Several factors account for the emergence of the migrant fiction tradition that underscores the imperative of mobility in African literature. As a corpus, African literature is generally viewed as a responsible art through which writers relate their socio-historical experiences and show their inclinations towards social commitment. Migration is a human phenomenon with social, economic and cultural significance. In other words, the theme of migration in African letters is a response to the socio-historical dynamics of the twenty-first century. Aside from migration's multidisciplinary relevance, it has remained a strong trope in the African creative imagination. Fictional narratives of migration appeal to the sensibilities of writers (in this case, Nigerian writers), because of their potential to represent the experience of living in exile. In fact, exilic consciousness remains a vibrant theme in African literature due to the ravages experienced by most post-independence African states. It is therefore imperative that African fiction captures contemporary realities of migration in the emerging corpus of third-generation African writers.

The continued exploration of migrant aesthetics and representations of migratory experiences in post-colonial African literature has been a response to the dictates of the twentieth century, where writers cross boundaries and become ‘cultural travellers’ whose works portray experiences in diverse settings. This pot-pourri of cultural experiences enables them to fashion a distinct character of ‘cosmopolitanism’. This is akin to ‘Afropolitanism’, which seeks to connect Africa to ‘mainstream’ intellectual knowledge production and dissemination. In evaluating this trend, Boehmer writes:

It should be pointed out that the migrant tradition in African literary hybrid consciousness necessarily has political and economic ancestries. The relationship between the colonizer and the colonized, for instance, has encouraged migration and/or constant mobility among African writers. In most African societies, the former colonial powers continue to wield such diverse influences that there is a historical pull for refuge in Western capitals.
