This article analyses the distinctive characteristics of how the League of Nations sought to publicly legitimise itself from 1919 to 1939. Discussing the work of the Information Section of the League Secretariat, it traces the organisational development of this section throughout the interwar years and argues that a preference of ‘collaboration’ through liaison with influential members of the public in the League's member states permeated this section's work, and that this strategy was, in the eyes of League officials, necessitated by the tight political constraints the Secretariat was subjected to rather than the result of an inherent ‘elitism’ of the officials.
