The First Pennsylvania Constitution was created August 1776.

The Coat of Arms on the Flag of Pennsylvania was created in 1778.

The Flag was created in 1799.

In 1906 the Blue back ground called "the color of old Glory" was set as a standard blue color. 

For the most part the flag has not changed in two hundred years.

The yellow fringe does not belong on the original flag and the bright colors were additions as well.
