The land acquisitions in the United States
The land acquisitions in the United States were precipitated by the success recorded in the preceding wars. Motivated by the successful acquisition of the Oregon country in 1846 following the Anglo-American Convention of 1818, the United States went on land acquisition spree in the decade that followed. Between 1818, The United States acquired the two prime lands to add to its territory. These include the Gadsden Purchase of 1853 and the Guano Islands Act of 1856 that given the United States the powers to control Baker Island, Howland Island and Navassa Island. These were successfully annexed in 1857 by the land provisions of the same year. The first acquisition of the Gadsden Purchase of 1853 was acquired for $10 million that borders along New Mexico and Arizona. The area around the Southern Arizona and Southern New Mexico was named after the United States Minister for Mexico during the period (James Gadsden) because of his active role in the negotiations that led to the purchase of the land.
I totally believe abide in the belief of the irrepressible conflict that the war was inevitable. The reasons behind this assertion are not particularly hard to discern. First, the shift away from subsistence farming by a majority of farmers in the North, the migration of thousands of both white and black slaves and the renewal of slavery as an economic activity. The above factors triggered sharp differences on economic and social interests that were deeply manifested in party politics. The divergent views in social, economic and political aspects that had their roots from the colonial times separated the two regions further and further apart as such, these disputes could not be settled on the table. This was because of lack of an arbitrating body to close in the divide between the two opposing sides. In addition to the above, the loose American constitution at the time could not guarantee equal representation of all divergent interests of the South and the North.
