What factors led the American people to think of this flag as an important historical artifact?

The stripes represent the original 13 Colonies and the stars represent the 50 states of the Union. The colors of the flag are symbolic as well; red symbolizes hardiness and valor, white symbolizes purity and innocence, and blue represents vigilance, perseverance and justice. Our flag is an inspiring symbol that unites us all as American citizens. The unique history of the American flag follows the history of our country and reminds us of the triumphant beginning of the United States. The 13 stripes: a symbol of the first 13 colonies. The stars: a symbol of our country's 50 United States. As our country grew and developed, so did our flag. It has followed the fate of the country itself and, in the future, our flag may even change again.
