Russell became a historian working on the origins of the
English Civil War and critical of older
Whig and
Marxist interpretations. His major works include
Crisis of Parliaments: English history 1509–1660 (1971),
Origins of the English Civil War (edited, 1973),
Parliaments and English politics, 1621–1629 (1979),
Unrevolutionary England, 1603–1642 (1990), and
Fall of the British monarchies, 1637–1642 (1991). His work on early Stuart Parliaments was profoundly influenced by the work of Alan Everitt, who had argued that the English gentry were preoccupied with defending their positions in the localities rather than responding to the demands of the Crown. This no longer seems entirely plausible in the light of the work done by Richard Cust, Clive Holmes, Peter Lake and Christopher Thompson. Russell argued that the Civil War was much less a result of long term constitutional conflicts than had previously been thought, e.g. by
Lawrence Stone and
Christopher Hill, and that its origins are to be sought rather in the years immediately preceding the outbreak of war in 1642 and in the context of the problems of the multiple kingdoms of the British Isles, a hypothesis for which he was indebted to the pioneering study of
Helmut Koenigsberger. This area is still being explored by historians like John Adamson and David Scott even if their detailed conclusions vary from those reached by Russell. He was lecturer (and later
reader) in history at
Bedford College,
University of London (now part of
Royal Holloway), 1960–1979; professor of history at
Yale University, US, 1979–1984; Astor Professor of British History at
University College London, 1984–1990; and professor of British history at
King's College London from 1990 to his retirement in 2003. ==Political career==
