Today is Flag Day.

On this date in 1777 - 233 years ago - the Second Continental Congress in Philadelphia adopted the stars and stripes as the flag of the United States.

Flag Day is not a federal holiday.

But commemorations of the day date back to 1916, when President Woodrow Wilson issued a proclamation establishing June 14 as Flag Day.

Philadelphia's Betsy Ross is perhaps the nation's best known flag maker, but historians say the story of her involvement in the creation of the U.S. flag is more legend than fact.

But Ross, who was Elizabeth Claypoole when she died in 1836, did help supply the nation with flags in post-Revolutionary America from the shop she operated with her daughters.
