Der Einzige und sein Eigentum
European individualist anarchism proceeded from the roots laid by William Godwin, Pierre-Joseph Proudhon and Max Stirner. Proudhon was an early pioneer of anarchism as well as of the important individualist anarchist current of mutualism. Stirner became a central figure of individualist anarchism through the publication of his seminal work "The Ego and Its Own" which is considered to be "a founding text in the tradition of individualist anarchism". Another early figure was Anselme Bellegarrigue. Individualist anarchism expanded and diversified through Europe, incorporating influences from North American individualist anarchism.
