What happened
Lenin had spent the war years in exile in Switzerland. On 9 April 1917, he and 31 other exiles, negotiated through the Swiss socialist Fritz Platten, boarded a train in Zurich that the German government allowed to cross its territory sealed, so no one could get on or off, in the hope that Lenin's return would destabilize Russia's war effort. Lenin arrived at Petrograd's Finland Station on 16 April 1917 to a large crowd. The next day he read out what became known as the April Theses, ten points rejecting any cooperation with the Provisional Government, demanding "all power to the soviets," calling for Russia's immediate exit from the war, and calling for the nationalization of land and banks.
Why it matters
The April Theses broke sharply with other socialists who wanted to support the Provisional Government, and it gave the Bolsheviks a clear, radical program while their rivals hedged. Germany's gamble on Lenin paid off for Berlin in the short term: Russia's war effort collapsed within the year, and Lenin's party rode the theses' demands, peace, land, and soviet power, straight to the events of October.
How we know
The train's departure from Zurich, Fritz Platten's negotiation with Germany, and Lenin's arrival date at Finland Station are documented across multiple contemporary and historical accounts of April 1917.
