El único y su propiedad
Stirner was a philosopher whose "name appears with familiar regularity in historically-orientated surveys of anarchist thought as one of the earliest and best-known exponents of individualist anarchism". In 1844, his "The Ego and Its Own" ("Der Einzige und sein Eigentum" which may literally be translated as "The Unique Individual and Its Property") was published and it is considered to be "a founding text in the tradition of individualist anarchism".
