The article illustrates the very different developments of the subregions making up the Greater Region, but also the similarities (e.g. guest worker migration in the 1960s and 70s in the Greater Region, ethnic Germans who migrated to Germany in recent decades or American forces in Rhineland-Palatinate. The article looks in depth at each subregion, sets out the specificities of the regions and analyses the reasons behind them. The development of the subregions is also examined in the context of their historical and economic development and the removal of the borders under the Schengen Agreement and the emergence of simplified cross-border migration (e.g. also atypical cross-border commuters) within the Greater Region. The different approaches to integration are also described.
