During the 1920s, Estonia was a politically stable country with a mainly agrarian economy, the industrial base was relatively small and the peasantry were largely satisfied with the government's land redistribution policies of 1919–1920, thus there was little sympathy for the communists. Following the failed Hamburg Uprising and Bulgarian September Uprising, the Estonian authorities decided to crack down on the small but very militant Estonian Communist Party. On 21 January 1924, the security police raided a club called "The Workers' Cellar" where 185 representatives of workers' organisations had gathered for a meeting. The names of people present were recorded and the chairmen of the meeting – Hendrik Allik, Paul Keerdo and Jaan Tomp – were arrested. That same day, Vladimir Kangur was arrested in Narva. They all were accused of being the founders of the Workers' United Front. Several members of the Riigikogu also belonged to this organisation. This raid was the first in a series of operations that led to the arrest of 200 people. Communist newspapers and organisations were shut down. 229 workers' societies were dissolved as they were accused of unconstitutional activities. Some of the arrested communists managed to escape and they could not be tried. In the end 149 people were prosecuted.
Trial
Most of the accused did not admit guilt. Some of those who did came up with the excuse that they needed the money provided by Soviet communists to improve their life. Of 149 defendants, 88 declined a lawyer. Not all defendants were present in the courtroom, and some had to be removed as they started to protest. One of the removed persons was Vladimir Kangur, a member of Riigikogu. Some people could not be arrested and tried because of their status as members of parliament. Some of these included Eliise Priks, Eduard Luts and Aleksander Rimmel. The defendants faced different charges. The whole bill of indictment was 150 pages long. The most general and common charge was "participation in a pan-Estonian secret communist organisation".

The verdict was read on 27 November 1924.
