Attempts to promote closer relations among the states of Southern Africa in the third quarter of the nineteenth century were thwartedinter aliaby intense rivalry between the two British coastal colonies, Natal and the Cape. The sources of this struggle have usually been sought in the strenuous efforts made by each colony to monopolize the transit trade to the interior and in their attempts to develop in the hinterland those markets which the metropolitan countries of Europe did not offer them. But Natal's geographical situation tempted her also to seek economic salvation in the Indian Ocean. At various stages of the colony's history, Natal's businessmen and politicians showed considerable interest in the commercial potential of the region, in its labour resources, and in the creation of steamship and telegraphic lines of communication through the Ocean to the East and Europe. These, it was believed, would not only be of economic advantage to Natal but would also afford her greater independence in many ways from the older-established and far wealthier sister colony. Yet these conflicting ambitions and policies—particularly the commercial connexions of each colony with Mauritius—did much to exacerbate relations between them. Both in 1866 and in 1876, proposals merely for a free trade treaty in each other's produce were easily defeated. The divergence of interests and sympathies between the two colonies, so evident at the National Convention in 1909, stemmed from a great variety of sources—political, economic, geographical and others. Their rivalry had a long history, but was seldom so pronounced as in the earliest years of their relationship.
