A History of Britain by Simon Schama

In the aftermath of Civil War, Britain was a kingless republic led by Oliver Cromwell. Cromwell ruled with an iron hand; when Parliament dared defy him, he marched in and closed it down. He ruled as king in all but name, with his Major Generals imposing Godly Puritan rule on the counties. The anarchy that prevailed at his death led to the Restoration of Charles II, who survived the Great Fire and a dynastic crisis triggered by anti-Catholic paranoia. James II's Catholic fervour threatened to trigger another revolution; he was deposed by the troops of the Dutch King William.
