During 1926–1948 the Chairman of the Collegium was Vasiliy Ulrikh.[2]
The role of the Military Collegium drastically changed after June 1934, when it was assigned the duty to consider cases that fell under Article 58, counter-revolutionary activity.
During the Great Purge of 1937–1938 the Military Collegium tried relatively prominent figures, usually based on the lists approved personally by Joseph Stalin,[3] the majority of Article 58 cases having been processed extrajudicially by NKVD troikas. In particular, the Military Collegium conducted the major Soviet show trials.[4]
