The ANU has one of the largest concentrations of expertise on international relations and diplomacy, strategic studies, and comparative politics in the world. In recognition of this expertise, the University, supported by the Federal Government's Department of Education, Science, and Training, has constructed a major new facility to house the Asia-Pacific College of Diplomacy, the Department of International Relations, the Strategic and Defence Studies Centre, and the Department of Political and Social Change. The building is named 'The Hedley Bull Centre', in honour of Australia's most celebrated international relations scholar. Professor Hedley Bull was joint Head of the Department of International Relations from 1966 to 1976, and it was during this period that he wrote his most famous work, The Anarchical Society.
