In 1783, through Treaty of Paris (1783), Britain recognized the sovereignty of the United States，and offered to cede all the land between the east of the Mississippi River and the Atlantic coast. In 1803, the Louisiana Purchase almost doubled the nation’s area. In 1819 because of internal and external troubles, Spain entered into Adams–Onís Treaty of 1819 with the United States, which led Spain cede Florida and other Gulf Coast territory. Then, the United States successively obtained the Texas and Oregon areas from Mexico and Britain by means of countermeasures and threats. In 1848, the victory of America in the Mexican-American War resulted in the Mexican Cession of California through the 1848 Treaty of Guadalupe Hidalgo. Then in 1853, James Gadsden, U.S. ambassador to Mexico at that time, bought nearly 100 thousand square kilometers of land along the US-Mexico border for $10 million. In 1867, the United States purchased Alaska from the Russian Empire for 7.2 million dollars, which covers an area of 1.5 million square kilometers. In the late nineteenth Century, the United States also acquired some islands in the Pacific through
war, such as Hawaii. Although this is twenty-first Century, the ambitions of American expansion never cease.

1776年7月4日，北美洲的13个殖民地宣布脱离英国独立。1783，通过《巴黎条约》（1783），英国承认了美国的主权，并提出放弃在密西西比河以东和大西洋海岸之间的所有土地。1803，路易斯安那购地案使美国领土几乎翻了一番。1819，由于内部和外部的麻烦，西班牙与美国签订了亚当斯欧尼斯条约（1819），导致西班牙放弃佛罗里达州和其他海湾沿岸领土。随后，美国通过策反和威胁先后从墨西哥和英国先后获得了德克萨斯和俄勒冈地区。1848，美国在美墨战争中的胜利，促成了墨西哥通过1848瓜达卢佩-伊达尔戈条约的加利福尼亚割让。1853，美国驻墨西哥大使James Gadsden在美国墨西哥边境购买了近10万平方公里的土地，价值1000万美元。1867，美国从俄罗斯帝国用720万美元购买了阿拉斯加，占地面积150万平方公里。在十九世纪下旬，美国也通过战争获得了太平洋上的一些岛屿，比如夏威夷。尽管现在是二十一世纪，但是美国扩张的野心从未停止。 去哪儿旅行下载
