How the Post Office Created America: A History by Winifred Gallagher (2017)

A masterful history of a long-underappreciated institution, How the Post Office Created America examines the surprising role of the postal service in our nation’s political, social, economic, and physical development. The founders established the post office before they had even signed the Declaration of Independence, and for a very long time, it was the U.S. government’s largest and most important endeavor—indeed, it was the government for most citizens. This was no conventional mail network but the central nervous system of the new body politic, designed to bind thirteen quarrelsome colonies into the United States by delivering news about public affairs to every citizen—a radical idea that appalled Europe’s great powers. America’s uniquely democratic post powerfully shaped its lively, argumentative culture of uncensored ideas and opinions and made it the world’s information and communications superpower with astonishing speed.
