3. Discuss the growth of the United States in the first half of the 19th century, westward expansion, and increasing conflict over slavery:
a. Why did the application of Missouri for admission to the Union as a state instigate a crisis and how was it resolved?


b. How did economic differences create further divisions between North and South in the 1830s? Be sure to address differences over the tariff, and northern vs. southern ideas about labor.


c. After the Treaty of Guadalupe Hidalgo in 1848 adds additional territory to the United States, how did divisions over the expansion of slavery (discuss the Compromise of 1850 including the Fugitive Slave Act, Kansas-Nebraska Act, Dred Scott decision, etc. and why each was so divisive) ultimately lead to the Civil War?

d. Initial causes of the war focused on states’ rights and maintaining the Union. How and why did ending slavery become a Union war aim?
