Red Flag
Origins and Historical Usage
The term "red flag" has a rich history, tracing its roots back to the medieval times. It was during this period that red flags were used in military contexts to signal the start of a conflict. The color red was chosen due to its high visibility and the association with danger and urgency.
In the 17th century, the red flag took on a new meaning in the maritime world. Ships in distress would raise a red flag to signal their need for assistance. This practice was widely adopted and is still in use today in various forms, such as the international maritime signal flags.
The 18th and 19th centuries saw the red flag becoming a symbol of defiance and revolution, particularly in Europe. During the French Revolution of 1789, the red flag was used as a symbol of martial law and a warning against revolt. However, it was during the Paris Commune of 1871 that the red flag became a symbol of the working class and the socialist movement.
