A nation’s flag is not merely a piece of cloth used to identify a country or mark territory. It also allows people with a shared culture to celebrate what unites and represents them. In other worlds, flags matter — which may help explain why the American flag has gone through no fewer than 27 iterations over the last 247 years. In fact, the United States holds the world record for the most changes to a national flag, as the design was continuously updated as the country expanded and more states were added to the union.
