A 21-gun salute is a ceremonial act that involves firing 21 cannons or guns in a specific sequence. This tradition is often used to honor important figures, such as heads of state or military leaders, during state funerals, national holidays, or significant events. The salute symbolizes respect and recognition. The practice dates back to the 14th century and has evolved over time. It is commonly performed by military units and is recognized internationally as a mark of honor. The number 21 was chosen because it is considered the highest number in the traditional salute system, making it a powerful gesture of tribute.
