Mr. Henri Coursier, of the Legal Department of the ICRC, published some time ago a study on “Francis Lieber and the Laws of War” in the International Review, together with a French translation of Orders No. 100 relative to the behaviour of the United States Armies in the field (the famous “Lieber Laws”), the object of which was to have the principles of international law applied during the American civil war (1861–1865). These orders which were immediately recognized and appreciated by the principal lawyers of the time, had a great influence on the future of the law of nations, since it can be said that the Hague Regulations, which sprang from the 1899 and 1907 Peace Conferences, were very largely inspired by them, and several provisions of the Geneva Conventions of August 12, 1949, stem from the same source. It was to Lieber that the President of the United States, Abraham Lincoln, appealed to establish this Code which was promulgated in 1863, thus preceding by one year the First Geneva Convention.
