The Institute of Pacific Relations (IPR) was an international NGO established in 1925 to provide a forum for discussion of problems and relations between nations of the Pacific Rim. The International Secretariat, the center of most IPR activity over the years, consisted of professional staff members who recommended policy to the Pacific Council and administered the international program. The various national councils were responsible for national, regional and local programming. Most participants were elite members of the business and academic communities in their respective countries. Funding came largely from businesses and philanthropies, especially the Rockefeller Foundation. IPR international headquarters were in Honolulu until the early 1930s when they were moved to New York and the American Council emerged as the dominant national council.
IPR was founded in the spirit of Wilsonianism, an awareness of the United States' new role as a world power after World War I, and a belief that liberal democracy should be promoted throughout the world. To promote greater knowledge of issues, the IPR supported conferences, research projects and publications, and after 1932 published a quarterly journal Pacific Affairs. After World War II, Cold War charges that the IPR was infiltrated with Communists led to Congressional hearings and loss of tax exempt status. Many IPR members had liberal left orientations typical of internationalists of the 1930s, some ten IPR associates were shown to have been Communists, others were sympathetic to the Soviet Union, and the anti-imperialist tone of the leadership aroused resentment from some of the colonial powers, but the more dramatic charges, such as that the IPR was responsible for the fall of China, have not been generally accepted.
The IPR was the result of two sets of organizers, one in New York, another in Hawai'i. The New York-based effort was organized by Edward C. Carter, Carter, after graduating from Harvard in 1906, joined the Student Volunteer Movement with the YMCA in India, then worked with the Y in France during World War I. After the war he joined The Inquiry, a liberal Protestant commission with a flavor both genteel and militant which organized conferences and publications on labor, race relations, business ethics, and international peace. Among Carter's constituents were John D. Rockefeller, III, Abby Aldrich Rockefeller, daughter of the Rhode Island U.S. Senator, and Dr. Ray Lyman Wilbur, President of Stanford University. Wilbur argued that a new organization devoted to Pacific affairs would fill a gap not addressed by East Coast foreign policy groups. Meanwhile, in Hawai'i, another group was organizing under the leadership of local business interests.
