Facts about the flag:
The flag of the United States, also known as "Stars and Stripes" or the "The Star-Spangled Banner" from the national anthem, received its name from all the stars and stripes figuring on the flag. The 50 stars represent the current 50 states in the US and the 13 stripes remind us of the original US states.
The latest appearance of the flag was created and adopted on July 4, 1960.
The flag's main pattern was established during the Freedom War, but has changed 26 times since then. The reason for these changes is due to a new star being added for each new state in the United States. Originally, a new stripe was supposed to fill that part, but it was thought by some that the growing number of stripes would eventually destroy the design of the flag.
In 1818, congress decided that there would be only 13 stripes and that one star would be added for each new state. There are no previous rules on how the stars would be placed on the flag. However, nowadays it is determined by the regulation of the president. If a new state is created, a star will be added on the 4th of July - the Independence Day of the United States.
