Dominant Themes of American History

I think exploration and colonization are the most dominant themes in American history between 1607 and 1861. Throughout this semester, much of the topics seem to have been related to exploration or colonization. It started with Europeans exploring west.   John Smith and others explored the east coast when explorers first reached America. They created the Jamestown colony in 1607. More and more colonies were settled after this. The amount of colonies grew bigger and bigger. Soon, they began to grow less dependent on Great Britain. The colonies revolted and became independent from Great Britain. While the themes of exploration and colonization became less relevant as history continued, it never completely disappeared.even after the United States developed into a country, People started to expand west. Exploration was still required to explore the unfamiliar land. President Thomas jefferson gave the job of exploring the land recently bought from France in the Louisiana Purchase to Meriwether Lewis and William Clark. Their exploration lasted two years. After their exploration the U.S. Population slowly expanded west. They colonized the new western lands. After around 1850s, exploration seems to end (not entirely). Colonization doesn't entirely end though. New towns were being built regularly. Although it is not quite colonization, it is the same idea of making a new community. To me, these themes are the most dominant through this time in American history because they never cease to exist. They might not be a major theme at some points, but they never completely go away.
