He was Professor of Medieval History, University of Liverpool (1945–1956) during which period he lived in the Seneschal's House, Halton Village, Stevenson Research Professor, University of London (1956–1962), University of California (1965–1968) and Professor of History, Brandeis University (1968–1970 and 1972–1981). He was Chichele Professor of Modern History, University of Oxford from 1970 to 1973.
During the Second World War, Barraclough's sympathy for the USSR and public opposition to the Warsaw Uprising of 1944 drew the criticism of George Orwell, among others.
Professor Barraclough began his career as a medievalist, but developed into a contemporary global historian. He was deeply concerned about history's uses and relevance in the 20th century. It seemed to him that political debate and ultimately political decisions, suffered from a lack of historical insight. To rectify this problem Barraclough developed historiographical methods for comparative history.
By anchoring study of the past at the origins of a historical investigation, while simultaneously researching contemporary areas most directly connected to that anchor research, his methods established comparisons between past and present. With this two-pronged research structure, Barraclough was able to organize his investigations by looking from the past forward and from the present backwards. He sought historical threads that connect past to present while also observing the discontinuities that separate past from present.
In his writing, Barraclough turned to geography, social and economic cycles, empires, trade and tribes as historical units he felt most clearly connect past to present or combine to end that continuity. Using these methods allowed him to sketech an outline of world history, identifying its ups, downs and turning points.
His first two books on historiography, History in a Changing World and An Introduction to Contemporary History are collections of essays. With scholarly authority, Barraclough served as editor of The Times Atlas of World History, which continues to be revised.
