The Navajo Code Talkers were Navajo Marines in World War II who used their Indigenous language to create and transmit an unbreakable military code for U.S. forces in the Pacific.

Who they were

  • The first group was a specially recruited team of 29 Navajo men in 1942 who developed the original code at the request of the U.S. Marine Corps.
  • Over time, the program grew to roughly 400 Navajo Marines trained as Code Talkers, making it the largest Native American code-talking unit in the U.S. military.

What they did in WWII

  • They created a code based on Navajo words, inventing more than 200 new terms to stand in for military phrases, equipment, and tactics, all memorized instead of written down.
  • In combat, they sent vital messagesā€”like troop movements and calls for artillery supportā€”much faster and more accurately than existing encryption methods, and enemy forces never broke their code.

Why Navajo language was ideal

  • Navajo was then an unwritten, complex language spoken by relatively few people, making it extremely hard for enemy codebreakers to study or imitate.
  • The code layered extra substitutions on top of everyday Navajo words, so even a fluent Navajo speaker who did not know the system would not automatically understand the messages.

Secrecy and later recognition

  • Their work was classified as ā€œtop secret,ā€ and for about 25 years after the war they were ordered not to talk about what they had done, even with family.
  • The program was declassified in 1968, and in later decades Code Talkers received official honors and public recognition, including a U.S. day of observance, Navajo Code Talkers Day, on August 14.

Legacy and today

  • Historians credit the Code Talkers with helping U.S. forces succeed in key Pacific battles by securing communications and speeding battlefield decisions.
  • Their story now appears in museums, oral history projects, and public discussions as a powerful example of how an Indigenous language and community contributed to global events in the twentieth century.
