When religious passion gave way to the equally consuming passion for profits, it became possible for the pieces of Britain to come together as the spectacularly successful business enterprise of "Britannia Incorporated." And in a few generations that business state expanded in a dizzying process that transformed what had been an obscure, off-shore footnote to Europe's great powers into the main event - the most powerful empire in the world.

Yet somehow, it was the "wrong empire." The British considered it a bastion of liberty, yet it was based on military force and the enslavement of hundreds of thousands of Africans. In America, the emptiness of British claims to protect "freedom" was thrown back into the teeth of colonial governors and redcoat soldiers, while the likes of Sam Adams and George Washington inherited the mantle of Cromwell.
