The National Portrait Gallery created a new gallery trail to mark the bicentenary, written by Dr Caroline Bressey. The trail highlighted portraits of key individuals, ranging from Elizabeth I to William Wilberforce, linked to the slave trade and its abolition. Portraits included those who invested in the trade, or who owned slaves and supported slavery, as well as images of enslaved people themselves and of people who were prominent in the movement to abolish the trade. The trail ended with a series of contemporary portraits of individuals involved in preventing slavery today. A week of talks, music, film and family activities included a discussion of the painting 'The Anti-Slavery Convention, 1840' by Benjamin Robert Haydon.
