To many seventeenth century observers, the political role of towns in the English Civil War was clear enough. Clarendon, for example, referred to the “great towns and corporations, where besides the natural malignity, the factious lecturers and emissaries from the Parliament had poisoned the affections.” Thomas Hobbes was even more specific: “The City of London and other great towns of trade, having in admiration the prosperity of the Low Countries after they had revolted from their monarch the king of Spain were inclined to think that the like change of government here would to them produce the like prosperity.” In similar fashion, the anonymous author of the 1648 tract Persecutio Undecima saw the commercial interests of the urban areas, especially London, as one of the significant factors in the calling of the Long Parliament and the subsequent outbreak of war.
