The February Revolution had resulted in the abdication of Tsar Nicholas II, the collapse of Imperial Russia, and the establishment of the liberal Provisional Government under Georgy Lvov and later Alexander Kerensky.
The Swiss communist Fritz Platten managed to negotiate with the German government for the safe passage of Lenin and his company through Germany by rail on the so-called "sealed train".
Once through Germany, Lenin continued by ferry to Sweden, and the remainder of the journey through Scandinavia was subsequently arranged by Swedish communists Otto Grimlund and Ture Nerman.
In the Theses, Lenin[3] After the February Revolution, Bolshevik leaders returning from exile (such as Lev Kamenev) were arguing a much more moderate line, that Russian involvement in the war could be justified and that there should be cooperation with the liberals in the Provisional Government.
Joseph Stalin who had initially supported co operation with the Provisional Government changed his position upon reading the April Theses and spoke in favour of the programme at the Bolshevik city meeting in Petrograd.
