In the 1840s the United States increased its territory to stretch from the Atlantic to the Pacific Ocean. This land was acquired through treaty, war, and negotiation. The opportunities of this large area of land offered in terms of resources and trade were great. The positive of M.D. do not outweigh the negative consequences. Manifest Destiny is a historic duty, in the 1800’s the Americans believed that the manifest destiny of the United States was to expand to the Pacific Ocean. The United States started as costal colonies but eventually the fulfilled their manifest destiny and expanded buy conquering and purchasing land. The Americans gained more land by buying it from France in the Louisiana Purchase and they also acquired land by cession as they did in the Mexican Cession. Other ways of expanded their land was to take it by force; many settlers killed the Indians and stole their land from them. The Americans in the 1800’s believed that it was the historic duty of their nation to expand to the Pacific Ocean. They believed that the land was rightfully theirs. They ignored the fact that the land was already occupied and began to move west. They did not recognize the Indians as people; they saw them as potential slaves, so they simply killed them and took their land. Much of the land was bought from France in the Louisiana Purchase, but other lands such as Texas, California and Oregon was not theirs. Using both military strength and negotiations, the US was determined to fulfill their historic duty. The main difference between the border issues of Oregon and Texas is the way these issues were settled. The Texas issue resulted in a war with Mexico, which gained land and lost soldiers. However, this did allow the US to gain more land than just Texas. The Oregon issue, on the other hand, was more peaceful. The US negotiated and made a treaty with Britain instead of going to war with them. However, both these issues were different ways the US gained land and expanded their nation.
