On what date did the U.S. Congress create the flag?

The correct answer is June 14, 1777, because this is the date when the Second Continental Congress officially adopted the "Stars and Stripes" as the national flag of the United States. The resolution stated that the flag would consist of thirteen stripes, alternating red and white, and that the union would contain thirteen stars, representing the thirteen original colonies.

The significance of this date lies in its establishment of a national symbol that would unify the states during the American Revolution and serve as a representation of the nation's ideals and independence. The flag has since evolved, but this adoption marks a critical moment in American history, symbolizing the sovereignty and identity of the United States.

The other dates presented do not correspond to the official adoption of the flag. June 4, 1776, is associated with the debates leading to the Declaration of Independence, and July 4, 1776, marks the signing of that important document. April 15, 1775, is before the flag's adoption and does not hold any significance regarding the flag itself. Therefore, the selection of June 14, 1777 as the date of creation highlights a specific and significant event in the foundation of the United States and its symbolism.
