Under whose administration did the "Era of Good Feelings" occur?

The "Era of Good Feelings" occurred during James Monroe's presidency, which lasted from 1817 to 1825. This period is characterized by a sense of national unity and a decline in partisan political strife following the War of 1812. The term reflects the relative peace and stability that prevailed at the time, primarily due to the absence of major political opposition. Monroe's administration is notable for its focus on national expansion and the promotion of American nationalism, including the Monroe Doctrine, which asserted U.S. influence in the Western Hemisphere.

During this era, the Federalist Party had significantly weakened, leading to a dominant Democratic-Republican Party and a sense of collaboration across political lines. This atmosphere contributed to various social and economic developments, such as the growth of infrastructure and westward expansion.
