Flags have served as symbols of identity, communication, and history for thousands of years. This episode explores how flags developed from military standards into national symbols, why they use particular colors and designs, and the traditions and rules surrounding their display. Along the way, you’ll hear about maritime signaling, vexillology, and the many roles flags have played throughout history. It’s steady and consistent, with no whispering and no sudden changes, just enough to give your mind something to follow as you wind down. Happy sleeping!
