Stalin travelled to the Fifth RSDLP Congress, held in London in May–June 1907, via St Petersburg, Stockholm, and Copenhagen. While in Denmark, he made a detour to Berlin for a secret meeting with Lenin to discuss the robberies. Stalin arrived in England and Harwich and took the train to London. There, he rented a room in Stepney, part of the city's East End that housed a substantial Jewish émigré community from the Russian Empire. The congress took place at a church in Islington. He remained in London for about three weeks, helping to nurse Tskhahaya after the latter fell ill. He returned to Tiflis via Paris.
