In fact, it wasn’t until 1938 that it became a paid day-off. So how did the Fourth become the holiest day on our secular calendar? This episode offers some answers. With perspective from guests and taking questions from listeners, Peter, Ed, and Brian explore the origins of July Fourth. They highlight the holiday’s radical roots, look at how the Declaration’s meaning has changed over time, and consider how the descendants of slaves embraced the Declaration’s message of liberty and equality.
