There has been a German presence at World Expos since the first – the 1851 Great Exhibition in London. As an active participant in Expos, Germany was one of the 31 countries that signed the Paris Convention of 1928 that created the BIE. Germany’s involvement in Expos has continued ever since with regular participation in Expos and the organisation of World Expo 2000 in Hannover. Germany has also been host to two Specialised Expos (Expo 1957 in Berlin and Expo 1965 Munich), and five Category A1 International Horticultural Exhibitions.
