Working claim: The period from 1784 to 1865 was a time of both expansion and division in the United States.
A. Expansion
1. Westward movement
a. After winning their independence from Britain in the Revolutionary War, Americans gradually expanded their nation to the West.
b. Indeed, newspaper editor John O'Sullivan famously proclaimed in 1845 that the land to the West of the original colonies belonged to the United States "by right of our manifest destiny to overspread and to possess the whole of the continent which Providence has given us for the development of the great experiment of liberty and federatative self-government entrusted to us."
c. The reality was not as attractive as this idealistic sentiment.
i. While the Mormons who migrated to modern-day Utah in the 1840s certainly sought liberty, most of the other people who settled the West were motivated by material concerns.
(a) The pioneers who traveled on the Oregon Trail in the 1830s and 1840s sought land where they could earn a decent living.
(b). Some heading west during the 1849 California Gold Rush hoped to get rich.
ii. The process of settling--or, in some cases, exploiting--this land involved many unsavory consequences, including conflicts with Native Americans, destruction of buffalo, and mistreatment of Chinese immigrants.
B. Division
1. While America was expanding west, it also was dividing between north and south.
a. In the northern United States, where the economy was largely industrial, many Americans opposed slavery and tried to restrict its spread or even outlaw it entirely.
b. The southern states, on the other hand, had a primarily agricultural economy and depended heavily on slave labor.
2. Despite attempts at compromise, such as the Missouri Compromise of 1820 and the Compromise of 1850, 11 southern states eventually seceded from the Union and formed the Confederate States of America.
3. The American Civil War lasted from 1861 to 1865.
i. The Confederate Army of the south sought independence.
ii. The north's Union Army sought to preserve the Union.
iii. The war ended when Confederate General Robert E. Lee surrendered to Union General Ulysses S. Grant at Appomattox Courthouse in Virginia.
The American culture of this period showed the same hunger, confidence, and sense of adventure that characterized the westward migration. While western pioneers were exploring and settling the land, other Americans broke ground in the scientific, social, and artistic realms.
A. Science
1. Eli Whitney invented the cotton gin in 1793.
2. Samuel B. Morse invented the telegraph in 1844.
3. Elias Howe inventedthe "sewing jenny" in 1846.
B. Transportation
1. The Baltimore and Ohio Railroad became the first to operate in America in 1830.
2. The Transcontinental Railroad was completed in 1869.
3. Between these two dates, American laborers laid more than 30,000 miles of track.
C. Society
1. Horace Mann and Catharine Beecher reformed education.
2. Dorothea Dix reformed prisons.
3. Lucretia Mott was a women's advocate.
4. Frederick Douglass, John Brown, and William Lloyd Garrison were abolitionists.
5. This was also the age of temperance societies.
6. Utopian communities included New Harmony and Brook Farm.
7. Literate Americans could choose from numerous magazines and newspapers, including 47 newspapers in New York alone in 1830.
8. New Yorkers packed a free gallery operated by the American Art-Union, an association of artists and patrons who sought to promote American art, and the world saw the emergence of several important American artists, including Albert Bierstadt, Thomas Cole, and Hiram Powers.
