Chris Braithwaite (aka "Chris Jones") was a black Barbadian seafarer who became a leading organiser of colonial seafarers in inter-war Britain. He played a critical role in the Pan-Africanist and wider anti-colonial movement alongside figures such as C.L.R. James and George Padmore. Christian Hogsbjerg recovers Braithwaite's long overlooked life as a black radical and political trade-unionist, and suggests his determined struggle for working class unity in the face of racism and austerity retains relevance for us today.
