[1] In 1893 Grave wrote La société mourante et l'anarchie,[1] prefaced by Octave Mirbeau, for which he was sentenced to two years in prison.
Mirbeau, like Élisée Reclus, Paul Adam, and Bernard Lazare had testified on Grave's behalf, but to no avail.
The trial only popularised the book, which was rapidly translated into German, Spanish, Portuguese, Italian and Yiddish.
From 1895 to 1922 Grave was the editor of Les Temps nouveaux,[1] which was influential in literary and artistic circles of the time.
In 1914 Grave joined Kropotkin in England, and incurred the wrath of anti-war anarchists by signing the Manifesto of the Sixteen, which supported the allies during World War I.
