2007 saw a number of different projects taking place at Harewood House in West Yorkshire, home of the Lascelles family. The bicentenary was used as an opportunity to explore the family connections with the transatlantic slave trade and the sugar plantations of the West Indies.

As part of a newly developed Learning Programme, leaflets were produced setting out the family connections to Barbados. 2007 also marked the bicentenary of the Yorkshire election in 1807 contested by William Wilberforce, Henry Lascelles (later 2nd Earl of Harewood) and Lord Milton. Competition between the candidates was fierce, based on issues such as Catholic Emancipation, poverty, workers' rights and abolition of the slave trade.

The Lascelles Slavery Archive was a collaborative project between the Borthwick Institute for Archives and Harewood House Trust to conserve, preserve and make available records relating to slavery from the archives of the Lascelles family of Harewood House, Yorkshire. The project deals with a new discovery of papers relating to the family's fortune based on its estates in the West Indies. Key documents providing evidence for the acquisition of the family's wealth, once thought lost, were found in poor condition during an inventory of Harewood House. The Lascelles Slavery Archive is available through the Borthwick's searchrooms as an online resource, and represents an important section of the larger archive of the Lascelles family held by West Yorkshire Archive Service.

Campaign! Make an Impact was a British Library developed programme that used history to inspire young people into active citizenship. The Bitter Sweet Project involved students from Easingwold School engaging with collections from the British Library, Hull Museums Service and Harewood House. Year 9 students studied the 1807 campaign to abolish the transatlantic slave trade and then created a graphic novel about Harewood House’s links to the sugar trade.

The Sites of Memory project was the first research by English Heritage (now Historic England) to provide an overview for the public of the buildings, memorials and grave sites across England that reflects the role of the slave trade in British history, and resistance to it. The project explored the history of Black people in Britain during the 18th and 19th centuries by exploring the stories behind the historic built environment of local streets, buildings and landmarks. The research (by historians Angelina Osborne and S. I. Martin, on behalf of English Heritage) also identified sites associated with the slave trade and plantation wealth, and with the abolitionists who campaigned for an end to slavery. English Heritage also made recommendations for new listings for historic sites that mark the Black presence.
