World Expos are frequently portrayed as direct descendants of trade fairs. It is true that trade promotion is one of the reasons behind the creation of World Expos, and that trade fairs and World Expos bear some similarities, but there is a disconnection between the evolution of trade fairs and the development of three essential characteristics of World Expos:

  1. World Expos are fundamentally non-commercial

  2. World Expos do not happen periodically in the same place

  3. Official participants in World Expos are not businesses, but governments of other countries, invited exclusively through diplomatic channels


Many authors skip a process of over 55 years that shaped these and other core characteristics of World Expos. In his book Ephemeral Vistas, Paul Greenhalgh explains in detail how World Expos originated and how they developed as a concept. If you are interested, I recommend a newer version of the book, available under the title Fair World.


In this 55-year-long period, exhibition organizers in France and the United Kingdom fostered innovation through education for the masses, experimented with the duration and extension of the event, and moved towards an international projection of an official nature. All these elements came together for the first time in London in 1851, at the Great Exhibition of the Works of Industry of All Nations. On May 1, 1851, a tradition of World Expos was born that has been alive for 170 years.

National Exhibitions in France

In the aftermath of the French Revolution, France feared having to depend commercially on the British Empire, whose products had been aggressively entering the domestic market since 1789.

At the end of the 18th century, the Marquis d'Avèze and François de Neufchâteau materialized the idea of hosting a national exhibition in France that, in addition to promoting national products, sent a message of self-confidence to the French industry. An exhibition was held in Paris in 1797, "in the hope that a good showing would not only dispose of stockpiled goods but also show the French public that their industry was still intact and capable of competing internationally." (Greenhalgh, 2011 p. 15)

In 1798, France organized a second exhibition, this time in a temporary building designed specifically for the event on the Champs de Mars, in Paris. Selling remained a central objective, but a new element, aimed primarily at French manufacturers, was added to the message: They were encouraged to work harder, to consider the importance of their products' presentation, and to introduce more aggressive marketing techniques.

France organized eleven national exhibitions between 1797 and 1849, which in addition to progressively increasing in size and attendance, also disseminated the message beyond its borders and influenced perceptions of France abroad.

National exhibitions in the United Kingdom

The United Kingdom held similar events, which although smaller in scale, were more openly oriented toward education. The Society of Arts fostered a positive impact of the arts on trade and industry. In 1760, this institution carried out an exhibition which Kenneth Luckhurst referred to as "the first fully organized public exhibition of this country". In this exhibition and those that followed, art was expected to have a practical use and was often shown under the title of "inventions". At the center of the Arts Society's exhibition policy, there was a severe insistence on making everything be done for a useful purpose: art should improve industry, and consequently, trade.

From 1837, the Mechanics Institutes followed the example of the Society of Arts and organized art and industry exhibitions in numerous cities around the United Kingdom. The purpose of these exhibitions was philanthropic, rather than economic, with the main objective of stimulating the consciousness of the working class and promoting an industrial culture in general.

Education as a central component of exhibitions

France and the United Kingdom gave national exhibitions - which later became international - their educational character from two different perspectives. France needed to show techniques to its industry and give it confidence to strengthen it nationally and internationally. It turned exhibitions into a national policy. The United Kingdom was not engaged in selling, but in developing technology. Therefore, its national exhibitions promoted experimentation and creativity.

For both countries, the principle of the exhibition "would be a mechanism to enhance trade, for the promotion of new technologies, for the education of the ignorant middle classes and for the elaboration of a political stance".

The educational approach changed little during the first half of the 19th century. The major changes occurred mainly in duration and extension: French national exhibitions went from a duration of four days in 1797, to six months in 1849; and from a participation of 220 exhibitors in 1801, to 4'532 exhibitors in 1849.

From national to international exhibitions

Although the first World Expo was held in London, Paul Greenhalgh (p. 23) notes that "the idea of making the exhibitions international, evolved not in Britain but in France, some time before 1851."

[...] it would be interesting for [France] in general, to be made acquainted with the degree of advancement towards perfection attained by our neighbors in those manufactures in which we so often come into competition with foreign markets.

Louis Buffet, Minister of Agriculture and Commerce, France. (In Wyatt. p. 34)

In 1834, Jacques Boucher de Perthes recommended French national exhibitions to become international, with the idea that domestic manufacturers learned from foreign producers. In 1849, the Ministry of Agriculture and Commerce of France presented the issue for the second time.

However, both proposals received widespread disapproval throughout France because of generalized distrust of the effects free trade would have on the national economy.


Henry Cole, the main organizer of the Exhibition of 1851 in the United Kingdom, after having heard the idea when visiting the French exhibition in 1849, took it up again and presented it to Prince Albert, President of the Royal Commission for the Exposition of 1851.

I asked [Prince Albert] if he had considered if the exhibition should be a national or an international exhibition. The French had discussed if their own exhibition should be international, and preferred that it be national only. The Prince reflected for a minute, and then said, "It must embrace foreign production," to use his words, and added emphatically, "International, certainly."

Henry Cole (Greenhalgh, p. 25)

Queen Victoria invited, through diplomatic means, other countries to participate in the Great Exhibition of the Works of Industry of All Nations. Twenty-five countries were represented at the Expo, which received more than 6 million visits between May 1 and October 11, 1851.


This is how World Expos came to develop three of their main characteristics:

  1. their purpose is educational and cannot be fundamentally commercial

  2. they do not happen periodically in the same place

  3. official participants are countries invited exclusively through diplomatic channels
