The Wilberforce Institute for the study of Slavery and Emancipation (WISE) was officially opened in Hull in 2006 in anticipation of the city's bicentenary commemorations. The University of Hull research centre specialises in researching the history of slavery, while also examining contemporary slavery and human rights abuses in the present day. The patron of the institute is Archbishop Desmond Tutu and the institute was opened by then President of Ghana, John Agyekum Kufuor. The WISE Humanitarian Wall commemorates historical and contemporary figures in the struggle against slavery, including Olaudah Equiano, Harriet Beecher Stowe and Nelson Mandela.
