The Cousins' War
The Cousins’ War by Kevin Phillips ties the English Civil War to the American Revolution and then to the Civil War. The thesis is that with every turn of the English war (1642 to 1648) and every turn of politics, another set of dissidents was shaken out of England. The Parliamentarians tended to go to New England, the Royalists to Virginia. Their attitudes tended to persist, the North being more democratic than the South.
