Philippe Pétain Henri Philippe Benoni Omer Joseph Pétain (24 April 1856 – 23 July 1951), generally known as Philippe Pétain (] ) or Marshal Pétain ("Maréchal Pétain"), was a French general who reached the distinction of Marshal of France, and later served as the Chief of State of Vichy France also known as Nationalist France or the French State "(Chef de l'État Français)", from 1940 to 1944. Pétain, who was 84 years old in 1940, ranks as France's oldest head of state. Today, he is considered the French equivalent to his contemporary Quisling in Norway. Because of his outstanding military leadership in World War I, particularly during the Battle of Verdun, Pétain was viewed as a national hero in France and was not executed. He was sometimes nicknamed "The Lion of Verdun".
Émile Arnaud Émile Arnaud (1864 – 1921) was a French lawyer, notary, and writer noted for his anti-war rhetoric and for coining the term "pacifism". Arnaud founded the "Ligue Internationale de la Paix et de la Liberté" (International League for Peace and Freedom) in 1861 and was elected its first president. In 1901, he codified his beliefs into a treatise entitled the "Code de la Paix", outlining and defining the goals, political positions and methodology of the Peace movement in general. He described this new political movement as "pacifism", setting it up as a counterbalance to the belligerence of emerging political ideologies such as Socialism and Anarchism. He advocated for humanism, for charity and tolerance, for non-violent conflict resolution and for reaching mutually beneficial political solutions through establishing consensus.
