Under the headings of “Rechtssoziologie” in Germany and “sociolegal studies” in the UK, scholarly traditions have developed that relate law to its social environment. This Article identifies key stages in the development the subject took in both countries and the directions of travel. Comparable milestones were passed, and directions were taken in Germany and the UK. This includes the institutionalization of the subject along the lines of programmatic texts; becoming part of university education; and the establishment of research institutes, academic associations, and specialized journals. The development tells us something beyond sociology of law or sociolegal studies, namely about the relation of law and sociology, the parent disciplines themselves, as well as about academic studies and professional and institutional practice. However, in contrast to the UK, there is still more of a distance between the sociology of law and jurisprudence in Germany.
