Worked example: explain two ways different

Explain two ways in which the position of enslaved people in 1850 was different from their position in 1870. (6 marks)

1. Legal status: in 1850 slavery was legal in the South and protected by the Fugitive Slave Act; by 1870 the 13th Amendment had abolished it.
2. Rights: in 1850 black people had no citizenship (confirmed by Dred Scott in 1857); by 1870 the 14th and 15th Amendments gave citizenship and banned racial discrimination in voting.

Essay plan in outline

“Westward expansion was the main cause of conflict between North and South in the years 1803–61.” How far do you agree?

• For: each new territory reopened the slavery question — Missouri (1820), the Mexican lands and the Compromise of 1850, Kansas–Nebraska (1854) and Bleeding Kansas.
• Against: slavery itself and the moral campaign against it; states’ rights; economic differences between the industrial North and the cotton South; Dred Scott and John Brown; Lincoln’s election.
• Judgement: expansion was the arena in which the slavery conflict was fought; slavery was the issue.

Common mistakes and exam traps

• Narrating instead of tracing change. The (c) question covers at least 25 years; show change and continuity.
• Confusing the compromises. 1787 (Connecticut), 1820 (Missouri), 1850.
• Treating emancipation as complete equality. Black Codes and later violence limited freedom.
• Leaving out Native Americans. They appear in topics 2 and 5.
• Inventing numbers. Use approximate figures only when certain.

Frequently asked questions

Why was the Missouri Compromise important? It balanced slave and free states and drew a line that kept the peace until 1854.

What made 1863 a turning point? Gettysburg, Vicksburg and the Emancipation Proclamation.

Why did Reconstruction end in 1877? Northern commitment faded, white Southern resistance grew, and federal troops were withdrawn.
