Fox Bourne became secretary of the
Aborigines Protection Society (APS) on 4 January 1889. He edited its journal, the ''Aborigines' Friend,
and pressed on public attention the need of protecting native races, especially in Africa. One of the first to denounce publicly the cruel treatment of natives in the Congo Free State in 1890, he used all efforts to secure the enforcement of the provisions of the Brussels Convention of 1890 for the protection of the natives in Central Africa. He forcibly stated his views in The Other Side of the Emin Pasha Expedition
(1891) and in Civilisation in Congo Land'' (1903). To his advocacy was largely due the ultimate improvement in native conditions in the
Belgian Congo. At first, the APS, like the Anti-Slavery Society with which it merged in 1909, supported the work of British chartered companies, and believed that nurturing legitimate and more profitable trade would eliminate slave trafficking. By 1894, the APS retracted its support, protesting against the violence in
Mashonaland in 1893 that resulted from the war which the
British South Africa Company had entered into with the
Matabele under
Lobengula. The APS, in contrast with the Anti-Slavery Society, disapproved of the policy of allowing chartered companies to govern colonies, sensing a conflict of interest between maintaining justice and extracting maximum profit. In 1900, Fox Bourne expressed in a policy statement entitled
The Claims of Uncivilised Races that the native had three fundamental rights: to his land, to his rites and institutions, and to an equal share of profits arising from colonisation. These rights should not be taken without his understanding and approval. Colonisation should be for the 'moral advantage' of the colonised more than for the 'material advantage' of the colonising power. Although he failed in his attempts to secure the franchise for natives in the
Transvaal and
Orange River colonies in 1906, his strong protests against the slave traffic in
Angola and the cocoa-growing islands of
São Tomé and Príncipe compelled the Portuguese government to admit the necessity of reform. In a series of six pamphlets (1906–8) on Egyptian affairs he denounced alleged abuses which took place during the
British occupation, and advocated Egyptian
self-government. Fox Bourne's pertinacious patience in investigation and his clearness of exposition gave his views on native questions wide influence. ==Death==
