"the legal codes and drafts of the Enlightenment"

The Enlightenment was the eighteenth century era in which Western culture shifted from traditional church and monarchy led authority to an emphasis on science, reason and democracy.  It was not a single, cohesive set of ideas rather than a movement which advocated debate and rhetoric, the scientific process and the freedom of the individual.  The legal procedures of modern Germany evolved from this time via the Bürgerliches Gesetzbuch of the late nineteenth century.

An important Germanic figure who advocated the aims of the Enlightenment was Frederick the Great of Prussia.
