In the particular and peculiar case of the Booker Prize, regarded as the most prestigious literary award in the United Kingdom (as measured by economic value to the author and publisher, and total audience for the awards announcement), the cultural and economic valences of literary prizes collide with the imperial history of Britain, and its after-empire relationships to its former colonies. From its beginnings, the Booker prize has never been simply a British prize for writers in the United Kingdom. The Booker’s reach into the Commonwealth of Nations, a loose cultural and economic alliance of the United Kingdom and former British colonies, challenges the very constitution of the category of post-imperial British literature. With a history of winners from India, South Africa, New Zealand, and Nigeria, among many other former British colonies, the Booker presents itself as a value arbitrating mechanism for a majority of the English-speaking world. Indeed, the Booker has maintained a reputation for bringing writers from postcolonial nations to the attention of a British audience increasingly hungry for a global, cosmopolitan literature, especially one easily available via the lingua franca of English. Whether and how the prize winners avoid the twin colonial pitfalls of ownership by and debt to an English patron is the subject of a great deal of criticism on the Booker, and to understand the prize as a gatekeeper and tastemaker for the loose, baggy canon of British or even global Anglophone literature, there must be a reckoning with the history of the prize, its multiplication into several prizes under one umbrella category, and the form and substance of the novels that have taken the prize since 1969.
