During this decade, no less than 15 international exhibitions were arranged. After the Second World War, many countries wanted to work together in international organisations to avoid major new wars and facilitate economic development. In 1946, for example, the United Nations was formed to work for peace and security. The purpose of these international exhibitions was usually to strengthen relations and cultural exchanges between the countries, which is why each country's embassy was involved in the exhibition process, usually with the king or head of state as the supreme patron. The texts in Liljevalch's exhibition catalogues from this time were often explicitly political with the hope of good relations and trade relations.
