This open access book explores the Co-operative College’s distinctive adult educational tradition over the past century as it provided education for co-operative leaders, employees and members in addition to developing a range of wider educational initiatives and ideas internationally. The Co-operative College is a British educational charity established in 1919, founded on co-operative principles. It played a crucial role in co-operative education in the British Empire and subsequently in the independent nations. In doing so, it brought together vocational and liberal education as well as educating members as part of a movement that fostered significant social change. It draws on original archival research at the National Co-operative Archive in Manchester as well as other material at the National Archives, Bishopsgate Institute and the British Library. Furthermore, the rich archives of the National Co-operative Archive allow for the development of a rich visual history of the movement to be explored.
