This article examines the work of Lancaster Black History Group (LBHG), a community history collective that was formed in the wake of the 2020 Black Lives Matter protests with the aim of
“fighting racism through education.” It foregrounds the radical political roots of Black British History (BBH), a public history movement concerned with recovering hidden histories in support
of grassroots struggles for racial justice. It details the vibrant exchange between grassroots antiracism, community arts and education, and historical scholarship that characterises BBH. It
then explores how LBHG developed this approach by employing participatory research methods to reconstruct the historical ties of a majority-white Northern English city to Atlantic slavery,
colonialism and industrial capitalism. In conclusion, it argues that durational forms of anti-racist education can help nurture communities of resistance against the ultranationalist xenophobia
of the current political moment.
