The Annin Connecticut State Flag, which is among one of the most ancient state flags, was originally used during the Revolutionary War when Connecticut troops used this seal on their flag. The flag, consisting of a blue field with the arms in the center, was officially adopted in 1895 after pressure from the Daughters of the American Revolution. On June 3, 1897, it was regulated that the arms should be in color in the center of a field of azure blue. The flag was originally supposed to be squarish, but further regulations in 1957 said the flag had to have proportions of 2: 3. These US state flags are a great way to show pride in your home state.
