With extraordinary productivity and immense innovative intuition, historian Jurgen Sarnowsky, professor of medieval history in Hamburg, has decisively impacted historical research. Time and again, he has forged new paths and opened up new fields of historical inquiry in regional, global, and digital spheres. The articles by friends, students, and academic companions assembled in this volume in Sarnowsky's honor enter into a dialogue with his works and offer illuminating new insights into central areas of his oeuvre. They encompass the North and the Hanseatic League, the Mediterranean region, the Teutonic Order, and digital humanities, as well as travel and distance.
