What does Ken Burns’s The Civil War say about the causes?
PBS describes Ken Burns’s nine-episode series, first aired in September 1990, as covering slavery, the Union and states’ rights, John Brown’s raid, Lincoln’s election, and Fort Sumter. Burns’s summary says, “What began as a bitter dispute over Union and States’ Rights, ended as a struggle over the meaning of freedom in America.” PBS’s series page also reports that 40 million people watched its September 1990 premiere; that is a historical audience figure, not a current viewership measure.
So a fair criticism is about clarity and emphasis, not that the series leaves slavery out. Its broad framing can make the causal hierarchy less explicit than some viewers want: slavery was not merely one item in an equal list of disputes. It was central to why the seceding states left the Union.
What started the Civil War?
Decades of conflict over slavery and power
For decades, Americans fought over slavery’s place in the Union, whether it could expand, and how political power would be distributed between free and slave states. The National Park Service describes slavery as the most important issue within wider disputes over federal authority, economics, and cultural values. The NPS overview of the causes explains that these conflicts accumulated over time; the war did not begin from a single sudden disagreement.
#1 Best Overall
The secession crisis
Lincoln’s election and fears about the future of slavery intensified the crisis. The seceding Deep South states acted primarily out of concern for slavery’s future, and they anticipated that an independent Confederacy could expand slaveholding power. The NPS account places those political calculations within the wider conflict over slavery and federal authority.
The attack on Fort Sumter
After states seceded, Confederate forces attacked the Union-held Fort Sumter in Charleston Harbor on April 12, 1861. The National Park Service identifies the attack as the event that precipitated the war. It was the immediate outbreak of fighting, not the underlying cause of secession. The NPS account of Fort Sumter describes the attack and its place in the conflict.

Was the war about slavery or states’ rights?
State sovereignty was part of the argument, but it needs an object: what rights were being asserted, and for what purpose? South Carolina’s secession declaration directly tied its claims to slavery. It objected that non-slaveholding states had “denounced as sinful the institution of slavery” and “encouraged and assisted thousands of our slaves to leave their homes.” The National Park Service quotes the declaration in its account of South Carolina’s secession.
That document is evidence of what South Carolina’s secessionists said they were defending. It does not mean every person had identical motives, or that constitutional and political disputes did not matter. It does mean that describing the cause simply as an abstract conflict over states’ rights obscures the institution those claims were meant to protect.
How to judge an explanation of the war’s causes
- Does it identify slavery as central to secession? It should not present slavery as an incidental factor alongside supposedly equal causes.
- Does it explain what “states’ rights” meant in context? Contemporary secession documents help connect sovereignty claims to slavery and resistance to antislavery action.
- Does it separate long-term causes from the first fighting? The decades-long conflict and secession crisis explain how the country reached war; Fort Sumter marks the immediate outbreak.
- Does it use contemporary documents? Secession declarations show what secessionists publicly argued at the time, alongside later historical interpretation.
Why the distinction matters
A concise account can hold both scale and sequence in view: slavery was central to secession; conflicts over its expansion and political power drove the crisis; and Confederate forces opened hostilities at Fort Sumter. That gives viewers a clearer causal explanation without pretending that every political dispute or individual motive was identical.
