A Code for the Government of Armies in the Field,

"A Code for the Government of Armies in the Field," authored by Francis Lieber in 1863, is a seminal work that significantly contributed to the development of international humanitarian law. Written during the American Civil War, this influential manuscript sought to establish a framework for the conduct of armed forces, emphasizing ethical behavior and the protection of noncombatants. Lieber’s code articulated principles that aimed to balance military necessity with humanity, arguing that even in warfare, certain moral constraints must be upheld. The text lays out rules regarding the treatment of prisoners, the protection of property, and the obligations of military leaders to adhere to ethical standards. Lieber's insights have inspired subsequent legal codes and conventions, notably influencing the Geneva Conventions. This pioneering work serves as a crucial reference for military ethics, reflecting the enduring necessity for humane treatment amid the complexities of warfare. Lieber’s code remains a powerful reminder of the importance of adhering to moral principles in times of conflict.
