A colonial exhibition was a type of international exhibition intended to boost trade and bolster popular support for the various colonial empires during the New Imperialism period, which started in the 1880s with the scramble for Africa.
The British Empire Exhibition of 1924–5, held at Wembley Park in north-west London, ranked among these expositions, but perhaps the most notable was the rather successful 1931 Paris Colonial Exposition, which lasted six months and sold 33 million tickets. Paris's Colonial Exhibition debuted on 6 May 1931, and encompassed 110 hectares of the Bois de Vincennes. The exhibition included dozens of temporary museums and façades representing the various colonies of the European nations, as well as several permanent buildings. Among these were the Palais de la Porte Dorée, designed by architect Albert Laprode, which then housed the Musée permanent des Colonies, and serves today as the Cité nationale de l'histoire de l'immigration.
An anti-colonial counter-exhibition was held near the 1931 Colonial Exhibition, titled Truth on the Colonies and was organized by the French Communist Party. The first section was dedicated to the crimes made during the colonial conquests, and quoted Albert Londres and André Gide's criticisms of forced labour while the second one made an apology of the Soviets' "nationalities' policy" compared to "imperialist colonialism".
Germany and Portugal also staged colonial exhibitions, as well as Belgium, which had a Foire coloniale as late as 1948. Human zoos were featured in some of these exhibitions, such as in the Parisian 1931 exhibition.
