A New Podcast Series
Before It Became History, a podcast series from the Sandra Day O’Connor Institute, explores the people and moments that shaped the American story. Each episode looks beyond the legend to examine the decisions, conflicts, and ideas that tested the promise of liberty and helped define our democracy.
Before they were names in history books, they were organizers, poets, spies, diplomats, soldiers, and citizens making impossible choices in uncertain times.
Before they were events we study and reference today, they were the stories shared between neighbors, written about in newspapers, or broadcast over the radio and eventually television.
This is history before it hardened into memory — and a conversation about what it means for us now.

The Untested Shortcut: Lansford Hastings and the Donner Party

The Compromise of 1850: Five Laws, One Unraveling Peace

The Oregon Treaty of 1846: Stepping Back from War

Narcissa Whitman:The Letters That Made Oregon Imaginable
