He is the author, co-author, and co-editor of thirty books and collections, and the author or co-author of hundreds of articles or chapters in peer-reviewed journals, university presses, encyclopedia articles, and other forms of publication, including op-eds. His three-volume study, A Treatise on Northern Ireland, published by Oxford University Press, was positively reviewed in the Dublin Review of Books, the Irish News, and the Irish Times, and in April 2020 it received the James S. Donnelly Sr. best book prize in History and Social Science of the American Conference on Irish Studies, and paperback copies were published the same year. In 2021 he was one of the co-authors of the Final Report of the Working Group on Unification Referendums on the Island of Ireland (The Constitution Unit, UCL). He held a Fulbright Fellowship at the National University of Ireland-Galway, in 2021-22 writing a book, Making Sense of a United Ireland, which was published by Penguin in Dublin on September 1 2022. It received the Brian Farrell best book prize of the Political Studies Association of Ireland in 2023.
Professor O’Leary is the inaugural winner of the Juan Linz prize of the International Political Science Association for contributions to the study of multinational societies, federalism and power-sharing, and in 2016 he was elected an honorary member of the Royal Irish Academy, principally because of his contributions to the field of power-sharing. In addition to his scholarly work, O’Leary has been a political and constitutional advisor to the United Nations, the European Union, the Kurdistan Regional Government of Iraq, the Governments of the UK and Ireland, and to the British Labour Party (before and during the Irish peace process).
O’Leary was born in Cork, Ireland, but his early childhood was mostly spent in Nigeria. Between the ages 8 and 18 he grew up in Northern Ireland and the Sudan. He attended St MacNissi’s College, Garron Tower, Northern Ireland, 1969-76, as his high school. He received the Irish Times/Trinity College Dublin all-Ireland best individual speaker prize in school debating in 1975, and the Joint Association of Classical Teachers prize for first place in Advanced level Ancient History in 1976. He won an open scholarship to Keble College Oxford University in 1977, where he was tutored by Larry Siedentop, the scholar of Tocqueville and the European Union, and by the economist Paul Collier. O’Leary graduated with a first class degree in PPE (Philosophy, Politics and Economics). He wrote his PhD thesis at the London School of Economics & Political Science. Supervised by the late Professor T.J. Nossiter, it was examined by Professors Ernest Gellner and Nicos Mouzelis. It won the Robert McKenzie Memorial Prize for the best PhD at LSE presented in 1988, and was published as The Asiatic Mode of Production: Oriental Despotism, Historical Materialism and Indian History, with a Foreword by the late Ernest Gellner. In 2001 this book was elected one of 202 central works of sociology in the 20th century in the digest Schlüsselwerke der Soziologie, eds. S. Papcke & G.W. Oesterdiekhoff (eds.) (Berlin: Westdesutscher Verlag, 2001, pp. 372-4).
Between 1983 and 2002, O’Leary was on the faculty of the London School of Economics & Political Science, where he was successively Lecturer, Senior Lecturer, Reader, and Professor of Political Science; the first elected head of the LSE Government Department (1998-2001); and an elected Academic Governor (2000-1). He has been a visiting professor of political science at Uppsala University, the University of Western Ontario, Canada, and at Queen's University Belfast, and a Moore fellow at the National University of Ireland-Galway, and subsequently a Fulbright fellow at the University of Galway. He has been nominated by the Government of Ireland to be a member of the Governing Authority of University College Cork (2023-27).
Brendan O’Leary was a political advisor to the British Labour Shadow Cabinet on Northern Ireland between 1987-8 and 1996-7, advising the late Kevin McNamara and the late Marjorie (“Mo”) Mowlam, shadow Secretaries of State for Northern Ireland. He also advised Irish, British, and American ministers and officials, and the Irish-American Morrison delegation (particularly the late Chuck Feeney) during the Northern Ireland peace process. He appeared as an expert witness before the US Congress, and was a guest at the White House in 1994, 1995 and 1998. His work with John McGarry on police reform was singled out in the press for influencing the independent commission on police reform which reported in 1999 (the Patten Commission).
O’Leary has since been a constitutional advisor for the European Union and the United Nations in the promotion of the confederal and federal re-building of Somalia, and for the United Kingdom’s Department of International Development in consultancies on power-sharing in coalition governments in Kwa-Zulu Natal, South Africa, and in Nepal.
For the United Nations O’Leary was among the principal consultants to its 2004 United Nations Human Development Report on Culture and Liberty, co-edited by Amartya Sen. In 2009-2010 he was seconded to the UN as the Senior Advisor on Power-Sharing in the Standby Team of the Mediation Support Unit of the Department of Political Affairs. In that capacity he had field experience in numerous conflict-sites, including in Sudan, South Sudan, Nepal and Kyrgyzstan, and chaired a seminar of the United Nations General Assembly on mediation.
Since 2003 O’Leary has regularly been an international constitutional advisor to the Kurdistan Regional Government in Iraq, assisting in the negotiation of the Transitional Administrative Law (2004); electoral systems design (2004-5); the Constitution of Iraq (2005); the draft Constitution of the Kurdistan Region (2005-); and in monitoring violations of the Constitution of Iraq by its federal government. He has been an expert witness on Iraq and Kurdistan to branches of the US Government, and to the United Kingdom's Iraq Commission, and an expert witness in court cases related to Iraq's Constitution.
