Despite heritage sites displaying the history of antislavery across the United Kingdom (UK), the custodians of public history linked to Britain’s slavery past remain predominantly white. Though attempts to diversify the workforce are gathering pace, the unrepresentativeness of the sector is one of many systemic barriers to making heritage more inclusive ahead of a decade of anniversaries to slavery in the 2030s. The sector appears to only ‘listen’ to global majority voices through events like Black History Month or on select anniversaries linked to the memory of British antislavery. Drawing on a programme of joint work between Hull Museums, the University of Hull and a newly formed Wilberforce House Museum Advisory Board, this chapter explores strategies developed in Kingston upon Hull for reducing such inequalities through co-production led and guided by global majority people living in the city. Systemic barriers in the heritage sector need dismantling, but co-production with global majority communities can be one tool for driving much-needed inclusive practice.
