This series contains the records of John Diefenbaker’s personal and political activities before his election to Parliament in May 1940, excluding his legal papers (MG 01/I Legal Series) and his family correspondence (MG 01/V Legal Series). There is material about his education at the University of Saskatchewan and his military career during the First World War. There is a large section on the Saskatchewan provincial Conservative Party which he led from 1936 to 1939. This series also contains transcripts of the Bryant Commission Inquiry into jails and provincial police for which Diefenbaker served as legal counsel. Diefenbaker received many requests for assistance from members of the general public which provide information about the wide range of political, social and financial problems Saskatchewan experienced in the 1920s and 1930s.
