Presidents James Monroe, John Quincy Adams, and Andrew Jackson presided over a pivotal era in American history, known as the Era of Good Feelings and the Age of Jackson. Monroe's "Monroe Doctrine" asserted America's influence in the Americas, while Adams focused on internal improvements and economic development. Jackson's populist presidency expanded voting rights, challenged the power of the wealthy, and aligned with the common man, sparking the Democratic Party's rise to prominence. These three presidents shaped the nation's political landscape, territorial expansion, and economic policies, laying the foundation for America's future growth and westward expansion.
