German military law has a long history.

The Leipzig war crimes trials were held in 1921 to try alleged German war criminals of the First World War before the German Reichsgericht in Leipzig, as part of the penalties imposed on the German government under the Treaty of Versailles. Twelve people were tried, and the proceedings were widely regarded at the time as a failure. In the longer term, they were seen by some as a significant step toward the introduction of a comprehensive system for the prosecution of international law violations.
