English summary: The first German conference for Young Scholars of Private International Law, which was held at the University of Bonn in spring 2017, provides the topical content for this volume. Ever since Savigny, conflict of laws rules have traditionally been perceived as unbiased or value-neutral in Central Europe because they are only supposed to coordinate the applicable substantive law. However, during the second half of the past century the opinion that conflict of laws rules may also strengthen or prevent certain results of substantive law has become prevalent. The articles are dedicated to the various possibilities and aspects of this interaction between private international law and politics as well as to the advantages and disadvantages of this interplay. Traditional policy instruments of private international and international procedural law are discussed, such as the public policy exception and international mandatory rules ( loi de police). The focus is on topics such as human rights violations, immission and data protection, and international economic sanctions. Furthermore, more modern tendencies, such as the use of private international law by the EU and the European Court of Justice, are also discussed. German description: Dieser Tagungsband beinhaltet die Beitrage, die aus der ersten Tagung des IPR-Nachwuchses in Bonn im Fruhjahr 2017 hervorgegangen sind. Die Beitrage widmen sich den unterschiedlichen Moglichkeiten und Aspekten des Zusammenspiels von politischen Zielsetzungen mit dem Kollisionsrecht. Es wird auf 'traditionelle' politische Elemente des Internationalen Privat- und Verfahrensrechts eingegangen, insbesondere den verfahrens- und kollisionsrechtlichen ordre public sowie Eingriffsnormen bezogen auf Thematiken wie Menschenrechtsverletzungen, Immissions- und Datenschutz und Wirtschaftssanktionen, aber auch auf 'moderne' Tendenzen wie die Politisierung des IPR/IZVR durch die EU und den EuGH.
