A new constellation
The Continental Congress adopted the flag in a single sentence. It did not say how the stars should be arranged, how many points they should have or what the colors meant, so early flags came in many patterns, from circles of stars to rows and scattered designs.
Who designed it is still debated. Francis Hopkinson, a New Jersey signer of the Declaration of Independence, later asked Congress to pay him for his flag design work. Tradition credits the Philadelphia upholsterer Betsy Ross with sewing the first flag, a story her grandson William Canby made public in 1870. Historians have not settled the question, and the flag belongs to everyone who has served under it.
The colors had no official meaning in 1777. When Congress approved the Great Seal in 1782, its secretary, Charles Thomson, explained that white signified purity and innocence, red hardiness and valor, and blue vigilance, perseverance and justice. Americans have read those meanings into the flag ever since.
