I) The Civil War - Parker Core Knowledge

Understanding the Context

What Was the Civil War?

The American Civil War erupted on April 12, 1861, when Confederate forces attacked Fort Sumter in South Carolina. The resulting four-year struggle claimed over 600,000 lives—more American casualties than in any other war—making it the deadliest conflict in U.S. history. The war officially ended on April 9, 1865, when General Robert E. Lee surrendered to General Ulysses S. Grant at Appomattox Court House.

At its core, the war was a clash over the future of the United States: whether the federal government could preserve the Union and end the institution of slavery, which the Southern economy and society depended on.

Major Causes of the Civil War

Understanding the Civil War requires examining its deep-rooted causes:

1. Slavery: The institution of slavery had long divided the North and South. While the North increasingly opposed slavery on moral and economic grounds, the South relied on slave labor for its agrarian economy, especially in cotton production.

2. States’ Rights vs. Federal Authority: Southern states championed states’ rights, arguing that the federal government lacked authority to interfere with state laws—especially regarding slavery. Northern leaders, however, upheld federal supremacy in maintaining national unity and enforcing constitutional rights.

Final Thoughts

3. Economic and Cultural Differences: Industrialized Northern states favored tariffs and infrastructure investment, while the agrarian South depended on exporting cotton and resisted federal economic policies. These divergent economies created regional tensions that intensified over time.

4. Political Conflicts and Secession: Tensions culminated with the election of Abraham Lincoln in 1860. Southern states viewed his anti-slavery stance as a threat and began seceding—beginning with South Carolina—leading to war.

Key Battles and Turning Points

The war unfolded across 10 major states, with dramatic shifts in momentum:

• First Battle of Bull Run (1861): The war’s first major engagement ended as a Confederate victory, dispelling Northern hopes for a swift resolution.
  
• Battle of Antietam (1862): The bloodiest single day in U.S. military history, it halted Lee’s first invasion of the North and gave Lincoln the opportunity to issue the Emancipation Proclamation.
  
• Battle of Gettysburg (1863): A decisive Union victory, marking a turning point that halted Confederate advances and shifted battlefield momentum.
  
• Siege of Vicksburg (1863): Union forces captured this key Mississippi stronghold, splitting the Confederacy in two and giving the North full control of the Mississippi River.
  
• Sherman’s March to the Sea (1864): A devastating campaign of total war led by General William Tecumseh Sherman, who destroyed infrastructure and morale in Georgia and the Carolinas.
  
• Surrender at Appomattox (1865): Lee’s surrender marked the effective end of the Confederacy and paved the way for Reconstruction.
