I'm pretty sure that not many people know that all of the founding fathers of the USSR were in London together in 1907. Stalin, Lenin, Trotsky, Gorky, Litvinov, Alexandra Kollontai & Rosa Luxemburg visited Hackney for the 5th Congress of the Russian Social Democrat Workers' Party, held at the Brotherhood Church, a Fabian socialist institute, which once stood on Southgate Road, London N1. It was Stalin's only time in London and he never spoke about it in later life.

The Russian Social-Democratic Labour Party, or RSDLP (Russian Росси́йская Социа́л-Демократи́ческая Рабо́чая Па́ртия = РСДРП), also known as the Russian Social-Democratic Workers' Party and the Russian Social-Democratic Party, was a revolutionary socialist Russian political party formed in 1898 in Minsk to unite the various revolutionary organizations into one party. The RSDLP later split into Bolshevik and Menshevik factions, with the Bolsheviks eventually becoming the Communist Party of the Soviet Union. The Mezhraiontsy were also formed from this party.
