This chapter covers the period between the years 1649 and 1653. It was during this time when England embarked on a revolution — the real ‘first modern revolution’ — with profound and permanent consequences. This would involve a jarring process of change, over two generations, in the course of which the institutions, administration, power-structures, and policies of English government were remade to be capable of competing with their Dutch model. That model was not only political, military, and economic but also religious, cultural, and moral. From the Dutch the English republic would take the post-dynastic policies, and the fiscal and administrative practices, of a modern, mercantile, and Protestant free state. These would be applied to the construction of a state and empire which were, or became distinct, by measures directed in the first place against the competing economic pretensions of the Dutch themselves.
