Before Alaska was the most northern state in the Union, Minnesota was King of the North. Before Minnesota, Michigan was King. Before Michigan, Maine was King. Before Maine, Massachusetts was King. Before Massachusetts, Pennsylvania was King. And as always Delaware was the original King of the North.
For a nearly two months from December 12, 1787 until February 6, 1788, and for the first Christmas and New Year's of the American Government - Pennsylvania was America's North Star.
For about 32 years from February 6, 1788 until March 15, 1820 Massachusetts was King of the North. She was unseated by her recently separated Siamese Twin - Maine.
Maine reigned as Lord of the North for 17 years from March 15, 1820 until little brother Michigan cut ahead on January 26, 1837.
Alaska has been the undisputed Cold King of the North for more than 52 years. Since Alaska is still reining North King, the flag goes unmarked and looks like this - here. For Australia the state of Queensland has the rights to fly this flag.
