The UIB was officially started in 1931, in Budapest, by eleven countries
At the end of the 1st World War (1914-1918), contacts were started among Bakery representatives from some European countries, concerning, in particular, labour conditions (working hours, vocational training, salaries), as well as economic aspects of the profession, referring to the new International Labour Organization and Health Organization, both created in Geneva, in 1919, within the framework of the League of Nations. On the initiative of the Italian engineer Mr. LURASCHI, who was the promoter of what would become UIB in 1931, four encounters were held in Leipzig (1922), Brussels (1924), Rome (1929) and Kiel (1930), all of them coinciding with Professional Trade Fairs held in these cities.
