Gemini, what did the Slaughterhouse Cases say about the 14th amendment’s reference to “subject to the jurisdiction?”

The *Slaughterhouse Cases (1873)* famously narrowed the interpretation of the 14th Amendment, particularly its Privileges or Immunities Clause. While the case primarily focused on that clause, the Court also touched upon the "subject to the jurisdiction" language in the citizenship clause.

The 14th Amendment states: "All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside."

In the Slaughterhouse Cases, Justice Samuel Miller, writing for the majority, briefly clarified the meaning of "subject to the jurisdiction thereof." He stated that this phrase was intended to *exclude certain categories of individuals from automatic birthright citizenship*, even if they were born on U.S. soil. Specifically, he mentioned:

* *Children of foreign ministers or consuls:* These individuals are considered to be under the jurisdiction of their parents' sovereign nation, not the United States. * *Children of citizens or subjects of foreign states born within the United States:* This was a general exclusion for those whose allegiance was considered to be to another country, such as children of enemy aliens during wartime.

The primary purpose of this clause, in the context of the post-Civil War era, was to firmly establish the citizenship of formerly enslaved people, overturning the Dred Scott decision. However, the "subject to the jurisdiction" language ensured that certain exceptions to territorial birthright citizenship were maintained, consistent with international law and diplomatic practice.

It's important to note that while the Slaughterhouse Cases introduced this interpretation, the scope of "subject to the jurisdiction" for birthright citizenship was later more definitively addressed and affirmed in United States v. Wong Kim Ark (1898), which held that a child born in the United States to Chinese immigrants who were not citizens was indeed a U.S. citizen because he was "subject to the jurisdiction" of the United States.
