To understand the Constitution of the United States, one must study the history of England, especially the Stuart era. The original Bill of Rights, the Habeas Corpus Act of 1679, and other immediate progenitors of provisions of our Constitution come from that era. In the WSJ, historian William Anthony Hay has this review of "1688: The First Modern Revolution," by Steve Pincus. Hay and Pincus disagree on the extent to which the Glorious Revolution was blazing a new trail versus rescuing old traditions from recent usurpations.
