Subjects existed in tandem with citizens in America in 1763, 1776, 183, 1789, 1790, 1866, 1898, 1920, and 2016. The fact that Thomas Jefferson and the other Founders drastically changed the proportions of those subjects versus citizens does not change the fact citizenship at the national level originated in the past and still originates today at the municipal level under a variety of word forms other than citizen. Swiss citizenship then and today existed/exists at three levels beginning with the municipal level, extends to the cantonal level, and extends again to the national level; yet still does not include those inhabitants who remain as subjects of Switzerland without Swiss citizenship. So, the word citizen still does not denote all of the inhabitants, nationals, or subjects of the United States or Switzerland.
But in English law and practice, only existed at the municipal level. The concept of a citizen "National" did not exist in 1776 England.
