List five significant transformations the u. s. underwent during the period from 1800 to 1845.

First, the Market Revolution—the shift from an agricultural economy to one based on wages and the exchange of goods and services—completely changed the northern and western economy between 1820 and 1860. After Eli Whitney invented the cotton gin and perfected manufacturing with interchangeable parts, the North experienced a manufacturing boom that continued well into the next century. Cyrus McCormick’s mechanical mower-reaper also revolutionized grain production in the West. Internal improvements such as the Erie Canal and the Cumberland Road, combined with new modes of transportation such as the steamboat and railroad, allowed goods and crops to flow easily and cheaply between the agricultural West and manufacturing North. The growth of manufacturing also spawned the wage labor system.

Second, American society urbanized drastically during this era. The United States had been a land comprised almost entirely of farmers, but around 1820, millions of people began to move to the cities. They, along with several million Irish and German immigrants, flooded northern cities to find jobs in the new industrial economy. The advent of the wage labor system played a large role in transforming the social fabric because it gave birth to America’s first middle class. Comprised mostly of white-collar workers and skilled laborers, this growing middle class became the driving force behind a variety of reform movements. Among these were movements to reduce consumption of alcohol, eliminate prostitution, improve prisons and insane asylums, improve education, and ban slavery. Religious revivalism, resulting from the Second Great Awakening, also had a large impact on American life in all parts of the country.

Third, the major political struggles during the antebellum period focused on states’ rights. Southern states were dominated by “states’ righters”—those who believed that the individual states should have the final say in matters of interpreting the Constitution. Inspired by the old Democratic-Republicans, John C. Calhoun argued in his “South Carolina Exposition and Protest” essay that the states had the right to nullify laws that they deemed unconstitutional because the states themselves had created the Constitution. Others, such as President Andrew Jackson and Chief Justice John Marshall, believed that the federal government had authority over the states. The debate came to a head in the Nullification Crisis of 1832–1833, which nearly touched off a civil war.

answer: the correct answer is c.

explanation:

after the civil war, and with the termination of slavery, the south was faced with a big problem; what was supposed to happen and how they were supposed to deal with the freedom and the rights that black people and freed slaves had gained as a result of the north defeating the south and forcing the end of slavery. first, most, if not all, of the workforce of the south came from slaves and they did not have an option to replace the loss of said workforce. second, particularly in the south, people were convinced that black people were lesser, less intelligent, less capable and less smart than whites. this posed a huge problem for them. also, southerners were faced with another issue; freed slaves now had a say in how their lives would be lived and the right to politically choose the way they would be governed. people in the south did not want to accept this, none of this and this opposition and the conflicts that arose from it, not to mention the afereffects of the war, forced the congress of the time to enact and enforce the reconstruction plans that had been proposed by president andrew johnson.
