John Stephen Morrill (born 12 June 1946) is a British historian and academic who specialises in the political, religious, social, and cultural history of early-modern Britain from 1500 to 1750, especially the English Civil War. He is best known for his scholarship on early modern politics and his unique county studies approach which he developed at Cambridge. Morrill was educated at Trinity College, Oxford, and became a fellow of Selwyn College, Cambridge, in 1975. Morrill was born on 12 June 1946 to William Henry Morrill and Marjorie (née Ashton). He was educated at Altrincham County Grammar, an all-boys grammar school in Cheshire. In 1964, he matriculated into Trinity College, Oxford, to study history. He graduated with a Bachelor of Arts (BA) degree in 1967, and a Doctor of Philosophy (DPhil) degree in 1971. Morrill began his academic career with a number of short term appointments. For the 1970/71 academic year, he was Keasbey Lecturer in history at Trinity College, Oxford. He held a junior research fellowship at Trinity from 1971 to 1974. He was also a college lecturer in history at St Catherine's College, Oxford, for the 1973/74 academic year. Then, from 1974 to 1975, he was a lecturer in modern history at the University of Stirling. Although his Stirling post had been a permanent appointment, Morrill moved to the University of Cambridge in 1975, having been appointed an assistant lecturer (later lecturer) in its Faculty of History. He was promoted to reader in early modern history in 1992, and professor of British and Irish history in 1998. He was deputy director of the Centre for Research in the Arts, Social Sciences and Humanities (CRASSH) from 2001 to 2004. He has also been a fellow of Selwyn College, Cambridge, since 1975 and active in the college's administration: he was director of studies in history from 1975 to 1992, a tutor from 1979 to 1992, admissions tutor from 1982 to 1987, the senior tutor from 1987 to 1992, and served as vice-master from 1992 to 2001.
