Answer:
Part A
Many American residents subscribe to the concept of manifest destiny, the theory that Americans are destined to spread throughout North America.
To succeed, there are three elements to take into consideration; American values and institutions, which form a distinct character of American society; the country's mission to redeem and remake the American West according to the ideals of the agrarian East; and an inescapable destiny to accomplish this fundamental duty. Native Americans were subjected to genocidal policies based on the concept of manifest destiny, which has been widely criticized.
As Thomas Jefferson notes in a letter to James Monroe, "Our quick multiplication will spread over the northern and southern continents, unless we learn to control it." It may be likened to a "inauguration of a new time scale" since the globe would see history from before and after the Declaration of Independence as distinct epochs. In some people's eyes, a spiritual duty to extend its political system and way of life across North America, underlies the establishment of a central governing authority in North America.
Part B
With the Treaty of Paris, the United States acquired independence, extending its boundaries seven times, with two major boundary modifications (with the UK and Spain), and many smaller conflicts. Most of the United States started off as territories that later evolved into states.
The main trend observed in this carving, alteration, and ultimate statehood is of geographical growth. Two out of the six states, Nevada and Missouri, increased their total area since statehood. In the five other states, Georgia, Massachusetts, North Carolina, Texas, and Virginia, each of the five former states lost territory to the new state.
Part C
A total of 828,000 square miles, equivalent to the entire land mass of Europe, was bought for 15 million dollars (2,140,000 km2; 530,000,000 acres). 2.6-3.4 billion: the total cost of all treaties and financial settlements related to the land following.
The purchase of Louisiana was a goal of the administration of President Thomas Jefferson. In 1800, France had recovered most of its former North American territories, which included New Orleans. Until 1762, Louisiana was part of the French Empire. The sale brought more states into the Union such as Arkansas, Missouri, Iowa, Oklahoma, Kansas, Nebraska, North Dakota, South Dakota, Montana, Wyoming, Minnesota, Texas, New Mexico, Louisiana, and New Orleans. The Louisiana Purchase granted the U.S. control of the Mississippi River. Louisiana had approximately 60,000 non-natives in 1733. approximately half of the people purchased were African slaves
