National Navajo Code Talkers Day

National Navajo Code Talkers Day, observed annually on August 14th, honors the Navajo Marines who developed and used a code based on their native language to transmit secure military communications during World War II, a code that Japanese cryptographers never managed to break. Recruited beginning in 1942, the original group of 29 Navajo Marines created a specialized code by assigning Navajo words to represent military terms and using the complex, largely unwritten Navajo language itself as an additional layer of security, since it was virtually unknown outside a small population of fluent speakers and had no written alphabet at the time. The code talkers served in every major Marine engagement in the Pacific Theater, including the pivotal Battle of Iwo Jima, where Major Howard Connor, signal officer for the Fifth Marine Division, later stated that the Marines could not have taken the island without the code talkers, whose transmissions helped coordinate critical troop movements and artillery strikes with speed and total security. Despite their crucial wartime contributions, the code talkers' work remained classified for over two decades after the war ended, meaning many received no public recognition for their service until the program was declassified in 1968. In 2001, President George W. Bush awarded the Congressional Gold Medal to the original 29 code talkers, with additional Navajo code talkers who served later in the war receiving the Congressional Silver Medal. National Navajo Code Talkers Day is observed with ceremonies honoring their legacy, educational programs on their contributions, and recognition events within Navajo Nation and across the broader United States.
