These files date from 1915 to 1921. The material contains reports and memos, newspaper extracts, photos, reports on the movements and activities of Lenin and his associates, and Secret Intelligence Service (SIS) documents.

Bolsheviki Party MI5 Files
In addition to the 457 pages above are 134 pages of MI5 Files covering the Bolsheviki Party. This collection of papers dating from July 1917 to August 1918, covers Soviet political parties, particularly the Bolsheviki, including comments on Lenin, Trotsky and others. A highlight from the material is a document listing the 51 most important things to know about the Bolshevikis including anti-Semitic remarks about Jewish control of the party.
