The U.S. Civil War is closely related to the podcast episodes, as they both touch on the historical efforts to establish ethical guidelines and international legal mechanisms for warfare.

The episode on the 'Rules of War' discusses how the Lieber Code, developed during the U.S. Civil War, laid the groundwork for subsequent international legal efforts to prosecute war crimes. Similarly, the episode on Robert's Rules of Order mentions the Civil War era and how Robert's decision to remain in the Union army despite his Southern roots influenced his work.

The U.S. Civil War was a pivotal event that shaped the development of international law and the codification of the rules of war, as explored in these podcast episodes.
