Illegalism was an anarchist practice that developed primarily in France, Italy, Belgium and Switzerland during the early 1900s that found justification in Stirner's philosophy. The illegalists openly embraced criminality as a lifestyle. Illegalists usually did not seek moral basis for their actions, recognizing only the reality of "might" rather than "right". For the most part, illegal acts were done simply to satisfy personal desires and needs, not for some greater ideal, although some committed crimes as a form of propaganda of the deed. Illegalism first rose to prominence among a generation of Europeans inspired by the unrest of the 1890s, during which Ravachol, Émile Henry, Auguste Vaillant and Sante Geronimo Caserio committed daring crimes in the name of anarchism in what is known as propaganda of the deed. The French Bonnot Gang were the most famous group to embrace illegalism. The illegalists broke from anarchists like Clément Duval and Marius Jacob who justified theft with a theory of "la reprise individuelle" (). Instead, the illegalists argued that their actions required no moral basis as illegal acts were performed not in the name of a higher ideal, but in pursuit of one's own desires. As a reaction to this, French anarchist communists attempted to distance themselves from illegalism and anarchist individualism as a whole. In August 1913, the Fédération Communiste-Anarchistes (FCA) condemned individualism as bourgeois and more in keeping with capitalism than communism. An article believed to have been written by Peter Kropotkin in the British anarchist paper "Freedom" argued: "Simple-minded young comrades were often led away by the illegalists' apparent anarchist logic; outsiders simply felt disgusted with anarchist ideas and definitely stopped their ears to any propaganda". Some American individualist anarchists such as Benjamin Tucker abandoned natural rights positions and converted to Max Stirner's egoist anarchism. Rejecting the idea of moral rights, Tucker said that there were only two rights, "the right of might" and "the right of contract". He also said after converting to egoist individualism: "In times past...it was my habit to talk glibly of the right of man to land. It was a bad habit, and I long ago sloughed it off...Man's only right to land is his might over it". In adopting Stirnerite egoism, Tucker rejected natural rights which had long been considered the foundation of his beliefs. This rejection galvanized the movement into fierce debates, with the natural rights proponents accusing the egoists of destroying individualist anarchism itself.
