How One Battle Near Brownsville, Texas Won America the West Coast

Most people have never heard of the Mexican-American War — but it gave the United States everything from New Mexico and Arizona to California. And it all started right here, on a quiet coastal prairie near Brownsville, Texas. Join Susan and Monica as they dig into one of the most underrated — and most important — National Park Service sites in the entire country: Palo Alto Battlefield National Historical Park.

We're talking about the war that literally completed the map of America, the only NPS site dedicated to preserving where it started, and the surprisingly moving story of thousands of people who became U.S. citizens overnight just because someone drew a new border. Plus — what the heck IS the difference between a National Historic Site and a National Historic Park? Susan explains it all.
