The Flag of the United States, often called the "Stars and Stripes," features thirteen horizontal stripes in red and white, representing the original thirteen colonies. In the top left corner, there is a blue rectangle with fifty white stars, symbolizing the fifty states of the union. The flag's design has evolved since its adoption in 1777, with stars added as new states joined. The colors of the flag also hold significance: red represents valor and bravery, white symbolizes purity and innocence, and blue stands for vigilance, perseverance, and justice. The flag is a powerful symbol of American identity and unity, often displayed during national holidays and events.
