In consequence of the ever-growing challenges, through migration, ageing, and regressive birth rates, the micro and small communities, have to think about possibilities to handle with these problematical developments. One way to handle these developments would be to think about the possibility of corporation amalgamation. These current master thesis discuss, what are the causes and reasons for amalgamations, how does the implementation work, what are the possibilities for the population to participate due the process of amalgamation and how does a real amalgamation do look like? In the first parts of the thesis there is a theoretical discussion of the topic and after that, an analysis of a case study. These addresses to the voluntary amalgamation in Upper-Austria of Aigen-Schlägl. This part consider with the process of the amalgamation and the hindsight, one year after the amalgamation. This way of retrospective analysis gives the possibility to show the first results of the amalgamation, and the possibility to give to other planed amalgamations recommendations. Nevertheless, in any further amalgamations, the process has to be coordinated and adjusted on the local circumstances in order to achieve the best results.
