After the War of 1812, the period that followed was seen as an "era of good feelings", mainly due to the emergence of a national party - the Republicans - and of the growth of nationalism and a feeling of national pride and unity. However, this title was incorrect for this time period, as sectionalism – the idea of ​​caring more about the interests of a particular group or nation than the interests of a larger group or country – began to grow and overtake nationalists, those who were loyal, proud and believed in the importance of their country. Sectionalism brought with it tensions and conflicts between the North and the South, especially over tariffs, the National Bank, and slavery, which suggested that the era was not entirely full of “good feelings.” After the War of 1812, the United States saw a nationalist spark begin to ignite. The emergence of nationalism was largely due to the Hartford Convention and the Federalists' call for secession from the Union. With the end of the war, the Federalist Party declined and the Republican Party emerged without any opposition.

In addition to fear that the United States does not seem subordinate ... middle of paper ... secretary of state. Southern states, which were Jackson supporters, were subsequently outraged and furious. They claimed it was unfair and classified it as “corrupt”. This drove a larger wedge between the Southern states and the Northern states, which had favored Adams. This political event embodied sectionalism and discredited the idea that this time was an “era of good feelings.” Although nationalism emerged after the War of 1812, it was quickly crushed and overshadowed by growing sectionalism and tension in the United States. Tariffs, the National Bank, and slavery played a role in further dividing the nation and ensuring the prevalence of sectionalism. Although the period was traditionally labeled the "era of good feelings", this was not the case at all, thanks to the emergence of sectionalism and the division between North and South..
