Editing Lieber Code (section)

===International law===
In the late 19th century and in the early 20th century, the parties to the [[Hague Conventions of 1899 and 1907]] used the Lieber Code (General Orders No. 100, April 24, 1863) as a basis for their legislation of the international law of war and the codification (definition and description) of what is a [[war crime]] and of what is a [[crime against humanity]]. In the mid 20th century, in the aftermath of the [[Second World War]] (1 September 1939 – 2 September 1945), at the war-crime [[Nuremberg Trials]] (20 November 1945 – 1 October 1946) and at the [[Tokyo Trials]] (29 April 1946 – 12 November 1948) the jurists determined that, by the year 1939, most governments in the world knew of the existence the [[law of war]], agreed in Switzerland, and thus most governments knew the legal responsibilities of the [[belligerent]] parties, of [[neutral country|neutral countries]], and of the [[refugees]] from the war.<ref>{{harvnb|Witt|2013}}.{{pageno|date=February 2023}}</ref>
