International Treaties

World Treaty Index
An electronic treaty database. The World Treaty Index was first published by ABC-Clio in 1974, ten years after its founder, Dr. Peter Rohn, envisioned a comprehensive resource for treaty research. From 1999-2009, the World Treaty Index was administered under the auspices of the Human Rights Education and Research Network by Glenda Pearson of the University of Washington Libraries. Once fully complete, the World Treaty Index will feature every known international agreement in the 20th Century. This includes tens of thousands agreements entered into by hundreds of countries and international organizations. Currently, this website only contains treaties signed between 1945 and 1999. Remaining treaties are being added through 2010 and early 2011.
