There are reasons to support the justification of Manifest Destiny. Manifest Destiny was a belief many Americans held that it natural for us to rule the land from the Atlantic Ocean to the Pacific Ocean. One reason for this belief was that we needed to take care of our people. The farmers in the West needed to use the Mississippi River and the port of New Orleans so they could get their crops to customers in the United States and around the world. When we weren’t allowed to freely use the Mississippi River and weren’t allowed to store products at New Orleans, it was natural for us to want to acquire the land to make this possible. When our initial offer for New Orleans and for West Florida was rejected, it made sense to accept the far better offer Napoleon made to us for all of the Louisiana Territory. Once we made the Louisiana Purchase, we doubled the size of the country.
After we made the Louisiana Purchase, it was natural for us to want to learn more about the land we just bought. Various explorers went into these lands and brought back valuable geographic and scientific information. This information encouraged people to consider relocating to the new lands. Once minerals were discovered, that movement was greatly accelerated.
Another reason that justified the idea of Manifest Destiny was the growth the occurred because of it. As Americans expanded westward, the areas to which they moved grew in various ways. As people moved westward, more farms were established. Since the people who moved to the West needed products, businesses began to move to the West. This occurred as we began to expand our transportation into the West. The National Road was expanded, and railroads expanded further west. This progress helped the West grow and develop. Before we moved westward, the regions that were west of the Mississippi River weren’t growing or developing very much. Because of Manifest Destiny and the movement of Americans into these regions, the western regions experienced significant growth and development.
The United States became interested in becoming a world power in the late 1800s. Without expansion from the Atlantic Ocean to the Pacific Ocean, the West wouldn’t have been developed. We needed to develop our country before becoming a world power. Once we expanded to and developed the West, we could then think of taking the concept of Manifest Destiny and expanding throughout the world. This occurred in the late 1800s and in the early 1900s. This worldwide expansion helped make the United States a world power.
There are several reasons why our policy of Manifest Destiny was justified.
