Step-by-step explanation:
The time period from 1815 to 1828 is known to US historians as the Era of Good Feelings.
After the War of 1812, patriotic feelings ran high in the United States, leading to the emergence of this era. During this time, American leaders worked towards promoting a stronger and self-sufficient United States. Congress passed certain measures such as chartering the Second Bank of the United States, approving a protective tariff, and the Supreme Court issued decisions supporting a broad interpretation of the federal government's role. James Monroe and John Quincy Adams also developed foreign policies to protect American rights in the Western Hemisphere.
Overall, the Era of Good Feelings marked a period of optimism and nationalism in the United States, despite the underlying economic, social, and political concerns that would eventually give way to a new era of partisan politics.
