The age of empire

The U.S. became an empire after the Civil War, driven by industrial growth and a desire for global respect. Historian Frederick Jackson Turner's idea of an "expanding frontier" and Alfred Thayer Mahan's strategy for naval dominance influenced this shift. The U.S. acquired territories in the Pacific and Caribbean, marking its entry into world politics.

    Did this American imperialistic movement into the Pacific act as a cause for the significant increase in Japanese imperialism in southeast and east Asia in the 1920s?

      I think it's safe to say it was certainly ONE cause of Japan's interest in imperialism. Japan had similar motivations for empire as many European nations and the United States in this time period: a search for natural resources combined with heightened nationalism. Japan was particularly keen to get a reliable source of oil. The US expansion into the Pacific certainly made Japan wary of losing influence and territory in Southeast Asia and the Pacific islands.

      At in the video, Kim is talking about how after the Civil War, the American navy was small and had old, out-dated ships. In the 1890's they started building up a modern navy and making newer and better types of boats. For instance, the first American battleship was launched in 1892.

    Why did people want to go to Australia? Were there natural resources that they could use there or was it just to get more land?

      The British prisons were overcrowded, so they sent their prisoners to Australia, starting in 1788. Life was very hard at first. Their earliest export was whale oil. Eventually, they set up sheep farms, and by the early 1830's wool was a major export. In 1851 they discovered gold in Australia. Now, Australia's natural resources like minerals and oil are their largest export, but it took many years to get to that stage.

      Manifest Destiny is essentially over; since it's the idea that the United States is destined to get from Atlantic to Pacific. Since we've done that, and population is spread all over, we've achieved that mission. There is no more manifest destiny to accomplish.

    How and why does the United States have Territory outside of the Lower 48 States?

      United States Territory both inside and outside the lower 48 states was gained in different ways. Much of it came by purchase from France when the government of that nation was weak and broke. Texas came by welcoming in a neighboring independent republic. A lot of Mexico was taken in conquest. More of Mexico was acquired by purchase. Alaska was acquired by purchase from the Russian Empire. Hawaii was acquired when a group of Americans conspired and overthrew the local government. Puerto Rico and Guam were acquired as prizes of War. The US Virgin Islands were purchased from Denmark. American Samoa was taken as American in a deal between the USA and Imperial Germany. That's the "how". As for the "why", you'd have to ask the people at the times of the wars, purchases and annexations.

    It shows on the map of 1914 that Russia has a lot of land but much of it is unusable because of mountains or nutrient dry land, so my question is, why didn't they ever acquire colonies or territories? I mean, they were a world power. Another question that comes to mind is did Alfred Mahan actually say that a canal needed to be built and is his book what inspired the contractors to build the Panama Canal?

      Yes, Eugene V. Debs ran for president several times and won six percent of the vote in the 1912 presidential election on a Socialist Party ticket. There were also anarchists within the labor movement, though these aren't really the same as Communists. The Democratic party was sort of forced to co-op some of the spirit of angered progressives in order to keep socialists and communists out of power (think the New Deal). But the two largest nations which experienced Communist revolutions, China and Russia, had entirely different living conditions, and they both jumped basically from a feudal/semi-feudal state in the case of the Qing Dynasty in China and the tyrannical rule of the Tsar in Russia, into modernization under a Communist party. These nations had a large population of peasants with no hope of owning land or integrating into an urban lifestyle due to a lack of industrialization. That's probably a big part of the reason why a Communist party was not able to seize power in the United States, which was already modernizing and had very strong growing labor unions at the time (unlike today).

Video transcript

- [Voiceover] So I have a map here of United States possessions in the Pacific and in the Caribbean today, and they're kind of all over the place. And some of them are pretty tiny. There's Guam, which is just barely a little speck on the map, and American Samoa and more well known would be the Hawaiian Islands, right? One of the fifty states of the United States. Have you ever wondered why the United States has islands in the middle of the Pacific? This is thousands of miles from the mainland of the United States. So what's the deal? Did the United States just want access to somewhere to get a tan and maybe buy some pineapple? In this video I want to talk about the very unique, historical circumstances under which the United States acquired a bunch of territory outside of the borders of the lower 48 states. Or how, in other words, the United States became an empire. And empire, or imperialism, is the practice of having political or economic control over a territory that is outside the boundaries of your nation. So when did this happen and why did this happen? Let me give you a little background on the run up to the United States becoming an empire. So the Civil War ends in 1865, and while that is a conflict just within the United States, right, the definition of civil war, the Civil War has kind of an interesting effect on the United States' economy because for the the course of the Civil War the North really ramped up their industrial production to win the war. So they build railroad tracks and they have factories that help them build the armaments that are gonna help them with victory in the war. Well, after the war, all these factories, all these railroads still exist, and they're turned to different purposes. So over the course of the late 19th century from the end of the Civil War, really up until even 1900 and beyond, the United States becomes the leading industrial power in the world. So they make more stuff than anybody else, and this is one of the reasons why so many immigrants are flocking to the United States in this time period, because there are jobs in factories. But even though the U.S. was acknowledged as this great industrial power, it was not really acknowledged as a world military power. The number one power in the world at this time is England. This is the end of the Victorian Era. None of the nations of Europe think of the United States as an important power in the world. If you were a diplomat from France and you got a diplomatic posting to Washington D.C., that would be like getting a diplomatic posting on the moon. There is nothing going on there. Nobody's interested. You'd much rather be in Vienna or London. But another reason why the nations of Europe are such important world powers is because of their own investment in imperialism. So let me show you a map of the world in 1914, which is kind of after this age of imperialism, but it gives you an idea of how much territory Europe had gobbled up in this time period. So this is the rest of the world in this time period, and we're talking about kind of the period from about 1880 to 1900, and in this time period the powers of Europe really competed with each other to take over territories in the rest of the world. And these would have been developing nations, nations that did not have the firepower to compete with Europe, and they were generally nations with a lot of natural resources. So in the mid-19th century, there'd been explorers going throughout Africa. This is the period of Dr. Livingstone, I presume, and Dr. Livingstone reports back to England that there is a lot of stuff in Africa. We're talkin' about diamonds and gold and rubber, and elsewhere in the world, in India there's tea. And so in the 1880s, 1890s, Europe scrambles for territorial control of Africa and you see England here in South Africa, and France up here in northwest Africa, and then of course you've got England in India and Australia and they're even fighting for influence in China. And they had two main reasons for wanting these colonies abroad. One is, as we said, their natural resources, so they can take all the raw materials, the unfinished goods, to run the empire and then they can take that back up to Europe and process it. So it's a cheap source of stuff for their industrial production. The other thing they want is markets, so all of these territories, all of these colonies, have people in them who can buy the products from the European nations, and as their factories produce more and more stuff, they needed more and more people to buy those things or they're going to stagnate economically. So this is where the United States comes in. So in the late 19th century the U.S. has become this leading industrial power. They feel like they're not getting any respect from Europe for being pretty big dogs, but they also start looking at this scramble for Africa, this scramble for colonies in the world, and they think maybe the United States should get in on this game, and they have a couple of reasons for doing this. One of the reasons for doing this is the idea of expanding the frontier. So in the late 19th century, there was a pretty famous historian by the name of Frederick Jackson Turner. And what Turner has to say really troubles a lot of people. He says manifest destiny is done. So manifest destiny you'll recall, is this idea that God wanted the United States to occupy the North American continent from Atlantic to Pacific. As of 1890, the census showed that there was pretty much even population distribution all the way to the Pacific Ocean, so this process of conquering the frontier that many white Americans thought was really crucial to the American spirit, was over. So what is the United States going to do? Culturally they pride themselves on being a pioneering people. But along with that goes the same sort of quest for new markets that Europe is going through in the same time period. So if the United States is the world's leading industrial power, and they did that by conquering the frontier, building railroads, finding new people to sell the products of their factory to, what's going to happen if they have nowhere else to expand? Relentless expansion is kind of the backbone of American capitalism. And so people started to worry that if expansion is done, then the American industrial project is going to falter with no new markets to conquer. All right, so those are the economic and cultural explanations for why the United States became interested in being an imperial power at the end of the 19th century. There are also some military explanations, so let me take you back to a map of the Pacific. So in 1890, this man named Alfred Thayer Mahan published a book called The Influence of Sea Power Upon History. And Mahan's thesis was that all the great nations of history since time immemorial had gotten their greatness through a domination of the seas. So he says that if the United States really wants to be a world power going forward, they're going to have to make some serious investments in their navy. He says first they're going to have to build a really powerful naval fleet, which has never really been the bread and butter of America's military. Up until this point, the United States' navy was like five leaky boats. So he says they have to build a powerful navy and that you should consider putting a canal somewhere across Central America so that if a ship is in the Atlantic it doesn't have to go all the way around South America to get to the Pacific. It can just cut this corner here. And the last thing that Mahan says is that the U.S. is going to need friendly ports all over the world so that this navy can dock places, refuel, take on new supplies, because if your ports are only on the edges of the United States, it could take you days and days and days to make it all the way over to Asia. So Mahan says we need good harbors along the way. And you know what's a really great harbor? Pearl Harbor in Hawaii. It's one of the best harbors in the world. And basically in the future the U.S. government is going to to do exactly what Mahan says. In between 1890 and 1914, the United States increases their investment in the navy by a power of seven. It's $22 million dollars only in 1890. By 1914 they're putting $140 million dollars a year into their navy. And they will move forward with this plan to build a canal somewhere in Central America. Hint, hint, it might be in Panama. And they will annex ports all over the Pacific, and also in the Caribbean, to take care of their new powerful navy. So in the late 19th century, the U.S. is really poised to enter into world politics as a major world power. In the next video I'll talk about the Spanish American War of 1898 and how that led the United States to become an empire.
