In the 1870s Lord Carnarvon, the British secretary of state for the colonies, attempted to unite the colonies and republics of South Africa into a selfgoverning (that is, settler-governed) dominion under the British flag, which he hoped would extend northwards to the Zambezi. So grandiose a scheme was clearly something more than the attempts at imperial retrenchment that earlier proposals for union had been. But there is little agreement among historians on the reasons for it. Until the publication of Goodfellow's work in 1966,1 the standard work on the subject was C. W. de Kiewiet's The Imperial Factor in South Africa.2 De Kiewiet, the least dogmatic of historians, gave no single or definite answer to the question of why Carnarvon wanted to confederate South Africa. Perhaps he gave the greatest stress, as Carnarvon himself did, to the necessity for a uniform native policy, the desire for which on Carnarvon's part De Kiewiet tended to see in humanitarian terms. De Kiewiet, like his mentor, W. M. Macmillan, belonged to what might be called the Liberal-Imperial school of South African historiography, which saw the imperial connection as a counterweight to settler rapacity and lamented that it had not been more effective. The view that the motive, or even a motive, behind Carnarvon's confederation scheme was a desire to protect the black population of South Africa from the whites, is not one that can survive a reading of Goodfellow. He makes it clear that the impulses behind it were not at all liberal. The South Africa Act of 1877, as originally drawn up by Carnarvon and his advisers, was more restrictive than that drawn up by white South Africans in 1910, since it excluded non-whites from representation in the federal Assembly. One of the objections of the Cape ministry to Carnarvon's scheme was to its retrograde and illiberal nature.3 Goodfellow's own conclusion, following Robinson and Gallagher,4 is that Carnarvon's interest in South Africa arose essentially from its strategic position on the route to India, and that confederation was intended to ensure continued
