Though this was intended to be a fairly straightforward and comprehensive look at England in the 17th century, almost a textbook really, it is surprisingly readable. Coward focuses on the monarchs (both Jameses, both Charleses, William and Mary, and Anne) and the Cromwellian interregum, and on how the long battles over finances and religion between the executive and the parliament continued throughout this period, which provides a fairly linear, though complicated, narrative to follow.
Coward makes a strong case for consistency in conflict between king (or Cromwell) and parliament throughout. James's and Charles's attempts to tax customs without statutes and to extort "ship money" assessments from inland counties, leading to parliamentary protests, were mimicked in the post-Civil War period by parliament's demands in the second Dutch War (1664-1667) to force on Charles II a royal commission to examine public accounts and their specifying for the first time how sums appropriated should be spent. The conflict was seemingly eternal.
Still, Coward shows that while fiscal and constitutional issues dominated the first 40 years of Stuart control, religious issues, especially fear of Catholicism, dominated the latter period. This anti-catholic paranoia was sparked by the revelation that Charles's son, the future James II, was a Catholic, demonstrated by his stepping down from a government post after the passage of the Test Act of 1673, which barred Catholics from office. After that, no parliament could fully trust the king and his heirs.
Coward shows how different early modern English "government" was from our own, so much so that he thinks that "government" is an inappropriate term for the variety of informal powers and mechanisms extending outward from the king's court. For instance, in the early 17th century, 40% of all the kingdom's budget was spent on the king's household itself. In this context, any debate about government "policy" was almost beside the point. All that money, the debate over which lead to such strife, mainly went to rich clothes and rich nephews.
There is admittedly a lot frustrating about this book. Like almost all English historians, including those who are supposedly writing straightforward, introductory texts, Coward assumes ready knowledge of things like the Cockney scheme or the Duke of Buckingham (though he doesn't go into it much, he was James I most intense male love), and this can be extremely irritating. The number of names, which often are changed with changing peerage placements, is simply impossible to follow, especially when so much is assumed to be common knowledge. Still, much of this text is thankfully easy to follow, and after finishing I finally feel like I understand a bit about this fascinating and chaotic age.
