The American flag, also known as 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 United States. The flag's colors have specific meanings: red stands for valor, white for purity, and blue for justice. The flag is a national symbol and is often displayed during patriotic events, such as Independence Day and Memorial Day. It is also used in military ceremonies and is a common sight at government buildings. The flag's design has evolved since its first adoption in 1777.
