Citizenship/Citizen

A citizen can be of two types: Either they owe allegiance to a government or they are a member of a state. These distinctions are made in the Merriam Webster dictionary as well as in Black’s Law Dictionary. Within our own system of law, you can be a citizen of the Federal Government, or a “citizen of a state”. You can also be both. With reference to jurisdiction and power of the federal courts however a citizen of the District of Columbia is considered not a “citizen of a state”.

These definitions also imply two very important concepts: “Allegiance” and “State”.

Citizen Definition, In American Law
One who, under the constitution and laws of the United States, or of a particular state, is a member of the political community, owing allegiance and being entitled to the enjoyment of full civil rights. Amy v. Smith, 1 Litt. (Ky.) 331; Minor v. Happersett, 21 Wall. 162, 22 L.Ed. 627.

But a state and the federal government each has citizens of its own, and the same person may be at the same time a citizen of the United States and a citizen of a state. The government of the United States can neither grant nor secure to its citizens rights or privileges which are not expressly or by implication placed under its jurisdiction. All that cannot be so granted or secured are left to the exclusive protection of the states. U. S. v. Cruikshank, 92 U.S. 542, 23 L.Ed. 588.

With reference to the jurisdiction and power of federal courts and removal of actions a citizen of the District of Columbia is not a "citizen of a state", Neild v. District of Columbia, 110 F.2d 246, 249, 71 App.D.C. 306; Glaeser v. Acacia Mut. Life Ass'n, D.C.Cal., 55 F.Supp. 925, 926;
