National flags are symbols that represent countries and their values. Each flag has unique colors, patterns, and designs that often reflect the nation's history, culture, and beliefs. For example, the United States flag features red, white, and blue stripes, symbolizing bravery, purity, and justice. Flags are displayed during national holidays, events, and ceremonies, fostering a sense of pride and unity among citizens. Flags also play a significant role in international relations. They are used in diplomatic settings, such as at the United Nations, where countries gather to discuss global issues. Additionally, flags are flown during sporting events, like the Olympics, showcasing national pride and encouraging friendly competition among nations.
