Final answer:
The growth in population and economy during the Louisiana Territory period was significant and had a lasting impact on the United States. The westward expansion, driven by factors such as the Louisiana Purchase, industrialization, and the availability of cheap land, resulted in population growth and economic transformation. This growth, however, came at the expense of exploited labor and political tensions surrounding slavery.
Step-by-step explanation:
The growth in population and economy during the Louisiana Territory period was significant and had a lasting impact on the United States. With the Louisiana Purchase in 1803, the nation's size doubled, leading to a massive expansion westward. This expansion resulted in the displacement and decimation of Native American tribes and forced them onto reservations. It also triggered the growth of large plantations, the development of railroads, the discovery of mineral wealth, and the emergence of manufacturing and mechanization.
The population of the United States increased rapidly during this period due to the westward migration. The availability of cheap land in the west attracted people from eastern states. The industrial revolution also contributed to the growth of the economy. The market revolution occurred as the nation acquired more territory and resources, enabling the production of raw materials and the expansion of transportation and industry. However, this growth came at the expense of exploited labor, both slave and free.
The territorial expansion and economic growth also fueled political tensions, especially regarding the issue of slavery. The question of whether the new territories would be slave or free led to sectional conflicts and ultimately contributed to the outbreak of the Civil War.
