Flag semaphore was popular primarily in the 19th century and into the early 20th century, particularly for naval communication and signaling. Its use peaked during the age of sail and continued into the era of steamships, before being largely supplanted by radio and other forms of communication technology. While its practical use declined significantly after World War I, flag semaphore is still taught and used in certain contexts today, such as in maritime training and some recreational activities.
there are 28 semaphore flag methods.

The semaphore flag signaling system was developed by Claude Chappe in France during the late 18th century. Chappe's system used a series of different flag positions to convey messages over long distances, and it was widely used for communication before the invention of the telegraph.
It is a semaphore. They use flag signals to communicate with other ships.
It is called "Semaphore code".
It was invented in France. It was popular in the late 18thC
You would use the alphabet of the semaphore flag signaling system. See the related link for the picture of signals.
Semaphore was invented as a visual signaling system to relay messages over long distances. It was developed to communicate with ships at sea or between different points on land where other methods of communication like smoke signals or flags were not practical. Semaphore systems used different flag positions to represent different letters or words and were widely used before the invention of the telegraph.
Yes, semaphore is still in use today, particularly in maritime and railway signaling. In maritime contexts, flag semaphore is used for visual communication between ships, while in railways, semaphore signals help manage train movements. Although modern technologies like electronic signals and radio communication have largely replaced semaphore in many areas, it remains a valuable skill in specific situations and industries.
It is the flag-semaphore signal for N and the symbol for D put together...standing for nuclear disarmament.
Morse code is an audio code (or blinking light code), it has nothing to do with flags.When flags are used to send messages, this is called semaphore, so they would be "semaphore flags".See the related links below.
