Archives are often a site for complicated or contested meanings, with many collections existing directly or indirectly as a result of colonisation. Scholars are coming together to look at how existing archives can be read decolonially, and digitisation is seen as a powerful tool for making these (primarily European) archives available to researchers in Africa & Asia - the continents to which so many of the collections relate.
A useful brief starting point is Christine Megowan's poster
The British Library's Endangered Archives Programme facilitates the digitisation of archives around the world that are in danger of destruction, neglect or physical deterioration, with the aim of capturing "forgotten and still not written histories, often suppressed or marginalised. It gives voice to the voiceless: it opens a dialogue with global humanity’s multiple pasts"
Lord Alport held senior positions in London and Africa in the 1950s, 1960s and 1970s, and his papers contain important material relating to the consequences of end of Empire in Africa (notably Rhodesia/Zimbabwe). In connection with Zimbabwe, The Tony Rich Archive, dealing with the rise of the nationalist movement 1963-1980, is also of interest.
