The Imperialism of Free Trade

"The Imperialism of Free Trade" is an academic article by John Gallagher and Ronald Robinson which was published in The Economic History Review in 1953. The article was influential in the debate concerning theories of 19th century imperialism which, after John A. Hobson's Imperialism: A Study, had focused on economic motivation. Instead, Gallagher and Robinson claimed that the New Imperialism — "the new spate of imperial expansion that gathered momentum from the 1880s" — could be best characterised as a continuation of a long-term policy in which informal empire, based on the principles of free trade, was favoured over formal imperial control unless circumstances made such rule impossible. As well as reigniting scholarly interest in theorizing New Imperialism, the article helped launch the Cambridge School of historiography.

The arguments proposed in the article were later developed in a full-length book, Africa and the Victorians (1961), in conjunction with Alice Denny. The book put forward a subtly different explanation for European expansion in Africa, built around geopolitics and a strategy of protecting British India from encroachment by European powers. The strategic model and its relevance to East Africa was criticised for its limited documentary basis and sequential inconsistencies by John Darwin in 1997, a refutation that was further consolidated and contextualised by Jonas Gjersø in 2015.

Reviewing the debate from the end of the 20th century, historian Martin Lynn argues that Gallagher and Robinson exaggerated the impact. He says that Britain achieved its goal of increasing its economic interests in many areas, "but the broader goal of 'regenerating' societies and thereby creating regions tied as 'tributaries' to British economic interests was not attained." The reasons were:

The idea that free-trade imperial states use informal controls to secure their expanding economic influence has attracted Marxists trying to avoid the problems of earlier Marxist interpretations of capitalism. The approach is most often applied to American policies.
