History in a 5×5

During the American Revolution, the Continental Congress adopted a resolution stating that “the flag of the United States be thirteen alternate stripes red and white” and that “the Union be thirteen stars, white in a blue field, representing a new Constellation.” The national flag, which became known as the “Stars and Stripes,” was based on the “Grand Union” flag, a banner carried by the Continental Army in 1776 that also consisted of 13 red and white stripes.

1949 Congress officially designated June 14 as Flag Day, a national day of observance.
