 In 1907, the International Anarchist Congress of Amsterdam gathered delegates from 14 different countries, among which important figures of the anarchist movement, including Errico Malatesta, Pierre Monatte, Luigi Fabbri, Benoît Broutchoux, Emma Goldman, Rudolf Rocker, and Christiaan Cornelissen. Various themes were treated during the Congress, in particular concerning the organisation of the anarchist movement, popular education issues, the general strike or antimilitarism. A central debate concerned the relation between anarchism and syndicalism (or trade unionism). Malatesta and Monatte were in particular disagreement themselves on this issue, as the latter thought that syndicalism was revolutionary and would create the conditions of a social revolution, while Malatesta did not consider syndicalism by itself sufficient. He thought that the trade-union movement was reformist and even conservative, citing as essentially bourgeois and anti-worker the phenomenon of professional union officials. Malatesta warned that the syndicalists aims were in perpetuating syndicalism itself, whereas anarchists must always have anarchy as their end and consequently refrain from committing to any particular method of achieving it.
