Thirteen stars represent the original colonies: Delaware, Pennsylvania, New Jersey, Georgia, Connecticut, Massachusetts Bay, Maryland, South Carolina, New Hampshire, Virginia, New York, North Carolina, and Rhode Island and Providence Plantations. Stars were added to the flag as states were added to the country.
The thirteen stripes also represent the thirteen British colonies that declared independence from the Kingdom of Great Britain and became the first states in the United States. Legend attributes the red on white as symbolism for blood on white bandages.
