Visualizing the League of Nations Secretariat – a Digital Research Tool

This project created an interactive digital research tool for the League of Nations Secretariat (1919-1946) using prosopographical data.

League of Nations Secretariat

Visualizing the League of Nations Secretariat (VisuaLeague) is a research tool where users can (1) select, combine and search on nationality, gender, institutional entity, division and position within any given time span of the League Secretariat’s existence freely, (2) visualize statistical representations of your choices and (3) browse and download prosopographical data curated by you.

VisuaLeague is created by using the individual personnel files of the League of Nations Secretariat, and the prosopographical work of the LONTAD and LONSEA projects.
