Trial of the 149 (Estonian: 149 protsess) is the name given to the legal proceedings against 149 communists in Estonia that lasted from 10 to 27 November 1924. Many defendants were accused of high treason. One of them – Jaan Tomp – was sentenced to death and 39 other people to forced labour for life. The trial of the 149 was one of the largest trials in the pre-war Republic of Estonia.
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" (Tööliste kelder) 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 (Töörahva Ühine Väerind). 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.
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.
