John Quincy Adams is one of those figures who seems to sit quietly in the background of American history — the son of a Founder, a one-term president, a man often overshadowed by bigger personalities. But look closer, and a very different story emerges. After losing the presidency, Adams didn’t fade away. He reinvented himself. He returned to Washington, entered the House of Representatives, and became one of the most relentless and morally uncompromising voices of his generation — especially on slavery.

In his new book America’s Founding Son: John Quincy Adams from President to Political Maverick, Bob Crawford argues that Adams may not just be an important former president — he may be the most consequential ex-president in American history. This is a story about failure, reinvention, and what happens when someone freed from ambition becomes dangerous in the best possible way. It’s also a story about a nation moving from the age of the Founders toward the sectional crisis that would eventually tear it apart.

Today, we talk with Bob Crawford about Adams’s second act, his evolving stance on slavery, his battles in Congress, and why this supposedly minor president might actually be one of the most important political figures of the nineteenth century. We’ll also explore what Adams can teach us about political courage, moral conviction, and the long arc between the American Revolution and the Civil War.

This is a conversation about John Quincy Adams — but it’s also a conversation about what it means to lose power… and finally tell the truth.
