We invite you to check out the campaign promoted by the Museum Association devoted to Decolonising Museums.
They unreservedly support initiatives to decolonise museums and their collections. From their website: "Decolonisation is not simply the relocation of a statue or an object; it is a long-term process that seeks to recognise the integral role of empire in museums – from their creation to the present day. Decolonisation requires a reappraisal of our institutions and their history and an effort to address colonial structures and approaches to all areas of museum work."
On their website you will find, beyond other things, useful resources (articles, case studies and so on) and a collection of videos exploring decolonial practice.
