What is Black Britain? In 2021, award-winning poet Roger Robinson and acclaimed photographer Johny Pitts rented a red Mini Cooper and decided to follow the coast clockwise in search of an answer to this question. Leaving London, they followed the River Thames east towards Tilbury, where the Empire Windrush docked in 1948. Too often, that is where the history told about Black Britain begins and ends - but Robinson and Pitts continued out of London, following the coast clockwise through Margate to Land's End, Bristol to Blackpool, Glasgow to John O'Groats and Scarborough to Southend on Sea. Here, the authors found not only Black British culture long overlooked in official narratives of Britain, but also the history of Empire and transatlantic slavery to which every Briton is tethered.
