The Booker International Prize was initially awarded every two years in recognition of the work of an author of any nationality whose work is available in English. The first prize was awarded in 2005. There was also a separate prize for translation into English, the winner of which is chosen by the winning author.
In July 2015 it was announced that the Prize was to join with the Independent Foreign Fiction Prize. The new prize is awarded annually for a single book, translated into English and published in the UK, and the prize money is split equally between the author and translator.
