" This Star-Spangled Banner and all its successors have come to embody our
country, what we think of as America. It may not be quite the same for every
one of us who looks at it, but in the end we all pretty much come out where the
framers did. We know that we have a country founded on the then revolutionary
idea that all of us are created equal, and equally entitled to life, liberty,
and the pursuit of happiness." --Pres. William Jefferson Clinton, speaking
before the Star-Spangled Banner at the National Museum of American History, July
13, 1998.
              Flag
                      as Patriotic Symbol
  Key's song "The Star-Spangled Banner" did more than give the American
  flag a name; it changed the way Americans looked at their flag. In the early
  1800s, Americans, like people in other countries, considered a national flag
  simply a military or naval emblem. By the 1860s, the song "The Star-Spangled
  Banner" had become so popular and so closely associated with the stirring
  events of the Civil War that it elevated the flag to a special place in the
  hearts of Americans. Today the flag is the primary symbol of American patriotism.
              Flag
                      Design
  The design of the U.S. flag was derived from designs used for flags at the
  beginning of the American Revolution. On June 14, 1777, Congress declared the
  flag to be 13 alternating red and white stripes with a union of 13 white stars
  in a blue field. In 1794, after Kentucky and Vermont joined the Union, Congress
  added two stars and two stripes. In 1818, when five more states had joined,
  Congress again changed the design to 13 stripes, representing the original
  13 states, and 20 stars, with a provision that an additional star be added
  on the admission of each new state.
              Although
                  popular tradition has invested the colors of the flag with
                  symbolism--red for valor, white for liberty or purity, and
                  blue for justice, loyalty, and perseverance--there is no document
                  that historians can point to that gives this symbolism official
                  standing.
              The
                    design and colors have been the basis for a number of other
                    flags including Chile, Liberia, Malaysia, and Puerto Rico
