Allen Guelzo Revisits a Forgotten Fight for Freedom

Constitution
Thought Leader: Allen Guelzo
September 17, 2026
Written by: Allen Guelzo

In a recent Gettysburg Times commentary, WWSG speaker and acclaimed historian Allen Guelzo, writing with Michael D. Jahr, revisits the remarkable story of Joshua Glover, an escaped enslaved man whose fight for freedom became a significant test of the Constitution in the years before the Civil War. Glover escaped slavery in Missouri and made his way to Wisconsin, where his arrest under the Fugitive Slave Act ignited public resistance and a legal battle over federal authority, individual liberty, and the constitutional obligations of the states.

Guelzo and Jahr use Glover’s largely forgotten story to illuminate a larger question about the durability of the American constitutional system. They argue that the Constitution has endured not simply because it established the structure of American government, but because it created mechanisms through which Americans could challenge injustice and continue working toward the promise of “a more perfect Union.” Glover’s experience offers a powerful historical example of the tensions embedded in the nation’s founding framework and the role citizens, courts, and political institutions have played in confronting them.

An award-winning historian and bestselling author, Allen Guelzo brings American history to life while connecting the defining debates of the past to questions that continue to shape the country today. His scholarship and storytelling offer audiences a deeper understanding of American history, the Constitution, leadership, and the ideas that have shaped the nation.
