Political theorist Thom Hartmann uncovers the lesser-known history of American gun ownership and how the Second Amendment has been a constant force in shaping the nation.

Guns have been a part of American history since the first European settlers arrived in the 15th century with muskets.

With the highest gun ownership per capita worldwide, the U.S. has long had a serious gun problem.

The Hidden History of Guns and the Second Amendment is a book by political theorist and radio personality Thom Hartmann about the legacy of guns in American history.

Hartmann shows how guns enabled slavery, westward expansion, and the incredible surge in the American prison population, as well as how the National Rifle Association, keeps gun rights and sales as free as possible.
