Historical research into the petite bourgeoisie in Belgium did not begin until quite a bit later than it did abroad. On closer inspection, that was no bad thing. Because of the late start by Belgian historians, they were more open-minded and less inclined towards the research into the roots of Fascism which was largely based on pre-war sociological theories. Beginning in 1980, pioneering research was carried out at the Université Libre de Bruxelles – for the most part on the period before the First World War. The research group under the direction of Ginette Kurgan-van Hentenryk systematically analysed several important series of sources and produced interesting detailed studies. In 1993 Serge Jaumain published a comprehensive study on Belgian retail trade in the period from 1880 to 1914.
