Thirteen stripes and a changing constellation
The United States flag keeps thirteen stripes for the original colonies while the number of stars has changed as states joined the Union. The current design has fifty white stars on a blue canton, one for each state.
Executive Order 10834 established the present fifty-star design after Hawaii became a state. It took effect on 4 July 1960. The stars and stripes therefore record different stages of the country's formation.

About historical flags
Vexilla's historical flag collection includes former flags associated with present-day countries and territories, as well as flags of states, empires, and other authorities that historically governed them.
A flag's inclusion in a country's historical collection does not necessarily mean that the country was independent at the time or that the flag was its own national flag.
The years shown are based on historical records in the dataset and do not always indicate the date of official adoption. The collection is not exhaustive, and historical usage, territorial coverage, and interpretations may vary.
