Final answer:
The Era of Good Feelings was characterized by national unity and patriotic fervor post-War of 1812, marked by James Monroe’s presidency, economic and judicial nationalism, and the Monroe Doctrine. Despite the era’s name, underlying tensions foreshadowed a return to partisan politics.
Step-by-step explanation:
The Era of Good Feelings is a period in American history marked by high levels of patriotism and national unity following the War of 1812. During President James Monroe's administration, heightened nationalism was reflected in policies aiming to promote a stronger, more self-sufficient nation.
The Treaty of Ghent concluded the war and Monroe's goodwill tour helped heal regional divides, while his near-unanimous reelection in 1820 signaled widespread support. Congress established the Second Bank of the United States, passed a protective tariff, and the Supreme Court delivered rulings, such as Dartmouth College v. Woodward, that reinforced federal power and fostered economic development. Notably, the Monroe Doctrine established U.S. foreign policy principles in the Western Hemisphere. Nonetheless, issues like the Panic of 1819 hinted at underlying economic and political tensions that would eventually rekindle partisan politics.
