Leeds-born businessman Richard Oastler was a leading figure in the 19th century campaign to end child slavery in the factories and mills of Yorkshire. The University of Huddersfield Archives, West Yorkshire Archives, Huddersfield Local History Library and Kirklees Museums and Galleries hold significant sources relating to the Huddersfield centred campaign against 'Yorkshire Slavery'. This project devised an exhibition ('The Past and Present of the Slave Trade') and heritage trail, and ran workshops for school children, local societies and youth theatres. A conference was held, and the University of Huddersfield Press later published John A. Hargreaves and E. A. Hilary Haigh, 'Slavery in Yorkshire: Richard Oastler and the campaign against child labour in the Industrial Revolution' (2012).
