Not sure about Fascism existing in any appreciable form during the end of the feudal period in Western Europe.
Would you mind checking? In France there were the Terrors and Bonaparte; in England, there was the East India Companies; in the Netherlands, there was the conquest of spice and the Banda Massacre; in Germany and Italy, there were militaristic state unifications; and in Spain, there was the Inquisition and the Carlist Wars.
Are these the instances of 'appreciable form of fascist valence' you mean?
