The history of American expansion is a history full of strategy, luck, and courage. As a former British colony, the United States has always had a strong enterprising spirit since independence. With the support of its growing strength, this rising star used its own geographical advantages and did not hesitate to shift its appetite to the established empires, where the latter was huge and gradually aging. Open up the territory on the body.
Whether it was buying, intimidating, or occupying, Louisiana, Florida, Alaska, and Texas, which the United States once coveted, were eventually acquired one by one, reflecting her brilliance and success.
However, what you heard right is that, as a former power and the only contemporary superpower, the United States also
The reason for this history is actually well understood. On the North American continent, all parties
So, what are the main territories?
After the American Revolutionary War ended, Britain's prevention and containment of the United States became stronger, and American ambitions became more and more vigorous. In 1803, the United States purchased more than 2.14 million square kilometers of the Louisiana Territory from France and completed the territory area at a cost of 15 million US dollars.
Realizing that the British were still strong, the Americans carefully chose the Spanish North American colony as the next target for expanding their territory. The reason is simple, the declining Spanish empire's influence in North America
In 1810-1812, the U.S.’s impact on the West Florida region (now part of Louisiana and Alabama)
Coincidentally, in the 1810s, exiled Seminos and black slaves frequently traveled northward from Florida to Georgia to cross the border, which gave Americans good
At this time, the James Monroe government, which was worried about the alliance between the British and the West, was prepared to respond with a compromise for the time being, but the then Secretary of State and later the sixth president John Quincy Adams believed that the pressure of the Spanish was not enough. And was made by the independence movement in Latin America
In the end, the United States and the West finally signed the Adams-Eunice Treaty in 1819. The Americans obtained the Florida Peninsula and paid
However, it is interesting that the fledgling Americans did not choose to do too much in front of the old Spaniards. In the treaty concerning the direction of the border between the United States and the Spanish colonies
Looking at it now, the land abandoned by the Americans in this big deal roughly includes parts of today's eastern New Mexico, northwestern Texas, southeastern Colorado, southwest Kansas, and western Oklahoma.
Of course, the Americans later adopted the annexation of the Republic of Texas and the Mexican-American War
Although strictly speaking, the United States
And this famous parallel line of 49 degrees north latitude actually comes from the earlier 1818 Anglo-American "Agreement on Respect for Fisheries, Borders, and Compensation for Slaves", which is the more familiar boundary clause in the Anglo-American "1818 Treaty". The clause first stipulates that the vast area between British North America and the United States from Minnesota to the Rocky Mountains should be divided by 49 degrees north latitude, and secondly, it stipulates that the sparsely populated Oregon region is divided by
而这条著名的北纬49度平行线实际上来自早于1818年的英美《尊重渔业，边界和奴隶补偿协定》，这是英美《 1818条约》中较为熟悉的边界条款。 。该条款首先规定，从明尼苏达州到落基山脉的英属北美和美国之间的广大地区应北纬49度分开；其次，该州人口稀少的地区应按
In the "Treaty of 1818", in order to draw this parallel line, Britain and the United States made another territorial transaction. The United States acquired the most northwestern tip of the Mississippi River basin in the Louisiana Territory, which covers today's Canada. The Milky River, Poplar River, and Big Nixi Watersheds in Alberta and Saskatchewan
However, from a historical perspective, it should be said that the United States has lost
Having said that, why did a line of 49 degrees north latitude prevent Americans from going north in 1818, and why couldn't the United States collect the entire Oregon condominium in 1846?
The answer is also very simple,
Therefore, no matter how radical the American expansionists are, they cannot ignore them. At the same time, the Americans are engaged in the annexation of Texas and the US-Mexico War. Faced with the huge benefits that are about to arrive, the two-line combat is The Polk government seems undoubtedly
Therefore, the factor of national power made the United States strategically stop at the parallel line of 49 degrees north latitude, but tactically possessed the territory of Minnesota and North and South Dakota. Faced with such a historical arrangement, do Americans today have any What about an accident?
Even in the 21st century, Americans are still thinking about territorial transactions. The most recent one has to do with Puerto Rico, the US free state overseas. On August 19, 2018, Miles Taylor, the former chief of staff of the U.S. Department of Homeland Security, stated that Trump
即使在21世纪，美国人仍在考虑领土交易。最近的一个与美国自由国海外波多黎各有关。 2018年8月19日，美国国土安全部前参谋长迈尔斯·泰勒（Miles Taylor）表示，特朗普
Prior to this, overseas territories such as Guam had reported similar trading news more than once, but they have basically been proved to be false news. But this time seems to be different. Trump's businessman nature and political style make people think that this deal may not be just news.
Puerto Rico aspires to have the same status as Hawaii in the United States.
So why does Trump want to move such a thought?
To put it simply, on the one hand, he felt that he could avoid making the U.S. government fall into a heavier financial dilemma. For the U.S., Puerto Rico has a significantly higher status than unincorporated territories, but it is still relative to its native states.
Considering that Puerto Rico does not have an unparalleled strategic location like Hawaii, the Americans are also nearby.
On the other hand, the more important point is that the notion of selling Puerto Rico may be part of an American-style blind trading strategy. According to Miles Taylor’s further revelation, for Trump, trading Puerto Rico’s
Despite repeated unsuccessful attempts, the United States has retained its presence in Greenland through the defense agreement between NATO and the United States.
Of course, as it did with Spain at the time, if the United States really makes up its mind, it is likely to
In the end, the interesting outcome was that millions of Puerto Ricans who worked hard to be 100% American became Danes somehow, while more than 70,000 residents of Greenland, who were highly independent, became American citizens. The thirst of Greenland should not be limited to these 70,000 unhappy islanders!
