In this study, the author uses Daase’s concept of extended security to analyse the main line of the Habsburg monarchy’s territorial stabilisation between 1815 and 1820 in the context of preserving the status quo and preventing the outbreak of new wars and revolutions in Europe. Using the example of the provinces of Moravia and Silesia, it then specifically looks at the issues of establishing a secret political police, detecting and monitoring dangerous persons and last but not least investigating public opinion before the Congress of Troppau in 1820.
