Research on ‘Justice in Relation to Society’ is an expanding domain but is generally lacking a multidimensional approach in the social sciences. Building on the experience and results of a previous IAP project on “Justice & Society” (P6/01) which has covered major gaps in the knowledge about Belgium’s national justice history from a top-down and institutional perspective, the current project extends the scope to tackle the theme of the relationships between Justice and populations from an interdisciplinary, long-term perspective, covering the period from 1795 (end of the Ancien Régime in Belgium) up to the present.
