THE HAGUE AND GENEVA CONVENTIONS
The Hague Conventions of 1899 and 1907 were the first multilateral treaties that addressed the conduct of warfare and were largely based on the Lieber Code, which was signed and issued by US President Abraham Lincoln to the Union Forces of the United States in April 1863, during the American Civil War. The Lieber Code was the first official comprehensive codified law that set out regulations for behavior in times of martial law; protection of civilians and civilian property and punishment of transgression; deserters, prisoners of war, hostages, and pillaging; partisans; spies; truces and prisoner exchange; parole of former rebel troops; the conditions of any armistice, and respect for human life; assassination and murder of soldiers or citizens in hostile territory; and the status of individuals engaged in a state of civil war against the government.
Provisions concerning the treatment of prisoners of war are contained in the Hague Regulations of 1899 and 1907. In the course of World War I they revealed several deficiencies as well as a lack of precision. Such defects were partly overcome by special agreements made between belligerents in Berne in 1917 and 1918. In 1921, the International Red Cross Conference held at Geneva, expressed the wish that a special convention on the treatment of prisoners of war be adopted.
The International Committee of the Red Cross drew up a draft convention which was submitted to the Diplomatic Conference convened at Geneva in 1929. The Convention does not replace but only completes the provisions of the Hague regulations. The most important innovations consisted in the prohibition of reprisals and collective penalties, the organization of prisoners work, the designation,by the prisoners, of representatives, and the control exercised by protecting Powers L.C.
The 1929 Convention relative to the Treatment of Prisoners of War was replaced by the third Geneva Convention of August 1949.
