National symbols are important representations of a country's identity and values. Flags are one of the most common national symbols, and they are typically composed of a design, pattern, or color scheme that is unique to a particular nation. Flags are often flown at public events, such as sporting events, parades, and political rallies, and they are also used to represent a country in international forums. Flags can also be used to show support for a cause or to commemorate a special event.
