1. Westward Expansion and Manifest Destiny

Background:

• Manifest Destiny was the belief that the United States was destined to expand across the North American continent, spreading democracy and civilization. This ideology fueled the country's territorial ambitions during the mid-19th century.

Key Events in Westward Expansion:

• Annexation of Texas (1845): The U.S. annexed Texas, which had gained independence from Mexico in 1836. This led to the Mexican-American War.

• Mexican-American War (1846–1848): Following the annexation of Texas, the U.S. fought Mexico over territorial disputes, resulting in the U.S. acquiring vast territories, including California, Nevada, and parts of several other western states under the Treaty of Guadalupe Hidalgo.

• Oregon Trail and Oregon Territory: The U.S. and Britain reached a peaceful agreement over the Oregon Territory, which was divided at the 49th parallel, allowing for further American settlement in the West.

• The California Gold Rush (1848–1855): The discovery of gold in California led to a massive migration westward, dramatically increasing California's population and economy.

Key Issues to Revise:

• The significance of Manifest Destiny in motivating westward expansion.

• The causes and outcomes of the Mexican-American War and the territorial gains for the U.S.

• The impact of the Oregon Trail and the California Gold Rush on the settlement of the West.

2. The Impact of Slavery on the American Economy

Background:

• The debate over the expansion of slavery into newly acquired territories was a major political issue during this period. While the North became more industrialized, the South remained largely agricultural and dependent on slavery.

Key Events and Issues:

• Compromise of 1850: A series of laws passed to address the territorial and slavery issues raised by the Mexican-American War. It included the Fugitive Slave Act, which required that runaway slaves be returned to their owners, and the admission of California as a free state.

• Kansas-Nebraska Act (1854): This act allowed the residents of Kansas and Nebraska to decide for themselves whether to allow slavery, leading to violent conflicts known as "Bleeding Kansas."

• Dred Scott Decision (1857): The U.S. Supreme Court ruled that African Americans, free or enslaved, could not be citizens and that Congress had no authority to regulate slavery in the territories.

Key Issues to Revise:

• The economic role of slavery in the Southern economy.

• The political debates surrounding the Compromise of 1850 and the Kansas-Nebraska Act.

• The implications of the Dred Scott Decision for the status of slavery and African Americans in the U.S.

3. Political Developments and the Divisions Between North and South

Background:

• The growing divisions between the North and South were fueled by differences over slavery, economics, and political power. The question of how to address slavery in the territories, combined with rising sectionalism, led to a deepening national crisis.

Key Political Developments:

• The Rise of Abolitionism: Abolitionists like Frederick Douglass, Harriet Beecher Stowe (author of Uncle Tom's Cabin), and William Lloyd Garrison played pivotal roles in raising awareness about the horrors of slavery and advocating for its abolition.

• The Republican Party: The Republican Party was formed in the 1850s in response to the Kansas-Nebraska Act, positioning itself as an anti-slavery party. Abraham Lincoln, elected in 1860, was the first Republican president.

• The Election of 1860: Abraham Lincoln’s election was the final straw for many Southern states, leading them to secede from the Union, starting with South Carolina.

Key Issues to Revise:

• The role of abolitionism in heightening tensions between the North and South.

• The impact of Abraham Lincoln’s election on sectionalism and the secession of Southern states.

• The development of the Republican Party and its role in the political divisions of the period.

4. The Civil War and Reconstruction

Background:

• The Civil War (1861–1865) was the culmination of decades of sectionalism, political conflict, and economic disparity between the North and South, with the issue of slavery at its heart.

Key Events in the Civil War:

• The Battle of Fort Sumter (1861): The war began when Confederate forces attacked a U.S. military garrison in South Carolina.

• The Emancipation Proclamation (1863): Issued by President Lincoln, this declared the freedom of all slaves in Confederate-held territory.

• Major Battles: Key battles such as Gettysburg and Antietam marked the turning points in the war, with the Union army gaining the upper hand.

• The Surrender at Appomattox (1865): Confederate General Robert E. Lee surrendered to Union General Ulysses S. Grant, effectively ending the war.

Reconstruction:

• After the war, the U.S. faced the challenge of reintegrating the Southern states and rebuilding the South's economy. Reconstruction policies, including the 13th, 14th, and 15th Amendments, sought to grant civil rights to freed slaves and rebuild the South, but resistance from white Southerners led to the rise of Jim Crow laws.

Key Issues to Revise:

• The causes and key events of the Civil War, including battles, leadership, and major turning points.

• The aims and successes/failures of Reconstruction, especially the amendments and the challenges of reintegration.

5. The Rise of Industrialization

Background:

• Following the Civil War, the U.S. rapidly industrialized, particularly in the North. This period saw the growth of factories, railroads, and the rise of powerful industrialists.

Key Developments:

• The Transcontinental Railroad: Completed in 1869, it linked the East and West coasts, facilitating trade, migration, and economic growth.

• The Growth of Big Business: Figures such as Andrew Carnegie (steel), John D. Rockefeller (oil), and J.P. Morgan (banking) became emblematic of the rapid industrialization of the U.S.

• Labor Movements: The rise of industrialization led to the growth of labor unions, such as the American Federation of Labor, which fought for workers’ rights and better conditions.

Key Issues to Revise:

• The economic, social, and political impact of industrialization on the U.S.

• The role of the Transcontinental Railroad in facilitating economic growth.
