Then they understand THIS: According to a law that Parliament enacted in 1604 and which was still in effect when the U.S. Constitution was written, the English-born children of alien parents were "denizens," NOT natural born subjects:
"To place the Children, born within this Realm, of foreign Parents, in Degree for the first Birth or Descent only, as Aliens made Denizens, and not otherwise.

“II. The fundamental principle of the common law with regard to English nationality was birth within the allegiance, also called “ligealty,” “obedience,” “faith,” or “power” of the King. The principle embraced all persons born within the King’s allegiance and subject to his protection. Such allegiance and protection were mutual — as expressed in the maxim protectio trahit subjectionem, et subjectio protectionem — and were not restricted to natural-born subjects and naturalized subjects, or to those who had taken an oath of allegiance, but were predicable of aliens in amity so long as they were within the kingdom. Children, born in England, of such aliens were therefore natural-born subjects. But the children, born within the realm, of foreign ambassadors, or the children of alien enemies, born during and within their hostile occupation of part of the King’s dominions, were not natural-born subjects because not born within the allegiance, the obedience, or the power, or, as would be said at this day, within the jurisdiction, of the King.
This fundamental principle, with these qualifications or [p656] explanations of it, was clearly, though quaintly, stated in the leading case, known as Calvin’s Case, or the Case of the Postnati, decided in 1608, after a hearing in the Exchequer Chamber before the Lord Chancellor and all the Judges of England, and reported by Lord Coke and by Lord Ellesmere. Calvin’s Case, 7 Rep. 1, 4b-6a, 18a, 18b; Ellesmere on Postnati, 62-64; S.C., 2 Howell’s State Trials, 559, 607, 613-617, 639, 640, 659, 679.
The English authorities ever since are to the like effect. Co.Lit. 8a, 128b, Lord Hale, in Hargrave’s Law Tracts, 210, an in 1 Hale P.C. 61, 62; 1 Bl.Com. 366, 369, 370, 374; 4 Bl.Com. 74, 92; Lord Kenyon, in Doe v. Jones, 4 T.R. 300, 308; Cockburn on Nationality, 7; Dicey Conflict of Laws, p. 173-177, 741.
In Udny v. Udny, (1869) L.R. 1 H.L. Sc. 441, the point decided was one of inheritance, depending upon the question whether the domicil of the father was in England or in Scotland, he being in either alternative a British subject. Lord Chancellor Hatherley said: “The question of naturalization and of allegiance is distinct from that of domicil.” P. 452. Lord Westbury, in the passage relied on by the counsel for the United States, began by saying:
The law of England, and of almost all civilized countries, ascribes to each individual at his birth two distinct legal states or conditions: one, by virtue of which he becomes the subject of some particular country, binding him by the tie of natural allegiance, and which may be called his political status; another by virtue of which he has ascribed to him the character of a citizen of some particular country, and as such is possessed of certain municipal rights, and subject to certain obligations, which latter character is the civil status or condition of the individual, and may be quite different from his political status.
And then, while maintaining that the civil status is universally governed by the single principle of domicil, domicilium, the criterion established by international law for the purpose of determining civil status, and the basis on which
the personal rights of the party, that is to say, the law which determines his majority or minority, his marriage, succession, testacy or intestacy, [p657] must depend,
he yet distinctly recognized that a man’s political status, his country, patria, and his “nationality, that is, natural allegiance,” “may depend on different laws in different countries.” Pp. 457, 460. He evidently used the word “citizen” not as equivalent to “subject,” but rather to “inhabitant,” and had no thought of impeaching the established rule that all persons born under British dominion are natural-born subjects.
Lord Chief Justice Cockburn, in the same year, reviewing the whole matter, said:
By the common law of England, every person born within the dominions of the Crown, no matter whether of English or of foreign parents, and, in the latter case, whether the parents were settled or merely temporarily sojourning, in the country, was an English subject, save only the children of foreign ambassadors (who were excepted because their fathers carried their own nationality with them), or a child born to a foreigner during the hostile occupation of any part of the territories of England. No effect appears to have been given to descent as a source of nationality.
Cockburn on Nationality, 7.
Mr. Dicey, in his careful and thoughtful Digest of the Law of England with reference to the Conflict of Laws, published in 1896, states the following propositions, his principal rules being printed below in italics:
“British subject” means any person who owes permanent allegiance to the Crown. “Permanent” allegiance is used to distinguish the allegiance of a British subject from the allegiance of an alien who, because he is within the British dominions, owes “temporary” allegiance to the Crown. “Natural-born British subject” means a British subject who has become a British subject at the moment of his birth.” “Subject to the exceptions hereinafter mentioned, any person who (whatever the nationality of his parents) is born within the British dominions is a natural-born British subject. This rule contains the leading principle of English law on the subject of British nationality.
The exceptions afterwards mentioned by Mr. Dicey are only these two:
1. Any person who (his father being an alien enemy) is born in a part of the British dominions, which at the time of such [p658] person’s birth is in hostile occupation, is an alien.
2. Any person whose father (being an alien) is at the time of such person’s birth an ambassador or other diplomatic agent accredited to the Crown by the Sovereign of a foreign State is (though born within the British dominions) an alien.
And he adds:
The exceptional and unimportant instances in which birth within the British dominions does not of itself confer British nationality are due to the fact that, though at common law nationality or allegiance in substance depended on the place of a person’s birth, it in theory, at least, depended not upon the locality of a man’s birth, but upon his being born within the jurisdiction and allegiance of the King of England, and it might occasionally happen that a person was born within the dominions without being born within the allegiance, or, in other words, under the protection and control of, the Crown.
Dicey Conflict of Laws, pp. 173-177, 741.
It thus clearly appears that, by the law of England for the last three centuries, beginning before the settlement of this country and continuing to the present day, aliens, while residing in the dominions possessed by the Crown of England, were within the allegiance, the obedience, the faith or loyalty, the protection, the power, the jurisdiction of the English Sovereign, and therefore every child born in England of alien parents was a natural-born subject unless the child of an ambassador or other diplomatic agent of a foreign State or of an alien enemy in hostile occupation of the place where the child was born.”
