This study of a specific instance of culture contact, that provided by the situation of West African students in Britain, is limited to a discussion and analysis of their association in the West African Students' Union. The fact of common geographical origin partly explains the formation of such a Union, for the same reason as United States, Canadian, South African, and other large groups of students living in Britain have become so organized. But this would ignore the situation of colour prejudice facing coloured students in Britain, and also their colonial status in relation to Britain. Because of this determining characteristic of being an association of coloured colonial students, the West African Students' Union has developed, throughout its history, certain features not normally found among students' unions, and which are reminiscent of ‘protest movements’. The analysis which is presented here seeks to determine the reasons why West African students organized themselves into the West African Students' Union from 1926 onwards. It is unfortunately not possible to do more here than touch briefly upon the major changes which took place during that time, but as most of the data here presented have not hitherto been published, enough details have been included to give an idea of the manner in which members of the West African Students' Union responded to the situation of culture contact. The paper is divided into two parts: first, an historical account of the type of ideas held by the members of the Union; and, secondly, a discussion of the reasons why West African students join the Union.
