In the Disney+ television series, A Thousand Blows, Malachi Kirby plays Hezekiah Moscow, a Jamaican immigrant in London who is part of an underground boxing ring in the 1880s.
The character, like many in the show, is based on a real-life figure. However, as historian David Olusoga recently explained in a comment to the Radio Times, Moscow is typical of many people who have come from the Caribbean or Africa in that we only have a fractured biography in the British historical records. We get flashes of information before he disappears.
In recent years, there have been increasing creative efforts to fill these historical gaps. This suggests there is a willingness, at least in some spheres, to acknowledge the long history of multiculturalism in Britain and to see people of colour in 19th-century histories (see also 2019’s David Copperfield starring Dev Patel and the multicultural cast of Bridgerton).
