When William Freehling's Prelude to Civil War first appeared in 1965 it was immediately hailed as a brilliant study of the origins of the American Civil War. Three decades later, its importance remains undiminished and is still considered one of the most significant studies in its field. This vivid description of a society on the brink powerfully conveys the combustive social elements of the Old South, as well as the political manoeuvring and combative personalities that finally ensured secession and war, and insists upon the central importance of the South's `peculiar institution' in understanding the roots of the Civil War.
