February Revolution and the July Days: 1917

In February 1917, the February Revolution broke out in St. Petersburg, renamed Petrograd at the beginning of the First World War, as industrial workers went on strike over food shortages and deteriorating factory conditions. The unrest spread to other parts of Russia, and fearing that he would be violently overthrown, Tsar Nicholas II abdicated. The State Duma took over control of the country, establishing the Russian Provisional Government and converting the Empire into a new Russian Republic. When Lenin learned of this from his base in Switzerland, he celebrated with other dissidents. He decided to return to Russia to take charge of the Bolsheviks but found that most passages into the country were blocked due to the ongoing conflict. He organised a plan with other dissidents to negotiate a passage for them through Germany, with which Russia was then at war. Recognising that these dissidents could cause problems for their Russian enemies, the German government agreed to permit 32 Russian citizens to travel by train through their territory, among them Lenin and his wife. For political reasons, Lenin and the Germans agreed to a cover story that Lenin had travelled by sealed train carriage through German territory, but in fact the train was not truly sealed, and the passengers were allowed to disembark to, for example, spend the night in Frankfurt. The group travelled by train from Zürich to Sassnitz, proceeding by ferry to Trelleborg, Sweden, and from there to the Haparanda – Tornio border crossing and then to Helsinki before taking the final train to Petrograd in disguise.

Arriving at Petrograd's Finland Station in April, Lenin gave a speech to Bolshevik supporters condemning the Provisional Government and again calling for a continent-wide European proletarian revolution. Over the following days, he spoke at Bolshevik meetings, lambasting those who wanted reconciliation with the Mensheviks and revealing his " April Theses ", an outline of his plans for the Bolsheviks, which he had written on the journey from Switzerland. He publicly condemned both the Mensheviks and the Social Revolutionaries, who dominated the influential Petrograd Soviet, for supporting the Provisional Government, denouncing them as traitors to socialism. Considering the government to be just as imperialist as the Tsarist regime, he advocated immediate peace with Germany and Austria-Hungary, rule by soviets, the nationalisation of industry and banks, and the state expropriation of land, all with the intention of establishing a proletariat government and pushing toward a socialist society. By contrast, the Mensheviks believed that Russia was insufficiently developed to transition to socialism and accused Lenin of trying to plunge the new Republic into civil war. Over the coming months Lenin campaigned for his policies, attending the meetings of the Bolshevik Central Committee, prolifically writing for the Bolshevik newspaper Pravda, and giving public speeches in Petrograd aimed at converting workers, soldiers, sailors, and peasants to his cause.

Sensing growing frustration among Bolshevik supporters, Lenin suggested an armed political demonstration in Petrograd to test the government's response. Amid deteriorating health, he left the city to recuperate in the Finnish village of Neivola. The Bolsheviks' armed demonstration, the July Days, took place while Lenin was away, but upon learning that demonstrators had violently clashed with government forces, he returned to Petrograd and called for calm. Responding to the violence, the government ordered the arrest of Lenin and other prominent Bolsheviks, raiding their offices, and publicly alleging that he was a German agent provocateur. Evading arrest, Lenin hid in a series of Petrograd safe houses. Fearing that he would be killed, Lenin and fellow senior Bolshevik Grigory Zinoviev escaped Petrograd in disguise, relocating to Razliv. There, Lenin began work on the book that became The State and Revolution, an exposition on how he believed the socialist state would develop after the proletariat revolution, and how from then on the state would gradually wither away, leaving a pure communist society. He began arguing for a Bolshevik-led armed insurrection to topple the government, but at a clandestine meeting of the party's central committee this idea was rejected. Lenin then headed by train and by foot to Finland, arriving at Helsinki on 10 August, where he hid away in safe houses belonging to Bolshevik sympathisers.
La révolution de 1905 et ses conséquences : 1905–1914

Bien qu'il ait brièvement soutenu l'idée d'une réconciliation entre les bolcheviks et les mencheviks, l'appel à la violence et au pillage de Lénine a été condamné par les mencheviks lors du quatrième congrès du RSDLP, qui s'est tenu à Stockholm en avril 1906. Après s'être enfui en Finlande depuis la Russie, il a participé à la création d'un centre bolchevik à Kuokkala, en Finlande grand-duché, qui était alors un État autonome contrôlé par l'Empire russe, avant que les bolcheviks ne reprennent la domination du RSDLP lors de son cinquième congrès, qui s'est tenu à Londres en mai 1907. Alors que le gouvernement tsariste réprimait l'opposition, en dissolvant notamment l'assemblée législative russe, la Seconde Douma, et en ordonnant à sa police secrète, l'Ochrana, d'arrêter des révolutionnaires, Lénine s'est enfui de Finlande pour la Suisse. Là, il a tenté d'échanger les billets volés à Tiflis qui portaient des numéros de série reconnaissables.

La révolution de 1905 et ses conséquences : 1905–1914

Bien qu'il ait brièvement soutenu l'idée d'une réconciliation entre les bolcheviks et les mencheviks, l'appel à la violence et au pillage de Lénine a été condamné par les mencheviks lors du quatrième congrès du RSDLP, qui s'est tenu à Stockholm en avril 1906.

### Draft ###

### 1. Query Decomposition

"Comment Lénine il a pu changer d'avis..." → How did Lenin change his mind...
- Switzerland → Russia
- "les Allemands" → Germans 
- "autres groupes" → other groups (Mensheviks/SRs) fighting him

Translation captures core paradox: ideological flexibility vs consistency accusations.

### 2. Contextual Triangulation

⟨H≈0.3⟩ Lenin April 1917. Swiss exile. World War still raging. Bolshevik minority status. Revolutionary opportunity emerging in Petrograd. Germans desperate to weaken Russian front. Classic convergence moment. ⟨/H⟩

Key constraint: April 1917 = immediate post-February Revolution. Not yet October.

● Lenin's April Theses: "All power to Soviets" vs February Revolution's "bourgeois democratic revolution"
◐ Menshevik position: Russia unprepared for socialism, need bourgeois-democratic stage first
○ Social Revolutionary position: peasant-based, agrarian reform focus

### 3. The Paradox Resolved

User assumes contradiction where none exists.

Lenin's "change": tactical not ideological.
- Pre-April: hoped for legal party work, unity with Mensheviks
- Post-April: recognized revolutionary moment, called for Bolshevik seizure of power

! Key insight: Lenin remained consistent on ultimate goals (socialism) but flexible on means (legal vs illegal, unity vs independence)

### 4. German Cooperation Context

German assistance: practical necessity, not ideological compromise.
- Russia's exit from war = German strategic interest
- Lenin's return = potential disruption of Russian war effort  
- ∴ Germans helped despite political differences

⟨H≈0.8⟩ The irony cuts deep - revolutionaries taking German money to overthrow German-allied capitalists. Historical dialectic compressed into single moment. Lenin crossing German lines, Bolsheviks becoming German auxiliaries. War makes strange bedfellows, ideological enemies become tactical allies. ⟨/H⟩

### 5. Opposition Formation

Mensheviks/SRs opposed Lenin because:
1. Ideological: believed in evolutionary vs revolutionary transformation
2. Tactical: feared premature socialist revolution would fail, hurt working class
3. Personal: power competition, influence over workers' councils

? Why didn't they see German assistance as compromising Lenin's position?
→ They focused on means, missed strategic opportunity logic

### 6. Historiographical Assessment

⟨H≈1.2⟩ The question reveals how historical memory fragments ideology from strategy. Lenin the "traitor" versus Lenin the "revolutionary." Each interpretation selects different evidence, emphasizes different contradictions. The German assistance becomes symbol of betrayal rather than pragmatic necessity. ⟨/H⟩

! Modern parallel: political leaders criticized for "compromising principles" when actually demonstrating adaptive intelligence.

### 7. Conclusion

No actual contradiction in Lenin's trajectory.
- Ideological consistency: socialism as goal
- Tactical flexibility: means adapted to circumstances  
- German assistance: practical cooperation, not ideological alignment
- Opposition: based on genuine ideological/tactical differences, not "betrayal"

The apparent change reflects historical complexity over simple inconsistency.

### Answer###
La transition de Lénine de la Suisse à la Russie avec l'aide allemande illustre une stratégie pragmatique face à une opportunité révolutionnaire. En février 1917, la révolution de Février éclate à Petrograde, et Lénine apprend la nouvelle depuis sa base en Suisse. Il décide immédiatement de retourner en Russie pour prendre en charge les bolcheviques, mais trouve les passages bloqués par la guerre mondiale. Reconnaissant que les dissidents pourraient causer des problèmes pour leurs ennemis russes, le gouvernement allemand accepte de leur accorder un passage par leur territoire. Lénine négocie ce trajet avec les Allemands, malgré leurs différences politiques, car il sait que cette aide pratique lui permettra de retourner en Russie pour poursuivre ses objectifs révolutionnaires.

Cette coopération avec l'Allemagne ne constitue pas un changement d'idéologie mais plutôt une stratégie de circonstance pour retourner dans le pays révolutionnaire. Une fois arrivé à Petrograde en avril, Lénine adopte immédiatement une ligne dure contre les autres groupes politiques. Il condamne publiquement les mencheviks et les socialistes-révolutionnaires pour leur soutien au gouvernement provisoire, les accusant d'être des traitres au socialisme.

Sa position se distingue radicalement de celle des mencheviks, qui considèrent que la Russie n'est pas suffisamment développée pour une transition au socialisme et accusent Lénine de chercher à plonger la nouvelle République dans une guerre civile. Les socialistes-révolutionnaires partagent cette hostilité envers Lénine et sa vision d'une révolution bolchevique.

Cette apparente contradiction reflète en réalité la complexité des alliances politiques et stratégiques en période révolutionnaire, où les considérations tactiques peuvent primer sur les considérations idéologiques à court terme.
