The Volokh Conspiracy

Acquired Cities:

Many times over the last two centuries, the United States has acquired land. A lot of the land was sparsely inhabited, but some contained cities. Name the city that was the most populous at the time of its acquisition.

(If the city became part of a Territory when it was acquired, and then part of a State, I'm counting the population at the time it became part of a Territory. Let's include for purposes of the question the land the U.S. "acquired" at the time it was created. And let's exclude land — such as Germany or Japan after World War II — that the U.S. merely ruled as a self-consciously temporary occupation. People who like to bring legal disputes even into geography problems should note that I'm assuming, together with Lincoln, that the seceding South never actually became foreign land, and thus wasn't reacquired in 1865.)

Here I don't have the precise statistics, but I'm pretty sure I know the right answer. I thought that, rather than just giving it, I'd ask people to post their thoughts on the Comments; naturally, if you have authoritative sources handy — or, better yet, linkable — you should post those. Later on (probably tomorrow), I'll post the right answer, together with an admission if it turns out that I got the answer wrong myself -- though as it happens, I've already posted my guess.

But since I'm not one, I'll agree with the above: Manila.

Always go with the first guess; unless it's wrong. Then try the second.

New Orleans population at the time of the Louisiana Purchase was about 8000. San Francisco was about 30,000 in 1852, and was probably bigger than 8000 in 1848, which is when the US acquired it in the Treaty of Guadalupe Hidalgo (I don't think California was ever independent).

Manila could have been larger, I dunno.

However, I do think you've telegraphed the answer with this sentence: Let's include for purposes of the question the land the U.S. "acquired" at the time it was created.

Assuming the US was created in 1787, the answer would by New York City with a population of about 33k.

Oh, I read this wrong. I thought you'd said excluding that.

So basically, the question is: "Did the U.S. acquire any city larger than 33K in the 200 plus years since its founding?"

Elias:

It's ambiguous. The first letters of each sentence spell out something dangerously approaching "Manila Phil."

Ah, but not so fast! The last letters of each sentence spell out "dsnydn5res." This is an obvious anagram of "Dry 'n' sends 5." Now, it's pretty clear that "dry 'n' sends" must refer to the water-based commerce that's historically associated with New Orleans. Well, what about the "5"? I got it! That's a reference to the 5th Circuit, which is headquartered in that city.

Way to straddle the issue, Volokh!

Manila was my guess and based on the research I did on the net I think its right. New Orleans, San Fran, etc. were all smaller than Manila at the time they were acquired. I also don't think that Manila can be excluded as not being a "territory that we expected ultimately to be incorporated into the United States." I don't think history would necessarily support the view that when the U.S. acquired the Philippines we didn't intend to keep it. We did fight a war with them over it after all.

Although Manila may be the right answer, I'd be inclined to think of San Juan, Puerto Rico. At the time of the SAW, the population of PR was about 1 million people, and I would think a high proportion would have been in San Juan. Would think that Manila would have been a smaller city at that time.

New York is clearly wrong, because Philadelphia was a larger city at the time the U.S. became independent.

KW: Havana doesn't qualify under the ground rules set by Prof. Volokh, because we expected from the get-go that we would just hold Cuba for long enough to put it on its feet and give it independence (as in the cases of Germany and Japan). (The Philippines were quite another matter. We didn't reconcile ourselves to Philippine independence until the mid-30s.)

The U.S. did a census of the Philippines in 1903, at which time Manila had a population of 219,000 (http://www.library.uu.nl/wesp/populstat/Asia/philippt.htm). Presumably the population was not much lower in 1898-99. That beats New Orleans in 1803, Honolulu in 1898, San Francisco in 1848, and New York or Philadelphia in 1776 hands down.

Tex the Pontificator (mail) (www):
Jeffery McLaren suggests San Antonio's population was 63,000 upon Texas's joining the union. Before I checked it out, I wondered if San Antonio wasn't the answer, but the Handbook of Texas Online indicates San Antonio's population then was much lower. It shows it as only 3,488 in 1850, well after annexation. I'd be surprised if Texas had a population of 63,000 back then.
5.19.2005 7:37pm
A.S.:
According to this (http://dodgson.ucsd.edu/las/cuba/1898-1901.htm), Cuba had approx 1,600,000 in population in 1900 (418,000 voting age males constituting 26% of the total population). Also, it seems a quarter or so of the population lived in Havana (or at least Havana province): "Thirty-one delegates were elected, apportioned among the provinces according to population, with Havana getting eight, Santa Clara and Oriente seven apiece, Matanzas four, Pinar del Río three, and Camaghey two."

FWIW, at the time Calif. joined the union, I'd guess Sacto was larger than S.F., but only by a little bit, maybe a couple thousand, but I could be wrong, as to the question, I do think Manila, is probably right.

A.S.: IIRC, Cuba was occupied temporarily with intent to return sovereignty once order was restored.

New Orleans, but not when it was purchased from the French. Rather, when it reconquered during the Civil War. Population was 168,675 in 1860, 191,418 in 1870. (source).

Well, the occupation of the Philippines was concededly "temporary," while "self-consciously" is a matter of interpretation -- ask, say, William Jennings Bryant.

But suppose we restrict ourselves to territories that the U.S. still controls, for the sake of argument. As far as I can tell, of those two it's either Honolulu or San Juan, and I'm having trouble finding reliable historical population figures for the latter.

Hmmm. Land at acquired at the time it was created... Not much land created these days—certainly not much that's got a population. Still, Battery Park City in Manhattan was created in 1976 as landfill made from the dirt excavated during the World Trade Center construction. It is home to about 25,000 New Yorkers, and at the time it was created, its residential space was fully subscribed—so I suppose you could say it had a population. At about 70,000 people per square km, it was surely the most densely populated territory ever acquired by the U.S.

Therefore the answer is: Lincoln, in the Nebraska Compromise Purchase of 1849.

I'll guess Santa Fe. It was always a significant administrative center for Spain/Mexico, and would have been a decent size when it was acquired at the end of the Mexican war.

Anthony Argyriou (mail) (www):
San Juan, PR, is not the answer. Its population in 1899 was 32,048, less than the 39,306 in 1900 which Adam found for Honolulu.

I'm pretty much convinced it's Manila, as its population in 1887 was 176,777 and was 219,928 in 1903, so even if the population increase between 1887 and 1903 was mostly after 1898, it still beats anything else offered.

Even if we count the restoration of US soveriegnity over the Confederacy as "acquisition", it's close between New Orleans and Manila - New Orleans' population in 1870 was 191,418, while Manila's was 219,928 in 1903, also five years after acquisition.

How does Manila not constitute a "merely ruled as a self-consciously temporary occupation" situation? I'm given to understand that, unlike Hawaii, Congress never voted to annex the Philippines. That would seem to disqualify it.

So I'm going to bet on a long shot and say the ten mile strip of territory surrounding the Panama Canal :-)

jallgor (mail):
I don't think that whether Congress' ever voted to annex the Philippines is really relevant to whether the acquisition was "self-consciously temporary." For example, the U.S. acquired Guam and Puerto Rico at the same time as the Philippines (and under similar terms) and we still claim them as territories today. I think history shows that at the time we signed the Treaty of Paris we intended to keep the Philippines the same way we did Puerto Rico and Guam. Of course, it turned out differently with the Philippines but that's irrelevant.
Treaty of Paris (1989)
"Article II. Spain cedes to the United States the island of Porto Rico and other islands now under Spanish sovereignty in the West Indies, and the island of Guam in the Marianas or Ladrones.

Article III. Spain cedes to the United States the archipelago known as the Philippine Islands . . . ."

Instead of answering, I'll debate the question. Professor Volokh commands, "Name the city that was the most populous at the time of its acquisition." The superlative "most" indicates that since acquisition the population has declined.

Hmm, on reading Eugene's initial post, I saw his "encrypted" Manila, thought maybe New Orleans, but discounted it as much too small in 1800 for the Louisiana Purchase. Given the inclusion of the original colonies, I might guess Boston, though New York does sound plausible though both sound too easy.

After cheating by checking internet data on census records, I vote: Manila, I found data showing a pop. of 154,000 in 1887. (here's the reference) What bothers me is Eugene says he was incorrect. My Boston thought was way off and Manila beats the entire state of New York at the Revolution (it also beats the State of California at the gold rush).

Warmongering Lunatic:
"Self-consciously temporary" is, unfortunately, rather vague.

William Jennings Bryan endorsed the peace treaty that included the annexation just to end the war with Spain, with the understanding that the U.S. could then grant the Phillipines independence anyway. And McKinley's First Philippine (Schurman) Commission recommended merely an indefinite occupation, with Phillipine independence to be granted in the future. So the treaty that included the annexation only passed with the support of those opposed to annexing the Phillipines, and many of the supporters of annexation supported it as merely a temporary measure.

On the other hand, there were definitely permanent-annexationists who voted for the annexation as well, and there was nothing adopted at the time to guarantee eventual independence.
