8.5.2

Know the changing boundaries of the United States and describe the relationships the country had with its neighbors (current Mexico and Canada) and Europe, including the influence of the Monroe Doctrine, and how those relationships influenced westward expansion and the Mexican-American War.
             Relationship between the nation's neighbors, now Mexico, Canada, and Europe, led to the expansionism of the US boundaries, and includes the influence of the Monroe Doctrine, and those relationships influenced westward expansion and the Mexican-American War. New principles were concluded in the Monroe Doctrine, passed by President Monroe as the following that colonization would not be allowed in the Western Hemisphere, a change of political system to differ from Europe's and America's, if any affairs are threat related, the US would not participate, and wars with Europe shall not disturb the colonies that are already withhold in the Western Hemisphere. The result of the Monroe Doctrine gave a weakened bond between foreign countries, especially Europe, though it had its good and bad. One of the successful point was power over the Western region. But the trade with Britain would never be the same, for as the merchant's door closed and some resources were lost.
             Struggling to tie peace together with Mexico, America just couldn't bear to let a nation, another from their own, keep California and New Mexico, as Manifest Destiny fell into the minds of the Americans, wanting the expansion of territory up to the Pacific. The most momentous conflict began on April 25, 1846, the Mexican-American War that lasted for two years until the Treaty of Guadeloupe Hidalgo [February 2, 1848] was signed, keeping harmony between its other nations how their relations could go wrong. The Treaty of Guadeloupe Hidalgo is still intact today, the law that let us have the Rio Grande [boundary of Texas], and also California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado and Wyoming. Because of the downfall in money, Mexico sold these land for a cost to cover debts, where then the US had also fell to the debt pit. Now the experiences are over, and the changing boundaries of the United States is what we have most of today. Even though the relationships weren't joyful, they change over time, but as land wise, we own it, and it is rightfully ours.
