain and the highest in Scotland. Given their prominence and the availability of business records, it is surprising the firm has not attracted serious attention by historians. This case study will address this lacuna, thus adding to a developing historiography on Scottish– West India merchants, planters and firms in the colonial period.

The rise of the firm in Glasgow, including capital stock and partnership structure, can be traced in some detail from surviving business records. This will be placed in a transatlantic context. The colonial activities of the firm will be illustrated through dealings with correspondents in Scotland and the Caribbean. Early commercial ventures in Grenada and Carriacou provided the foundation for the firm's later expansion into the frontier colony of Demerara, which was joined with Berbice and Essequibo to become British Guiana in 1831. Colonial operations will be outlined through deeds and mercantile correspondence. Finally, the firm's compensation claims and the financial interests of co-partners will be traced through parliamentary sources, and wills and confirmation inventories generated on the death of individuals concerned.
