<human>:  What is the history behind the American flag?
<bot>: The American flag was adopted by the Second Continental Congress on June 14, 1777 and is a symbol of the United States of America. It has thirteen red and white stripes representing the original thirteen colonies and fifty stars for the fifty states. The stars are arranged in nine rows of six stars each and one row of five stars. The flag has gone through some changes over the years, with the stripes rearranging in the early 1800s, and the number of stars increasing from the original thirteen. The current design has been the same since 1960, when Hawaii became the 50th state. It was made by Betsy Ross and has since become a symbol of freedom and patriotism for the United States.
