The chapel being built used free labour. British missionaries in Belgian Congo. This image formed part of the Harris Lantern Slide Collection.

Alice Seeley Harris and her husband Reverend John H. Harris were missionaries in the Congo Free State from the late 1890s. Alice produced a collection of images documenting the horrific abuses of the African rubber labourers. Her photographs are considered to be an important development in the history of humanitarian campaigning. The images were used in a number of publications. The Harrises also used the photographs to develop the Congo Atrocity Lantern Lecture which toured Britain and the the USA raising awareness of the issue of colonial abuses under King Leopold II's regime.

A portrait of British abolitionist Edmund Dene Morel (1873-1924). Morel was a shippping clerk for the Liverpool company Elder Dempster which had a shipping contract between Antwerp and Boma. He raised the alarm about exploitative practices when he noticed that ships destined for the Congo Free State were packed with guns, chains and explosives rather than the usual trade good. In response to what he discovered Morel went on to found the Congo Reform Association. He also set up his own newspaper - The West African Mail - which focused on the commercial abuses being committed in the Congo Free State.

The Congo Atrocity Lantern Lecture was devised by the British missionary couple Reverend John Harris and his wife Alice Seeeley Harris. Based on their time spent in the Congo Free state, it combined her atrocity photography with witness statements from a variety of sources. The lecture toured Britain and proved so popular that a standard set of lecture notes was developed so that the talk could be delivered by different speakers. The lecture icluded material designed to promote awareness of the brutal slave labour regime that occurred under King Leopold II. It also included material promoting British missionary activities in the area. The language and the accompanying slides were part of a discourse on the European 'civilising mission' and were used to justify the expansion of the colonial project as well as antislavery sentiment.
