The Twenty-one Conditions, officially the Conditions of Admission to the Communist International, are the conditions, most of which were suggested by Vladimir Lenin, to the adhesion of the socialist parties to the Third International (Comintern) created in 1919. The conditions were formally adopted by the Second Congress of the Comintern in 1920.
Content The conditions were:Minutes of Second Congress of the Communist International
1All propaganda and agitation must bear a really communist character and correspond to the programme and decisions of the Communist International. All the party's press organs must be run by reliable communists who have proved their devotion to the cause of the proletariat. The dictatorship of the proletariat must not be treated simply as a current formula learnt off by heart. Propaganda for it must be carried out in such a way that its necessity is comprehensible to every simple worker, every woman worker, every soldier and peasant from the facts of their daily lives, which must be observed systematically by our press and used day by day.
The periodical and other press and all the party’s publishing institutions must be subordinated to the party leadership, regardless of whether, at any given moment, the party as a whole is legal or illegal. The publishing houses must not be allowed to abuse their independence and pursue policies that do not entirely correspond to the policies of the party.
In the columns of the press, at public meetings, in the trades unions, in the co-operatives – wherever the members of the Communist International can gain admittance – it is necessary to brand not only the bourgeoisie but also its helpers, the reformists of every shade, systematically and pitilessly. 2Every organisation that wishes to affiliate to the Communist International must regularly and methodically remove reformists and centrists from every responsible post in the labour movement (party organisations, editorial boards, trades unions, parliamentary factions, co-operatives, local government) and replace them with tested communists, without worrying unduly about the fact that, particularly at first, ordinary workers from the masses will be replacing 'experienced' opportunists. 3In almost every country in Europe and America the class struggle is entering the phase of civil war. Under such conditions the communists can place no trust in bourgeois legality. They have the obligation of setting up a parallel organisational apparatus which, at the decisive moment, can assist the party to do its duty to the revolution. In every country where a state of siege or emergency laws deprive the communists of the opportunity of carrying on all their work legally, it is absolutely necessary to combine legal and illegal activity. 4The duty of propagating communist ideas includes the special obligation of forceful and systematic propaganda in the army. Where this agitation is interrupted by emergency laws it must be continued illegally. Refusal to carry out such work would be tantamount to a betrayal of revolutionary duty and would be incompatible with membership of the Communist International. 5Systematic and methodical agitation is necessary in the countryside. The working class will not be able to win if it does not have the backing of the rural proletariat and at least a part of the poorest peasants, and if it does not secure the neutrality of at least a part of the rest of the rural population through its policies. Communist work in the countryside is taking on enormous importance at the moment. It must be carried out principally with the help of revolutionary communist workers of the town and country who have connections with the countryside. To refuse to carry this work out, or to entrust it to unreliable, semi-reformist hands, is tantamount to renouncing the proletarian revolution. 6Every party that wishes to belong to the Communist International has the obligation to unmask not only open social-patriotism but also the insincerity and hypocrisy of social-pacificism, to show the workers systematically that, without the revolutionary overthrow of capitalism, no international court of arbitration, no agreement on the limitation of armaments, no 'democratic' reorganisation of the League of Nations will be able to prevent new imperialist wars. 7The parties that wish to belong to the Communist International have the obligation of recognising the necessity of a complete break with reformism and 'centrist' politics and of spreading this break among the widest possible circles of their party members. Consistent communist politics are impossible without this.
The Communist International unconditionally and categorically demands the carrying out of this break in the shortest possible time. The Communist International cannot tolerate a situation where notorious opportunists, as represented by Turati, Modigliani, Kautsky, Hilferding, Hillquit, Longuet, MacDonald, etc., have the right to pass as members of the Communist International. This could only lead to the Communist International becoming something very similar to the wreck of the Second International. 8A particularly marked and clear attitude on the question of the colonies and oppressed nations is necessary on the part of the communist parties of those countries whose bourgeoisies are in possession of colonies and oppress other nations. Every party that wishes to belong to the Communist International has the obligation of exposing the dodges of its 'own' imperialists in the colonies, of supporting every liberation movement in the colonies not only in words but in deeds, of demanding that their imperialist compatriots should be thrown out of the colonies, of cultivating in the hearts of the workers in their own country a truly fraternal relationship to the working population in the colonies and to the oppressed nations, and of carrying out systematic propaganda among their own country’s troops against any oppression of colonial peoples. 9Every party that wishes to belong to the Communist International must systematically and persistently develop communist activities within the trades unions, workers’ and works councils, the consumer co-operatives and other mass workers’ organisations. Within these organisations it is necessary to organise communist cells which are to win the trades unions etc. for the cause of communism by incessant and persistent work. In their daily work the cells have the obligation to expose everywhere the treachery of the social patriots and the vacillations of the 'centrists'. The communist cells must be completely subordinated to the party as a whole.10Every party belonging to the Communist International has the obligation to wage a stubborn struggle against the Amsterdam 'International' of yellow trade union organisations. It must expound as forcefully as possible among trades unionists the idea of the necessity of the break with the yellow Amsterdam International. It must support the International Association of Red Trades Unions affiliated to the Communist International, at present in the process of formation, with every means at its disposal.11Parties that wish to belong to the Communist International have the obligation to subject the personal composition of their parliamentary factions to review, to remove all unreliable elements from them and to subordinate these factions to the party leadership, not only in words but also in deeds, by calling on every individual communist member of parliament to subordinate the whole of his activity to the interests of really revolutionary propaganda and agitation.12The parties belonging to the Communist International must be built on the basis of the principle of democratic centralism. In the present epoch of acute civil war the communist party will only be able to fulfil its duty if it is organised in as centralist a manner as possible, if iron discipline reigns within it and if the party centre, sustained by the confidence of the party membership, is endowed with the fullest rights and authority and the most far-reaching powers.13The communist parties of those countries in which the communists can carry out their work legally must from time to time undertake purges (re-registration) of the membership of their party organisations in order to cleanse the party systematically of the petty-bourgeois elements within it.14Every party that wishes to belong to the Communist International has the obligation to give unconditional support to every soviet republic in its struggle against the forces of counter-revolution. The communist parties must carry out clear propaganda to prevent the transport of war materiel to the enemies of the soviet republics. They must also carry out legal or illegal propaganda, etc., with every means at their disposal among troops sent to stifle workers’ republics.15Parties that have still retained their old social democratic programmes have the obligation of changing those programmes as quickly as possible and working out a new communist programme corresponding to the particular conditions in the country and in accordance with the decisions of the Communist International.
