This book provides an overview of Martin Luther's (1483-1546) state thinking whose reformation of faith and church provoked important and controversial consequences concerning the understanding of the political order and power. Luther's main work in this field "Von weltlicher Obrigkeit" is imprinted completely in a modern translation. The analysis of his state thinking in the contemporary context of the 16th century is followed by a systematic interpretation as well as a historical sketch. In the different areas "Luther and Machiavelli," "Resistance" and "Natural law" the contributors develop connections and comparisons to other concepts. The two concluding essays engage with the current topicality of Luther's understanding of state.
