British politician Daniel Hannan's Inventing Freedom is an ambitious account of the historical origin and spread of the principles that have made America great, and their role in creating a sphere of economic and political liberty that is as crucial as it is imperiled.

According to Hannan, the ideas and institutions we consider essential to maintaining and preserving our freedoms--individual rights, private property, the rule of law, and the institutions of representative government--are the legacy of a very specific tradition that was born in England and that we Americans, along with other former British colonies, inherited.

By the tenth century, England was a nation-state whose people were already starting to define themselves with reference to inherited common-law rights. The story of liberty is the story of how that model triumphed. How it was enshrined in a series of landmark victories--the Magna Carta, the English Civil War, the Glorious Revolution, the U.S. Constitution--and how it came to defeat every international rival.

Today we see those ideas abandoned and scorned in the places where they once went unchallenged. Inventing Freedom is a chronicle of the success of Anglosphere exceptionalism. And it is offered at a time that may turn out to be the end of the age of political freedom.
