ABSTRACT This article contrasts Francis Bacon’s understanding of civil war, sedition, and rebellion with that of his near contemporaries and predecessors, especially Montaigne, Bodin, Machiavelli, Alberico Gentili and Edward Forset. The article contends that for Bacon, civil war, sedition, and rebellion are the antitheses of good government and that which prudent policy aims to avoid. The article further argues that for Bacon as sedition and its extremities are caused by poverty and discontentment, and these, in Bacon’s view, are the result (...) of overpopulation or ‘surcharge of people’, Bacon’s view for the avoidance of civil war aims at policies of outward expansion in the form of colonies and wars of aggression, both of which aim to reduce the metropole’s own population and therewith its propensity to civil war. The article argues that a consideration of Bacon on civil war in particular will shed considerable light on the ideological origins of the British Empire which have often been ignored – where some contemporary political theorists and historians are keen to link ideologies of empire to corresponding positions in political anthropology. A consideration of Bacon’s thought on civil war will show, instead, the article contends, that for key ideological originators of imperial justifications, imperial projects have their origin in domestic politics and the avoidance of civil war.
