Thomas Jefferson's presidency saw debates between Democratic-Republicans and Federalists over issues like tariffs. Tariffs negatively impacted the agrarian South, while benefiting the industrial North. Key events include the Embargo Act of 1807, Marbury v. Madison establishing judicial review, and the Louisiana Purchase which doubled the size of the US, followed by the Lewis and Clark expedition.
The War of 1812, caused by British support for Native Americans and impressment, ended in a draw but fueled American nationalism. The Hartford Convention's Federalist opposition to the war led to the party's decline. Henry Clay's American System proposed protective tariffs, a national bank, and internal improvements, sparking debates between Democratic-Republicans (later Democrats) and National Republicans (later Whigs). The Missouri Compromise of 1820 addressed the balance of slave and free states, while the protective Tariff of 1828 (Tariff of Abominations) led to the Nullification Crisis, foreshadowing increasing regional tensions.
The US struggled for global recognition. Efforts included acquiring Florida from Spain (1819), the Seminole Wars, and establishing naval dominance in the Barberry Wars. Growing conflict with Native Americans and British support for them prompted President Monroe to issue the Monroe Doctrine, declaring the Western Hemisphere off-limits to European colonization. Madison's Bill #2 also restricted French and British warships from American harbors.
The Market Revolution, part of the Industrial Revolution, brought significant innovations like textile machinery, steam engines, interchangeable parts, and the telegraph. This led to increased production and economic growth. The North became industrialized, while the invention of the cotton gin solidified the South's agrarian economy reliant on slave labor. Despite economic connections, significant cultural and value differences between the North and South emerged.
The Market Revolution spurred urbanization in Northern cities due to international migration for factory work, and westward expansion created new communities along the Ohio and Mississippi rivers. This led to a more urban North and an agricultural West. While a middle class and wealthy elite grew, so did a laboring poor with long hours and low wages. Traditional gender roles shifted, with women increasingly expected to focus on domestic life.
Democracy expanded from 1800 to 1848, with property requirements for voting largely eliminated for white men (though women, Black Americans, and Indigenous people remained excluded). This ushered in participatory democracy and the Second Party System. The Dorr Rebellion in Rhode Island exemplified the push for expanded voting rights.
The 1820s and 1830s saw the rise of the Democratic Party, led by Andrew Jackson, advocating for limited federal government and the 'common man.' Jackson opposed the National Bank, vetoing its recharter and moving funds to 'pet banks.' The Whig Party, led by Henry Clay, supported a strong federal government and the American System. Jackson's policies, like the Indian Removal Act of 1830 and the subsequent Trail of Tears, sparked debates about federal power and its impact on Native Americans and the economy.
America developed a unique national identity by blending American, European, and regional influences. The Hudson River School depicted American landscapes, while writers like Washington Irving created American stories. Transcendentalism, with figures like Ralph Waldo Emerson and Henry David Thoreau, emphasized individualism and social reform (abolitionism, women's rights). Gothic literature, exemplified by Edgar Allen Poe, also gained popularity. Neoclassical architecture symbolized America's aspirations as a modern republic.
The Second Great Awakening was a religious revival driven by democratic beliefs, a response to rationalism, and the societal changes of the Market Revolution. Camp meetings and emotional revivals were common, especially on the frontier. It sparked major reform movements like abolitionism, temperance, and women's rights. African American preachers like Jarena Lee and Harry Hosier challenged traditional roles, and new religious movements like Mormonism emerged.
The Second Great Awakening fueled a wave of reform movements. Abolitionism grew in the North, with leaders like William Lloyd Garrison and Frederick Douglas advocating for immediate emancipation. The women's rights movement gained momentum, culminating in the 1848 Seneca Falls Convention, where Elizabeth Cady Stanton and Lucretia Mott issued the Declaration of Sentiments. The Temperance movement aimed to reduce alcohol consumption, and utopian communities like the Shakers and Brook Farm sought to create ideal societies.
Enslaved African Americans resisted oppression through rebellions, such as Nat Turner's (1831), which led to harsher slave laws. In the North, the free African American population grew, forming communities and institutions like the African Meeting House in Boston. The press, exemplified by Freedom's Journal, provided a platform for anti-slavery sentiments. Spiritual commitment and cultural practices, such as those at Congo Square in New Orleans, helped maintain identity and community in the face of oppression.
The South's geography fostered an economy based on cash crops like cotton, tobacco, and sugar, leading to over-cultivation and westward expansion of plantations. Despite most Southerners not owning slaves, the region's economy and leadership were built on slavery. Southern leaders like John C. Calhoun defended slavery as a 'positive good,' making it essential to the Southern way of life. This agricultural and slavery-dependent economy led to a distinct Southern identity, resistant to change and heavily reliant on foreign trade, creating tension with the industrialized North that would ultimately lead to conflict.
