The United States flag, often referred to as the American flag, is a powerful symbol of the country's history and values. The flag features thirteen horizontal stripes, alternating between red and white, and a blue rectangle in the canton with fifty white stars. The stars represent the fifty states of the United States, while the stripes symbolize the original thirteen colonies that declared independence from Great Britain. The flag is a ubiquitous presence in American life, flown outside government buildings, schools, and homes across the country. It is also a popular symbol of American culture and identity, often displayed at patriotic events and celebrations. The flag's design has undergone several changes since its adoption in 1777, with the number of stars and stripes adjusted to reflect the country's growth and expansion.
