First and foremost, the struggle against opportunism which in 1914 definitely developed into social-chauvinism and definitely sided with the bourgeoisie, against the proletariat. Naturally, this was Bolshevism’s principal enemy within the working-class movement. It still remains the principal enemy on an international scale. The Bolsheviks have been devoting the greatest attention to this enemy. This aspect of Bolshevik activities is now fairly well known abroad too.
It was, however, different with Bolshevism’s other enemy within the working-class movement. Little is known in other countries of the fact that Bolshevism took shape, developed and became steeled in the long years of struggle against petty-bourgeois revolutionism, which smacks of anarchism, or borrows something from the latter and, in all essential matters, does not measure up to the conditions and requirements of a consistently proletarian class struggle. Marxist theory has established—and the experience of all European revolutions and revolutionary movements has fully confirmed—that the petty proprietor, the small master (a social type existing on a very extensive and even mass scale in many European countries), who, under capitalism, always suffers oppression and very frequently a most acute and rapid deterioration in his conditions of life, and even ruin, easily goes to revolutionary extremes, but is incapable of perseverance, organisation, discipline and steadfastness. A petty bourgeois driven to frenzy by the horrors of capitalism is a social phenomenon which, like anarchism, is characteristic of all capitalist countries. The instability of such revolutionism, its barrenness, and its tendency to turn rapidly into submission, apathy, phantasms, and even a frenzied infatuation with one bourgeois fad or another—all this is common knowledge. However, a theoretical or abstract recognition of these truths does not at all rid revolutionary parties of old errors, which always crop up at unexpected occasions, in somewhat new forms, in a hitherto unfamiliar garb or surroundings, in an unusual—a more or less unusual—situation.
Anarchism was not infrequently a kind of penalty for the opportunist sins of the working-class movement. The two monstrosities complemented each other. And if in Russia—despite the more petty-bourgeois composition of her population as compared with the other European countries—anarchism’s influence was negligible during the two revolutions (of 1905 and 1917) and the preparations for them, this should no doubt stand partly to the credit of Bolshevism, which has always waged a most ruthless and uncompromising struggle against opportunism. I say "partly", since of still greater importance in weakening anarchism’s influence in Russia was the circumstance that in the past (the seventies of the nineteenth century) it was able to develop inordinately and to reveal its absolute erroneousness, its unfitness to serve the revolutionary class as a guiding theory.
When it came into being in 1903, Bolshevism took over the tradition of a ruthless struggle against petty-bourgeois, semi-anarchist (or dilettante-anarchist) revolutionism, a tradition which had always existed in revolutionary Social-Democracy and had become particularly strong in our country during the years 1900-03, when the foundations for a mass party of the revolutionary proletariat were being laid in Russia. Bolshevism took over and carried on the struggle against a party which, more than any other, expressed the tendencies of petty-bourgeois revolutionism, namely, the "Socialist-Revolutionary" Party, and waged that struggle on three main issues. First, that party, which rejected Marxism, stubbornly refused (or, it might be more correct to say: was unable) to understand the need for a strictly objective appraisal of the class forces and their alignment, before taking any political action. Second, this party considered itself particularly "revolutionary", or "Left", because of its recognition of individual terrorism, assassination—something that we Marxists emphatically rejected. It was, of course, only on grounds of expediency that we rejected individual terrorism, whereas people who were capable of condemning "on principle" the terror of the Great French Revolution, or, in general, the terror employed by a victorious revolutionary party which is besieged by the bourgeoisie of the whole world, were ridiculed and laughed to scorn by Plekhanov in 1900-03, when he was a Marxist and a revolutionary. Third, the "Socialist-Revolutionaries," thought it very "Left" to sneer at the comparatively insignificant opportunist sins of the German Social-Democratic Party, while they themselves imitated the extreme opportunists of that party, for example, on the agrarian question, or on the question of the dictatorship of the proletariat.
History, incidentally, has now confirmed on a vast and world-wide scale the opinion we have always advocated, namely, that German revolutionary Social-Democracy (note that as far back as 1900-03 Plekhanov demanded Bernstein’s expulsion from the Party, and in 1913 the Bolsheviks, always continuing this tradition, exposed Legien’s  baseness, vileness and treachery) came closest to being the party the revolutionary proletariat needs in order to achieve victory. Today, in 1920, after all the ignominious failures and crises of the war period and the early post-war years, it can be plainly seen that, of all the Western parties, the German revolutionary Social-Democrats produced the finest leaders, and recovered and gained new strength more rapidly than the others did. This may be seen in the instances both of the Spartacists and the Left, proletarian wing of the Independent Social-Democratic Party of Germany, which is waging an incessant struggle against the opportunism and spinelessness of the Kautskys, Hilferdings, Ledebours and Crispiens. If we now cast a glance to take in a complete historical period, namely, from the Paris Commune to the first Socialist Soviet Republic, we shall find that Marxism’s attitude to anarchism in general stands out most definitely and unmistakably. In the final analysis, Marxism proved to be correct, and although the anarchists rightly pointed to the opportunist views on the state prevalent among most of the socialist parties, it must be said, first, that this opportunism was connected with the distortion, and even deliberate suppression, of Marx’s views on the state (in my book, The State and Revolution, I pointed out that for thirty-six years, from 1875 to 1911, Bebel withheld a letter by Engels , which very clearly, vividly, bluntly and definitively exposed the opportunism of the current Social-Democratic views on the state); second, that the rectification of these opportunist views, and the recognition of Soviet power and its superiority to bourgeois parliamentary democracy proceeded most rapidly and extensively among those trends in the socialist parties of Europe and America that were most Marxist.
The struggle that Bolshevism waged against "Left" deviations within its own Party assumed particularly large proportions on two occasions: in 1908, on the question of whether or not to participate in a most reactionary "parliament" and in the legal workers’ societies, which were being restricted by most reactionary laws; and again in 1918 (the Treaty of Brest-Litovsk ), on the question of whether one "compromise" or another was permissible.
In 1908 the "Left" Bolsheviks were expelled from our Party for stubbornly refusing to understand the necessity of participating in a most reactionary "parliament".  The "Lefts"—among whom there were many splendid revolutionaries who subsequently were (and still are) commendable members of the Communist Party—based themselves particularly on the successful experience of the 1905 boycott. When, in August 1905, the tsar proclaimed the convocation of a consultative "parliament",  the Bolsheviks called for its boycott, in the teeth of all the opposition parties and the Mensheviks, and the "parliament" was in fact swept away by the revolution of October 1905.  The boycott proved correct at the time, not because nonparticipation in reactionary parliaments is correct in general, but because we accurately appraised the objective situation, which was leading to the rapid development of the mass strikes first into a political strike, then into a revolutionary strike, and finally into an uprising. Moreover, the struggle centred at that time on the question of whether the convocation of the first representative assembly should be left to the tsar, or an attempt should be made to wrest its convocation from the old regime. When there was not, and could not be, any certainty that the objective situation was of a similar kind, and when there was no certainty of a similar trend and the same rate of development, the boycott was no longer correct.
The Bolsheviks’ boycott of "parliament" in 1905 enriched the revolutionary proletariat with highly valuable political experience and showed that, when legal and illegal parliamentary and non-parliamentary forms of struggle are combined, it is sometimes useful and even essential to reject parliamentary forms. It would, however, be highly erroneous to apply this experience blindly, imitatively and uncritically to other conditions and other situations. The Bolsheviks, boycott of the Duma in 1906 was a mistake although a minor and easily remediable one. [*] The boycott of the Duma in 1907, 1908 and subsequent years was a most serious error and difficult to remedy, because, on the one hand, a very rapid rise of the revolutionary tide and its conversion into an uprising was not to be expected, and, on the other hand, the entire historical situation attendant upon the renovation of the bourgeois monarchy called for legal and illegal activities being combined. Today, when we look back at this fully completed historical period, whose connection with subsequent periods has now become quite clear, it becomes most obvious that in 1908-14 the Bolsheviks could not have preserved (let alone strengthened and developed) the core of the revolutionary party of the proletariat, had they not upheld, in a most strenuous struggle, the viewpoint that it was obligatory to combine legal and illegal forms of struggle, and that it was obligatory to participate even in a most reactionary parliament and in a number of other institutions hemmed in by reactionary laws (sick benefit societies, etc.).
In 1918 things did not reach a split. At that time the "Left" Communists formed only a separate group or "faction" within our Party, and that not for long. In the same year, 1918, the most prominent representatives of "Left Communism", for example, Comrades Radek and Bukharin, openly acknowledged their error. It had seemed to them that the Treaty of Brest-Litovsk was a compromise with the imperialists, which was inexcusable on principle and harmful to the party of the revolutionary proletariat. It was indeed a compromise with the imperialists, but it was a compromise which, under the circumstances, had to be made.
Today, when I hear our tactics in signing the Brest-Litovsk Treaty being attacked by the Socialist-Revolutionaries, for instance, or when I hear Comrade Lansbury say, in a conversation with me, "Our British trade union leaders say that if it was permissible for the Bolsheviks to compromise, it is permissible for them to compromise too", I usually reply by first of all giving a simple and "popular" example:
Imagine that your car is held up by armed bandits. You hand them over your money, passport, revolver and car. In return you are rid of the pleasant company of the bandits. That is unquestionably a compromise. "Do ut des" (I "give" you money, fire-arms and a car "so that you give" me the opportunity to get away from you with a whole skin). It would, however, be difficult to find a sane man who would declare such a compromise to be "inadmissible on principle", or who would call the compromiser an accomplice of the bandits (even though the bandits might use the car and the firearms for further robberies). Our compromise with the bandits of German imperialism was just that kind of compromise.
But when, in 1914-18 and then in 1918-20, the Mensheviks and Socialist-Revolutionaries in Russia, the Scheidemannites (and to a large extent the Kautskyites) in Germany, Otto Bauer and Friedrich Adler (to say nothing of the Renners and Co.) in Austria, the Renaudels and Longuets and Co. in France, the Fabians, the Independents and the Labourites in Britain entered into compromises with the bandits of their own bourgeoisie, and sometimes of the "Allied" bourgeoisie, and against the revolutionary proletariat of their own countries, all these gentlemen were actually acting as accomplices in banditry.
The conclusion is clear: to reject compromises "on principle", to reject the permissibility of compromises in general, no matter of what kind, is childishness, which it is difficult even to consider seriously. A political leader who desires to be useful to the revolutionary proletariat must be able to distinguish concrete cases of compromises that are inexcusable and are an expression of opportunism and treachery; he must direct all the force of criticism, the full intensity of merciless exposure and relentless war, against these concrete compromises, and not allow the past masters of "practical" socialism and the parliamentary Jesuits to dodge and wriggle out of responsibility by means of disquisitions on "compromises in general". It is in this way that the "leaders,, of the British trade unions, as well as of the Fabian society and the "Independent" Labour Party, dodge responsibility for the treachery they have perpetrated’ for having made a compromise that is really tantamount to the worst kind of opportunism, treachery and betrayal.
There are different kinds of compromises. One must be able to analyse the situation and the concrete conditions of each compromise, or of each variety of compromise. One must learn to distinguish between a man who has given up his money and fire-arms to bandits so as to lessen the evil they can do and to facilitate their capture and execution, and a man who gives his money and fire-arms to bandits so as to share in the loot. In politics this is by no means always as elementary as it is in this childishly simple example. However, anyone who is out to think up for the workers some kind of recipe that will provide them with cut-and-dried solutions for all contingencies, or promises that the policy of the revolutionary proletariat will never come up against difficult or complex situations, is simply a charlatan.
To leave no room for misinterpretation, I shall attempt to outline, if only very briefly, several fundamental rules for the analysis of concrete compromises.
The party which entered into a compromise with the German imperialists by signing the Treaty of Brest-Litovsk had been evolving its internationalism in practice ever since the end of 1914. It was not afraid to call for the defeat of the tsarist monarchy and to condemn "defence of country" in a war between two imperialist robbers. The parliamentary representatives of this party preferred exile in Siberia to taking a road leading to ministerial portfolios in a bourgeois government. The revolution that overthrew tsarism and established a democratic republic put this party to a new and tremendous test—it did not enter into any agreements with its "own" imperialists, but prepared and brought about their overthrow. When it had assumed political power, this party did not leave a vestige of either landed or capitalist ownership. After making public and repudiating the imperialists’ secret treaties, this party proposed peace to all nations, and yielded to the violence of the Brest-Litovsk robbers only after the Anglo-French imperialists had torpedoed the conclusion of a peace, and after the Bolsheviks had done everything humanly possible to hasten the revolution in Germany and other countries. The absolute correctness of this compromise, entered into by such a party in such a situation, is becoming ever clearer and more obvious with every day.
The Mensheviks and the Socialist-Revolutionaries in Russia (like all the leaders of the Second International throughout the world, in 1914-20) began with treachery—by directly or indirectly justifying "defence of country", i.e., the defence of their own predatory bourgeoisie. They continued their treachery by entering into a coalition with the bourgeoisie of their own country, and fighting, together with their own bourgeoisie, against the revolutionary proletariat of their own country. Their bloc, first with Kerensky and the Cadets, and then with Kolchak and Denikin in Russia—like the bloc of their confreres abroad with the bourgeoisie of their respective countries—was in fact desertion to the side of the bourgeoisie, against the proletariat. From beginning to end, their compromise with the bandits of imperialism meant their becoming accomplices in imperialist banditry.
 Lenin is referring probably to his article "What Should Not Be Copied from the Gennan Labour Movement", published in the Bolshevik magazine Prosveshcheniye in April 1914 (see present edition, Vol. 20, pp. 254-58). Here Lenin exposed the treacherous behaviour of Karl Legien, the German Social-Democrat who in 1912, in addressing the Congress of the U.S.A., praised U.S. official circles and bourgeois parties.
 Spartacists—members of the Spartacus League founded in January 1916, during the First World War, under the leadership of Karl Liebknecht, Rosa Luxemburg, Franz Mehring and Clara Zetkin. The Spartacists conducted revolutionary anti-war propaganda among the masses, and exposed the expansionist policy of German imperialism and the treachery of the Social-Democratic leaders. However, the Spartacists—the German Left wing—did not get rid of their semi-Menshevik errors on the most important questions of theory and tactics. A criticism of the German Left-wing’s mistakes is given in Lenin’s works "On Junius’s Pamphlet" (see present edition, Vol. 22, pp. 297-305), "A Caricature of Marxism and Imperialist Economism" (see Vol. 23, pp. 28-76) and elsewhere.
In April 1917, the Spartacists joined the Centrist Independent Social-Democratic Party of Germany, preserving their organisational independence. After the November 1918 revolution in Germany, the Spartacists broke away from the "Independents", and in December of the same year founded the Communist Party of Germany.
 The reference is to Frederick Engels’s letter to August Bebel, written on March 18-28, 1875.
 The Treaty of Brest Litovsk was signed between Soviet Russia and the powers of the Quadruple Alliance (Germany, Austria-Hungary, Bulgaria and Turkey) on March 3, 1918, at Brest Litovsk and ratified on March 15 by the Fourth (Extraordinary) All-Russia Congress of Soviets. The peace terms were very harsh for Soviet Russia. According to the treaty, Poland, almost all the Baltic states, and part of Byelorussia were placed under the control of Germany and Austria-Hungary. The Ukraine was separated from Soviet Russia, becoming a state dependent on Germany. Turkey gained control of the cities of Kars, Batum and Ardagan. In August 1918, Germany imposed on Soviet Russia a supplementary treaty and a financial agreement containing new and exorbitant demands.
The treaty prevented further needless loss of life, and gave the R.S.F.S.R. the ability to shift it’s attention to urgent domestic matters. The signing of the Treaty of Brest-Litovsk promoted the struggle for peace among the broad masses of all the warring nations, and denounced the war as a struggle between imperialist powers. On November 13, 1918, following the November revolution in Germany--the overthrow of the monarchist regime—the All-Russia Central Executive Committee annulled the predatory Treaty of Brest-Litovsk.
 The reference is to the otzovists [the term otzovist derives from the Russian verb "otozvat" meaning "to recall".—Ed.] and ultimatumists, the struggle against whom developed in 1908, and in 1909 resulted in the expulsion of A. Bogdanov, the otzovist leader, from the Bolshevik Party. Behind a screen of revolutionary phrases, the otzovists demanded the recall of the Social-Democrat deputies from the Third Duma and the cessation of activities in legal organisations such as the trade unions, the co-operatives, etc. Ultimatumism was a variety of otzovism. The ultimatumists did not realise the necessity of conducting persistent day-by-day work with the Social-Democrat deputies, so as to make them consistent revolutionary parliamentarians. They proposed that an ultimatum should be presented to the Social-Democratic group in the Duma, demanding their absolute subordination to decisions of the Party’s Central Committee; should the deputies fail to comply, they were to be recalled from the Duma. A conference of the enlarged editorial board of the Bolshevik paper Proletary, held in June 1909, pointed out in its decision that "Bolshevism, as a definite trend in the R.S.D.L.P., had nothing in common either with otzovism or with ultimatumism". The conference urged the Bolsheviks "to wage a most resolute struggle against these deviations from the path of revolutionary Marxism" (KPSS v rezolutsiyakh i resheniyakh syezdov, konferentsii i plenumov TsK [The C.P.S.U. in the Resolutions and Decisions of Its Congresses, Conferences and Plenums of the Central Committee], Part I, 1954, p. 221).
 On August 6 (19), 1905, the tsar’s manifesto was made public, proclaiming the law on the setting up of the Duma and the election procedures. This body was known as the Bulygin Duma, after A.G. Bulygin, the Minister of the Interior, whom the tsar entrusted with drawing up the Duma draft. According to the latter, the Duma had no legislative functions, but could merely discuss certain questions as a consultative body under the tsar. The Bolsheviks called upon the workers and peasants to actively boycott the Bulygin Duma, and concentrate all agitation on the slogans of an armed uprising, a revolutionary army, and a provisional revolutionary government. The boycott campaign against the Bulygin Duma was used by the Bolsheviks to mobilise all the revolutionary forces, organise mass political strikes, and prepare for an armed uprising. Elections to the Bulygin Duma were not held and the government was unable to convene it. The Duma was swept away by the mounting tide of the revolution and the all-Russia October political strike of 1905.
 Lenin is referring to the all-Russia October political strike of 1905 during the first Russian revolution. This strike, which involved over two million people, was conducted under the slogan of the overthrow of the tsarist autocracy, an active boycott of the Bulygin Duma, the summoning of a Constituent Assembly and the establishment of a democratic republic. The all-Russia political strike showed the strength of the working-class movement, fostered the development of the revolutionary struggle in the countryside, the army and the navy. The October strike led the proletariat to the December armed uprising. Concerning the October strike, see the article by V. I. Lenin ’The All-Russia Political Strike".
[*] What applies to individuals also applies—with necessary modifications—to politics and parties. It is not he who makes no mistakes that is intelligent. There are no such men, nor can there be. It is he whose errors are not very grave and who is able to rectify them easily and quickly that is intelligent.
