Ligali is a Pan-African human rights organisation that challenges the misrepresentation of African people, culture and history in the British media. It produced various responses to promote the African perspective of the 2007 bicentenary, including their 'Declaration of Protest to the 2007 Commemoration' expressing dissatisfaction with much of the terminology and focus of the 'official' commemorations. Their particular focus was on the ‘Maafa’, derived from the Kiswahili word meaning ‘great disaster’, and referring to the ongoing impact of enslavement and colonialism for African peoples. The publication ‘Addressing Maafa denial and slavery apologists’ was a guide to promoting the truth about the Maafa from an Africentric position.

‘Maafa: Truth 2007’ is a documentary film directed by the Ligali founder, Toyin Agbetu, and produced by Ligali’s then head of media affairs, emma pierre. The film confronts some of the myths about British slavery, featuring contributions from community activists, project workers, teachers and the African British business community. The film was screened at various events, including African Remembrance Day at Hackney Town Hall in 2006. Ligali’s ‘Freedom Fighter’ stamps were designed by Emma Pierre-Joseph as a response to the Royal Mail’s publication of six stamps to mark the bicentenary. ‘The Walk’ is a documentary record of Toyin Agbetu’s protests at the service at Westminster Abbey to mark the bicentenary on 27 March 2007.

In 2007, Royal Mail marked the bicentenary of the abolition of the British slave trade with a series of stamps. Designed by Howard Brown, the First Class stamp showed Olaudah Equiano. Other stamps in the collection featured the abolitionists William Wilberforce, Granville Sharp, Thomas Clarkson, Hannah More and Ignatius Sancho.
