Within written history, Europe is rich in post-imperial situations. In the twentieth century the dwindling empires of this century, born during European colonial expansion after Columbus, gave rise to new post-imperial conditions with a global impact. Europe is no exception. On other continents, empires have also emerged and faded away: Latin-America with the Mayas and the Aztecs, and, notably, Asia where the Chinese Empire has disappeared and re-emerged at different historical junctures. On their way down, European empires have produced what could be labelled a post-imperial stress syndrome, very much like a PTSD, producing certain defensive ideological configurations of parochialism, xenophobia and nostalgic illusions, binding them to a past they have left, but are still chained to, mentally and ideologically. The fall or fading away of an empire is not just an event with a precise date, but a process, which, inevitably, shows cracks before it actually happens. Such frictions anticipating a future reality can only be caught by imagination. This article will concentrate on two such imaginative post-imperial prefigurations before the fact is generally recognized, both concerning the dissolution of the British Empire. It can be argued that, with Brexit, Britain is still trying to come to terms with its post-imperial reality. One such prefiguration will be seen through the eyes of the centre, J.M. Forster’s A Passage to India (1924), the other from the periphery, Chinua Achebe’s Things Fall Apart (1958).
