Betsy Ross was from the major colonial city of Philadelphia.
A post-Revolutionary version, this official 1795 flag flew from Fort McHenry, inspiring Francis Scott Keyâs âStar-Spangled Banner.â. Marines raise the flag on Iwo Jima, perhaps the icon of World War II. Americans love the story of Betsy Rossâs making the nationâs first official flag. For almost 140 years now, the tale of the plucky, practical Philadelphia seamstress has occupied a comfortable niche in the countryâs patriotic pantheon alongside the stories of Paul Revere, the Minutemen, and Valley Forge.
