 But in 1910, exasperated by Jogiches's refusal to allow discussion within the SDKPiL over issues such as whether to participate in the recently legalised trade unions (which Jogiches opposed), Hanecki toured Germany and Austria, organising what became known as the "Roslamowcy" (Rozlamovists - 'Splitters').This group held its own conference in Warsaw in December, and subsequently created a separate organisation, of which Hanecki was the undisputed leader.Other members included Karl Radek, Josef Unshlicht, Yakov Dolecki - all later high ranking officials in the Soviet Union - and two future leaders of the Polish Communist Party, Henryk Domski and Julian Lenski.
