he words 'people of the United States' and 'citizens' are synonymous terms, and mean the same thing. They both describe the political body who, according to our republican institutions, form the sovereignty, and who hold the power and conduct the Government through their representatives. They are what we familiarly call the 'sovereign people,' and every citizen is one of this people, and a constituent member of this sovereignty. The question before us is, whether the class of persons described in the plea in abatement compose a portion of this people, and are constituent members of this sovereignty? We think they are not, and that they are not included, and were not intended to be included, under the word 'citizens' in the Constitution, and can therefore claim none of the rights and privileges which that instrument provides for and secures to citizens of the United States. On the contrary, they were at that time considered as a subordinate and inferior class of beings, who had been subjugated by the dominant race, and, whether emancipated or not, yet remained subject to their authority, and had no rights or privileges but such as those who held the power and the Government might choose to grant them.

We think they are before us. The plea in abatement and the judgment of the court upon it, are a part of the judicial proceedings in the Circuit Court, and are there recorded as such; and a writ of error always brings up to the superior court the whole record of the proceedings in the court below. And in the case of the United States v. Smith, (11 Wheat., 172,) this court said, that the case being brought up by writ of error, the whole record was under the consideration of this court. And this being the case in the present instance, the plea in abatement is necessarily under consideration; and it becomes, therefore, our duty to decide whether the facts stated in the plea are or are not sufficient to show that the plaintiff is not entitled to sue as a citizen in a court of the United States.

Now, it is not necessary to inquire whether in courts of that description a party who pleads over in bar, when a plea to the jurisdiction has been ruled against him, does or does not waive his plea; nor whether upon a judgment in his favor on the pleas in bar, and a writ of error brought by the plaintiff, the question upon the plea in abatement would be open for revision in the appellate court. Cases that may have been decided in such courts, or rules that may have been laid down by common-law pleaders, can have no influence in the decision in this court. Because, under the Constitution and laws of the United States, the rules which govern the pleadings in its courts, in questions of jurisdiction, stand on different principles and are regulated by different laws.

n May, 1854, the cause went before a jury, who found the following verdict, viz: 'As to the first issue joined in this case, we of the jury find the defendant not guilty; and as to the issue secondly above joined, we of the jury find that before and at the time when, &c., in the first count mentioned, the said Dred Scott was a negro slave, the lawful property of the defendant; and as to the issue thirdly above joined, we, the jury, find that before and at the time when, &c., in the second and third counts mentioned, the said Harriet, wife of said Dred Scott, and Eliza and Lizzie, the daughters of the said Dred Scott, were negro slaves, the lawful property of the defendant.'

At the times mentioned in the plaintiff's declaration, the defendant, claiming to be owner as aforesaid, laid his hands upon said plaintiff, Harriet, Eliza, and Lizzie, and imprisoned them, doing in this respect, however, no more than what he might lawfully do if they were of right his slaves at such times.

In the year 1838, said Dr. Emerson removed the plaintiff and said Harriet and their said daughter Eliza, from said Fort Snelling to the State of Missouri, where they have ever since resided.

In the year 1835, Harriet, who is named in the second count of the plaintiff's declaration, was the negro slave of Major Taliaferro, who belonged to the army of the United States. In that year, 1835, said Major Taliaferro took said Harriet to said Fort Snelling, a military post, situated as hereinbefore stated, and kept her there as a slave until the year 1836, and then sold and delivered her as a slave at said Fort Snelling unto the said Dr. Emerson hereinbefore named. Said Dr. Emerson held said Harriet in slavery at said Fort Snelling until the year 183

In the year 1834, the plaintiff was a negro slave belonging to Dr. Emerson, who was a surgeon in the army of the United States. In that year, 1834, said Dr. Emerson took the plaintiff from the State of Missouri to the military post at Rock Island, in the State of Illinois, and held him there as a slave until the month of April or May, 1836. At the time last mentioned, said Dr. Emerson removed the plaintiff from said military post at Rock Island to the military post at Fort Snelling, situate on the west bank of the Mississippi river, in the Territory known as Upper Louisiana, acquired by the United States of France, and situate north of the latitude of thirty-six degrees thirty minutes north, and north of the State of Missouri. Said Dr. Emerson held the plaintiff in slavery at said Fort Snelling, from said last-mentioned date until the year 1838.
