The Flag Resolution of 1777 authorized the first official design of the United States national flag. Since that time, the flag has undergone 26 changes, all of which have altered the star portion of the flag to represent the number of states in the Union. Originally, there was no elaborate symbolism attached to the flag's colors. Meanings were assigned later, in 1782, when Charles Thomson gave a report to Congress defining the new Great Seal of the US. What do the colors now represent?
