The iconic U.S. flag, affectionately known as "the Stars and Stripes" or "Old Glory," features 50 white stars representing the states and 13 alternating red and white stripes symbolizing the original thirteen English colonies. Not designed by any single individual, this evolving symbol gained immense national prominence during the American Civil War, especially after the 1861 attack on Fort Sumter, solidifying its role as a powerful emblem of the Union. The Union victory cemented its status as a national flag, leading to its current worldwide recognition as a symbol of the United States. The 50-star design, the 27th official version, was adopted in July 1960 following Hawaii's admission, making it the longest-used flag in U.S. history.
