Smoke communication dates back to ancient times, with evidence of its use by various cultures over thousands of years. The most notable early systems were developed by the Indigenous peoples of the Americas and the ancient Greeks. The Greeks are often credited with creating a more structured method around 400 BCE, using smoke signals for military communication. However, the exact time of its invention is difficult to pinpoint, as different cultures likely developed similar methods independently.
