Hugo Urbahns

Hugo Urbahns was a German communist revolutionary and politician.
He was involved in the Communist Party of Germany in the 1920s. He was jailed for his role in the Hamburg Uprising of 1923, and spent time on hunger strike.
He was expelled from the KPD in the late 1920s, and became a leader of the Leninbund, a left split from the KPD.
For a time he had links with Leon Trotsky, but they drifted apart over a number of issues, including Urbahns' development of "third campist" positions that the Soviet Union was no longer a workers' state.
