What This Standard Means
What Students Need to Do
- Read passages from Southern states’ secession declarations and find the reasons their leaders gave for leaving the Union. Use those passages to explain why slavery was the central cause.
What Mastery Looks Like
- A student can point to language about slavery in more than one declaration. They can explain why a general claim about states’ rights does not tell the whole story without naming the right those leaders sought to protect.
Common Misconceptions
- Students may name tariffs as the main cause even when the passages focus on slavery. They may treat states’ rights as a separate cause without asking which right the states wanted to defend.
How to Assess It
- Give students Mississippi’s line, “Our position is thoroughly identified with the institution of slavery.” Ask: What reason for secession does this line reveal, and which words support your answer?

Ways to Teach It
Give pairs printed excerpts from Mississippi and South Carolina’s declarations; have them highlight references to slavery and circle each state’s stated reason for secession.
Ask, “What did these state leaders say they wanted to protect?” Have students answer using one line from each declaration.
Give pairs claim cards reading “protect slavery,” “oppose tariffs,” and “defend state power”; have them sort the claims by direct evidence in Mississippi’s declaration.
Bring a printed school closure notice and have students mark its stated reasons, then compare how that notice and a secession declaration explain a decision.
