Pennsylvania, one of the original U.S. colonies, became an official state on December 12th, 1787. While the flag was not officially adopted until 1799, it originated at an earlier date. There is no clear and concrete evidence that Pennsylvania used one particular flag in its colonial days. However, it is known that Benjamin Franklin designed some military flags for the state in 1747. These designs were used throughout the American Revolutionary War by the state of Pennsylvania, and eventually influenced the design of the state's coat of arms and official state flag. In 1799, Pennsylvania Legislation officially adopted a state flag that had a dark blue field and was decorated with the state's coat of arms. On June 13th, 1907, the General Assembly of Pennsylvania announced that in order to be official the state flag must be the same blue as the blue found in the American Flag.
