Roe v. Wade to the present

Lavin Exclusive Speaker

This is a crucial moment in our democracy: our courts and politics are divided, and the binding trust that we place in our institutions is fast eroding. But historian Mary Ziegler says that, by understanding our Constitution and its effects on our lives, we can move beyond polarization to achieve a better dialogue and fairer future for all. Widely hailed as a nonpartisan authority on the Constitution and in particular the legal history of reproductive rights, Mary is a professor at UC Davis School of Law, the award-winning author of seven acclaimed books, and a frequent contributor to The New York Times and The Atlantic. She has advised governors and members of Congress, submitted congressional testimony, and been covered by outlets including PBS, CNN, MSNBC, and The Washington Post.

Our Constitutional StoryWomen and the American Constitution

For two hundred and fifty years, women have been central to America’s constitutional experiment. Their contributions have far-reaching implications for the story of our past—and of our future.

In this talk, constitutional scholar Mary Ziegler traces women’s contributions to our Constitution from 1776 to the present. It’s a story of rights gained and lost—and about how women mobilized to make sure the rights they gained applied to everyone, and delivered more than an empty promise. From women’s struggle for personhood in marriage and suffrage to the fights over sexual violence, equal pay, civil rights, and the loss of the right to abortion, Mary shows how women have been central to America’s constitutional story, and she reminds us what these women never forgot: that securing constitutional rights is only the first step to the equality that all women deserve.

Canary in the CoalmineWhat It Means to Lose a Constitutional Right

The reversal of Roe v. Wade, the landmark Supreme Court decision to protect the right to choose abortion, is about much more than reproductive rights. At its heart, it’s about the rise of a conservative legal movement, the transformation of Supreme Court nominations, the fundamental changes in the U.S. Republican Party, and the rise of extreme polarization. What does this decision mean for our democracy or the Court’s legitimacy?

As a preeminent expert on the legal and political history of our constitutional rights, lawyer and historian Mary Ziegler is uniquely situated to answer these questions and guide us through this turbulent topic. Understanding what happened to Roe v. Wade shines a light on broader issues of partisanship and the erosion of democratic norms in the United States—but it’s not too late to regain control of our democracy and restore our trust in the justice system.

A Nation DividedWhat Can We Do About American Polarization?

Polls show that American voters are mostly in agreement about abortion, but legal and political debates continue to rage from the right to the left—and that’s just one of the many current issues that divide us. How did we get to this point, and how can we recover?

Legal historian Mary Ziegler points to the fact that we haven’t always been this divided, which means that we can still take responsibility for our conflicts and work together for a better future. With insights from her prominent legal history research, she investigates the causes and effects of our deepening political rifts. She guides us to an understanding of where our current debates come from, and how we can rebuild a kinder and more nuanced dialogue around the law, the justice system, and our fundamental rights.
