This series contains correspondence, notes, articles, pamphlets, reports and source files related to the beginning of the organization and the specific needs and conditions of Armenia and Syria. The correspondence documents the experiences of those in war-torn areas and the need for aid. The bulk of William Walker Rockwell's extensive correspondence is from 1911-1917. The letters go into detail regarding conditions in Armenia, such as deportations and poor treatment of individuals. Correspondence is from individuals and locations throughout the world, such as Germany and Switzerland. Rockwell also wrote to Ambassadors Henry Morgenthau and Abram I. Elkus, US Ambassadors to Turkey. Many of the documents contain copies of other material not directly related to the ACASR, such as other committees with related goals. Rockwell's materials also include his own writings, such as for the pamphlet, The Pitiful Plight of the Assyrian Christians, 1916. The remainder of the series offers source files, also collected by Rockwell, on ACASR work and what other organizations, such as the Federal Council of Churches and the American Board of Commissioners for Foreign Missions, were doing to help.
