Scholars have emphasized the importance and autonomy of African intermediaries in European imperial projects. However, intermediaries have not been studied as founders of (proto) colonial administrations. Between 1840 and 1874, the inchoate British establishment on the Gold Coast was largely a project of Anglo-African merchants, rooted in their political visions of “progress.” Merchants like James Bannerman provided infrastructure, institutions, and material form to the administration and intended it as a force for development. Ultimately, the British administration exercised its hegemony through Euro-African infrastructures, spaces, and ideas. Consequently, merchants like Bannerman undermined their local networks, rulers, and dependents who opposed British domination.
