This book investigates the historical origins of the Second Amendment to determine whether the Founding Fathers intended to protect an individual right to bear arms or a collective right tied to militia service. Saul Cornell, a professor of history and expert on early American constitutionalism, utilizes a vast array of primary sources—including legislative debates, court cases, and political pamphlets—to reconstruct the original public meaning of the amendment. He argues that the modern debate over gun control is a product of evolving legal interpretations rather than a static historical consensus. By tracing the evolution of militia laws from the Revolutionary era through the Antebellum period and the Fourteenth Amendment, Cornell provides a rigorous framework for understanding how the right to bear arms was historically balanced against the need for public order.

Legal scholars and historians frequently cite this work as a foundational text for understanding the historical complexity of the Second Amendment. Readers often note the academic density of the prose, which demands a high level of engagement with the provided legal and historical documentation.
