Peoples of European origin face the most serious dangers in their entire history: demographic collapse, the invasion of foreign colonizers and Islam, the degeneration of the European structure, the subordination of American hegemony, the oblivion of cultural roots, etc. In the form of basic texts and, above all, , a fundamental dictionary of 177 keywords, Guillaume Faye, one of the most prolific authors among the European new right, gives a detailed analysis of the situation and proposes a program for the Reconquista and the Revival of Values. The purpose of this work, which touches on many areas of life - politics, economics, geopolitics, demography, biology etc. - to unite, with the help of a combat doctrine, all strong-willed elements who want to create a network of White Resistance, overcoming internal squabbles and superficial differences. Like the “Manifesto of the Communist Party” of Karl Marx in the 19th century for the left, the right-wing manifesto of Guillaume Fay “For what” we are fighting" is intended to become an ideological guide for the forces fighting for the identity of European peoples in the 21st century.
