The theses dealt with various areas, the Bolshevik attitude to the First World War, their attitude to the Provisional Government, and how Russia should be governed in the future and the future of the Bolsheviks.
Particular measures proposed by Lenin included no co-operation with the "bourgeois" Provisional Government; opposition to the war on the grounds that it was a war fought in bourgeois interests by bourgeois governments; and the abolition of the police, army and state bureaucracy which he argued held up the interests of Russia's ruling bourgeosie. Lenin also argued against parliamentary democracy and called for workers control of the state through the system of soviets.
In the theses Lenin also argued that the time had come for the Bolsheviks to consider changing their name to disassociate them from mainstream European social-democracy as he felt this term was devalued by many leading social-democrats supporting their respective country's participation in the war. This was an argument he first developed in his 1915 pamphlet Socialism and War where he called the pro-war social-democrats Social-Chauvinists.
Much of the arguments laid out by Lenin in his theses were aimed directly at the Bolsheviks themselves as much as the wider population. After the events of the February revolution returning Bolshevik leaders from exile such as Josef Stalin and Lev Kamenev were arguing a much more moderate line, that Russian involvement in the war could be justified and that there should be co-operation with the liberals. However, Lenin's arguments reflected those made by the leading Bolsheviks in Petrograd at the time of the February events, such as Alexander Shlyapnikov.
Lenin succeeded in persuading the Bolsheviks of his arguments as laid out in the April Theses and they provided much of the ideological groundwork for the events leading up to their ascendency to power in the October Revolution.
Document: I did not arrive in Petrograd until the night of April 3, and therefore at the meeting on April 4 I could, of course, deliver the report on the tasks of the revolutionary proletariat only on my own behalf, and with reservations as to insufficient preparation.
The only thing I could do to make things easier for myself -- and for honest opponents -- was to prepare the theses in writing. I read them out, and gave the text to Comrade Tsereteli. I read them twice very slowly; first at a meeting of Bolsheviks and then at a meeting of both Bolsheviks and Mensheviks.
I publish these personal theses of mine with only the briefest explanatory notes, which were developed in far greater detail in the report.
THESES
1. In our attitude to the war, which under the new government of Lvov and Co. unquestionably remains on Russia’s part a predatory imperialist war owing to the capitalist nature of that government, not the slightest concession to “revolutionary defencism” is permissible.
The class-conscious proletariat can give its consent to a revolutionary war, which would really justify revolutionary defencism, only on condition: (a) that the power pass to the proletariat and the poorest sections of the peasants aligned with the proletariat; (b) that all annexations be renounced in deed and not only in word; (c) that a complete break be effected in actual fact with all capitalist interests.
In view of the undoubted honesty of those broad sections of the mass believers in revolutionary defencism who accept the war only as a necessity, and not as a means of conquest, in view of the fact that they are being deceived by the bourgeoisie, it is necessary with particular thoroughness, persistence and patience to explain their error to them, to explain the inseparable connection existing between capital and the imperialist war, and to prove that without overthrowing capital it is impossible to end the war by a truly democratic peace, a peace not imposed by violence.
The most widespread campaign for this view must be organised in the army at the front.
Fraternisation.
2. The specific feature of the present situation in Russia is that the country is passing from the first stage of the revolution - which, owing to the insufficient class-consciousness and organisation of the proletariat, placed power in the hands of the bourgeoisie - to its second stage, which must place power in the hands of the proletariat and the poorest sections of the peasants.
This transition is characterised, on the one hand, by a maximum of legally recognised rights (Russia is now the freest of all the belligerent countries in the world); on the other, by the absence of violence towards the masses, and, finally, by their unreasoning trust in the government of capitalists, those worst enemies of peace and socialism.
This peculiar situation demands of us an ability to adapt ourselves to the special conditions of Party work among unprecedentedly large masses of proletarians who have just awakened to political life.
3. No support for the Provisional Government; the utter falsity of all its promises should be made clear, particularly of those relating to the renunciation of annexations. Exposure in place of the impermissible, illusion-breeding “demand” that this government, a government of capitalists, should cease to be an imperialist government.
4. Recognition of the fact that in most of the Soviets of Workers Deputies our Party is in a minority, so far a small minority, as against a bloc of all the petit-bourgeois opportunist elements, from the Popular Socialists and the Socialist-Revolutionaries down to the Organising Committee (Chkheidze, Tsereteli, etc.), Steklov, etc., etc., who have yielded to the influence of the bourgeoisie and spread that influence among the proletariat.
The masses must be made to see that the Soviets of Workers Deputies are the only possible form of revolutionary government, and that therefore our task is, and as long as this government yields to the influence of the bourgeoisie, to present a patient, systematic, and persistent explanation of the errors of their tactics, an explanation especially adapted to the practical needs of the masses.
As long as we are in the minority we carry on the work of criticising and exposing errors and at the same time we preach the necessity of transferring the entire state power to the Soviets of Workers Deputies, so that people may overcome their mistakes by experience.
5. Not a parliamentary republic - to return to a parliamentary republic from the Soviets of Workers' Deputies would be a retrograde step - but a republic of Soviets of Workers', Agricultural Labourers' and Peasants' Deputies throughout the country, from top to bottom.
Abolition of the police, the army and the bureaucracy. i.e. the standing army to be replaced by the arming of the whole people.
The salaries of all officials, all of whom are elective and displaceable at any time, not to exceed the average wage of a competent worker.
6. The weight of emphasis in the agrarian programme to be shifted to the Soviets of Agricultural Labourers' Deputies.
Confiscation of all landed estates.
Nationalisation of all lands in the country, the land to be disposed of by the local Soviets of Agricultural Labourers' and Peasants' Deputies. The organisation of separate Soviets of Deputies of Poor Peasants. The setting up of a model farm on each of the large estates (ranging in size from 100 to 300 dessiatines, according to local and other conditions, and to the decisions of the local bodies) under the control of the Soviets of Agricultural Labourers' Deputies and for the public account.
7. The immediate amalgamation of all banks in the country into a single national bank, and the institution of control over it by the Soviet of Workers' Deputies.
8. It is not our immediate task to “introduce” socialism, but only to bring social production and the distribution of products at once under the control of the Soviets of Workers Deputies.
9. Party tasks: (a) Immediate convocation of a Party Congress; (b) Alteration of the Party Program, mainly (1) on the question of imperialism and the imperialist war; (2) On our attitude towards the state and our demand for a “common state”. (3) Amendment of our out-of-date minimum program. (c) Change our name, we must call ourselves The Communist Party.
10. A new International.
