What do the stars on the U.S. flag represent?

The stars on the U.S. flag represent the states in the union. Each star symbolizes one of the 50 states, reflecting the unity of the states within the country. The design of the flag has evolved over time as new states were admitted into the union, with a new star added for each state. This element of the flag emphasizes the idea of federalism and the collective identity of the states that make up the United States, showcasing their equal status in the nation. By representing the states, the stars also serve as a reminder of the country's democratic foundations, where each state has a voice in the federal government system.
