Introduction
John Bew is a British historian, author, professor and foreign-policy specialist whose career has connected academic research with the practical world of government. He is Professor of History and Foreign Policy in the Department of War Studies at King’s College London, where his research covers history, politics, conflict, British foreign policy and national identity.
Bew has become particularly well known for studying how historical experience can help explain contemporary political and strategic decisions. His books on figures such as Clement Attlee and Castlereagh, together with his research on realpolitik, have established him as an influential historian of British statecraft.
His career later moved beyond academia. In 2019, he joined No. 10 Downing Street as Foreign Policy Adviser to the Prime Minister, eventually serving through four prime ministers and two general elections.
Who Is John Bew?
John Bew is primarily known as a historian and foreign-policy expert. His academic work examines the relationship between history and political decision-making, particularly in Britain and the wider international system.
At King’s College London, his research interests include terrorism and political violence, engagement with terrorist groups, national identity and civic culture in British and Irish history, British foreign policy and Britain’s role during the Napoleonic Wars.
This combination of historical research and contemporary policy analysis has become a defining feature of his career.
Early Academic Career
Bew developed his academic career through historical research before moving into senior positions at King’s College London. His early scholarship was strongly connected with British and Irish political history, including the history of Belfast and Unionism.
His research eventually expanded toward broader questions of diplomacy, statecraft and international relations. This helped establish the foundation for his later work on realpolitik and British foreign policy.
His academic interests have allowed him to approach modern political questions through historical examples rather than viewing contemporary events in isolation.
John Bew and His Books
John Bew has written five books, with several becoming important contributions to modern political and historical scholarship.
The Glory of Being Britons
One of Bew’s early books was The Glory of Being Britons: Civic Unionism in Nineteenth-Century Belfast. The work explored civic identity, Unionism and political culture in nineteenth-century Belfast.
The subject reflected Bew’s Northern Irish background while establishing his reputation as a serious historian of British and Irish political history.
Talking to Terrorists
Bew also co-authored Talking to Terrorists: Making Peace in Northern Ireland and the Basque Country. The book examined the challenges involved in dealing with political organizations connected with violence and explored lessons from peace processes.
The subject connects closely with his wider academic interest in terrorism, political violence and negotiations.
Castlereagh
Another major work is Castlereagh: A Life, which examines Robert Stewart, Viscount Castlereagh, a central British statesman and diplomat during the period surrounding the Napoleonic Wars.
Through Castlereagh, Bew explored diplomacy, war, political leadership and the difficult balance between national interests and international stability.
Realpolitik: A History
Realpolitik: A History became one of Bew’s most important works on foreign policy.
The book examines the historical development of realpolitik and considers how states balance ideals, interests, power and practical political judgment. The subject became especially relevant to discussions about Britain’s international role.
Bew researched the history of realpolitik during his time as Henry A. Kissinger Chair at the Library of Congress.
Citizen Clem
Bew’s biography of Clement Attlee, Citizen Clem: A Biography of Attlee, became his most celebrated book.
The work examined Attlee’s political career and his role in British history. It won the 2017 Orwell Prize for Books, with the Orwell Foundation describing it as a major work of political biography.
King’s College London states that Citizen Clem won three national awards, including the prestigious Orwell Prize.
John Bew at the Library of Congress
A major milestone in Bew’s academic career came when he became the Henry A. Kissinger Chair in Foreign Policy and International Relations at the Library of Congress’s John W. Kluge Center.
He held the position during 2013–2014 and researched Anglo-American realpolitik. The Library of Congress identifies him as the thirteenth holder of the chair.
His research there contributed to his work on Realpolitik: A History. Bew later described the residency as an especially productive period in his academic career.
John Bew and British Government
In 2019, Bew entered government as Foreign Policy Adviser to the Prime Minister, working from No. 10 Downing Street.
His government career lasted more than five years and continued across successive administrations. According to King’s College London, he served through four prime ministers and two general elections before making his planned return to academia in October 2024.
His responsibilities placed him close to major decisions involving Britain’s foreign policy and national security.
Role in National Security Strategy
Bew played a major role in Britain’s recent national-security planning.
He led the No. 10 team responsible for the 2021 Integrated Review of Foreign Policy, Defence and Security and the 2023 Integrated Review Refresh. He also represented the United Kingdom on the NATO Secretary General’s Reflections Group, whose work contributed to NATO’s 2022 Strategic Concept.
His government work covered major international questions involving Britain’s relationships with allies and partners.
Work on International Relations
During his government service, Bew was involved with major international agreements and diplomatic initiatives. King’s College London records his involvement with subjects including AUKUS, the Global Combat Air Programme, Ukraine, NATO and Britain’s wider international strategy.
He also travelled with and represented the Prime Minister at major international meetings, including NATO, G7, G20 and United Nations General Assembly events.
His work therefore extended beyond traditional historical scholarship into practical diplomacy and national strategy.
Northern Ireland and John Bew
Northern Ireland has remained an important part of Bew’s professional background. As a native of Northern Ireland and a historian of British and Irish political history, he has brought particular expertise to questions involving the region.
During his government career, he was involved in discussions surrounding the Windsor Framework and the restoration of devolved government in Northern Ireland.
This aspect of his career demonstrates how his historical expertise could be applied directly to contemporary political challenges.
Awards and Recognition
John Bew has received significant recognition for both his scholarship and public service.
King’s College London records that he won the Philip Leverhulme Prize for International Studies in 2015. His biography of Attlee later brought further recognition, including the Orwell Prize and other national awards.
In 2025, Bew was appointed Commander of the Order of St Michael and St George (CMG) for services to British foreign policy.
Current Academic Work
After leaving his Downing Street position in 2024, Bew returned to academia. He continues as Professor of History and Foreign Policy at King’s College London.
He is also a distinguished visiting fellow at the Hoover Institution, a senior adviser at the Australian National College of National Security, and a fellow of the Royal Historical Society, according to his King’s College profile.
In 2025, he was also reappointed by the Labour government to lead work on the UK’s National Security Strategy 2025.
John Bew’s Influence on Foreign Policy
The most distinctive feature of John Bew’s career is the way he combines historical scholarship with practical statecraft.
Rather than treating history simply as a record of the past, Bew has promoted the idea that historical knowledge can help policymakers understand present challenges. King’s College London describes this approach as applied history.
His work demonstrates how the study of past leaders, wars, diplomatic settlements and political movements can contribute to modern debates about national interest and international strategy.
Legacy
John Bew’s professional legacy rests on two closely connected achievements. First, he has established himself as an accomplished historian, particularly through his books on British political figures, realpolitik and British-Irish history. Second, he has brought that historical expertise into the highest levels of British foreign-policy decision-making.
His career at King’s College London, his work at the Library of Congress and his years in Downing Street show an unusual movement between scholarship and government.
For readers interested in British history, international relations, diplomacy and modern statecraft, John Bew represents an important example of how historical research can influence contemporary public policy.
Conclusion
John Bew has built a distinctive career as a historian, author and foreign-policy adviser. His books have examined major themes in British political history, while his government work has placed him at the centre of important debates about Britain’s national security and international role.
From Castlereagh and Realpolitik: A History to his award-winning Citizen Clem, his scholarship has focused on leadership, statecraft and political decision-making. His later service in No. 10 Downing Street demonstrated the practical value of that expertise.
Today, Bew continues to combine academic research with international policy work. His career remains a strong example of how the study of history can inform the difficult foreign-policy choices faced by governments in the modern world.
