Social Studies: AP US History: The Civil War Era 1848-1877 Worksheet

Question 1

Explain one way the Mexican-American War intensified sectional conflict in the United States between 1848 and 1850.

Accepted Answer

The Mexican-American War intensified sectional conflict because the United States gained large western territories, and Americans argued over whether slavery would be allowed there. Debates over the Wilmot Proviso and the Compromise of 1850 showed that territorial expansion made slavery a national political crisis.

Question 2

Compare the Missouri Compromise of 1820 with the Kansas-Nebraska Act of 1854. How did the Kansas-Nebraska Act change the earlier approach to slavery in the territories?

Accepted Answer

The Missouri Compromise tried to limit slavery's expansion by drawing a geographic line across the Louisiana Purchase. The Kansas-Nebraska Act changed that approach by allowing settlers to use popular sovereignty to decide the slavery question, which effectively repealed the Missouri Compromise line and increased sectional violence in Kansas.

Question 3

Identify and explain one effect of the Dred Scott v. Sandford decision on national politics.

Accepted Answer

The Dred Scott decision deepened sectional tensions because the Supreme Court ruled that Congress could not ban slavery in the territories. This strengthened proslavery claims, angered many Northerners, and helped convince some Americans that the Slave Power controlled the federal government.

Question 4

Explain why the formation of the Republican Party in the 1850s was significant.

Accepted Answer

The formation of the Republican Party was significant because it created a major political party dedicated to stopping the expansion of slavery into the western territories. Its rise showed the collapse of the Second Party System and the growth of politics organized around sectional interests.

Question 5

Use the election of 1860 to explain why several Southern states seceded from the Union.

Accepted Answer

Several Southern states seceded after the election of 1860 because Abraham Lincoln won the presidency without carrying any Deep South states and represented a party opposed to slavery's expansion. Many white Southerners believed his election threatened the future of slavery and their political power.

Question 6

Describe two major advantages the Union had at the beginning of the Civil War and explain how one advantage helped the Union war effort.

Accepted Answer

The Union had a larger population and greater industrial capacity than the Confederacy. Its industrial strength helped the Union produce more weapons, railroad supplies, ships, and other materials needed for a long war.

Question 7

Explain how the Emancipation Proclamation changed the meaning or goals of the Civil War.

Accepted Answer

The Emancipation Proclamation changed the war by making the destruction of slavery an official Union goal in Confederate-controlled areas. It also allowed African American men to enlist in the Union Army and made it harder for Britain or France to support the Confederacy.

Question 8

Analyze the importance of African American soldiers in the Union war effort.

Accepted Answer

African American soldiers were important because nearly 180,000 served in the Union Army and helped fill the need for troops. Their service strengthened the Union war effort and supported the argument that African Americans deserved freedom and citizenship rights.

Question 9

Explain one reason the Battle of Gettysburg or the fall of Vicksburg was a turning point in the Civil War.

Accepted Answer

The fall of Vicksburg was a turning point because it gave the Union control of the Mississippi River and split the Confederacy in two. This weakened Confederate transportation and supported the Union strategy of dividing and defeating the South.

Question 10

Explain how wartime policies expanded the power of the federal government during the Civil War.

Accepted Answer

Wartime policies expanded federal power through actions such as conscription, the suspension of habeas corpus, the creation of a national banking system, and federal support for railroads and higher education. These policies showed that the national government could mobilize people, money, and resources on a much larger scale than before.

Question 11

Identify the purpose of the 13th, 14th, and 15th Amendments. Briefly explain how they changed the Constitution.

Accepted Answer

The 13th Amendment abolished slavery, the 14th Amendment defined national citizenship and promised equal protection of the laws, and the 15th Amendment prohibited denying voting rights based on race, color, or previous condition of servitude. Together, they expanded federal protection of civil rights and changed the relationship between states and the national government.

Question 12

Compare Presidential Reconstruction with Radical Republican Reconstruction.

Accepted Answer

Presidential Reconstruction, led by Lincoln and Johnson, generally favored a quicker and more lenient return of Southern states to the Union. Radical Republican Reconstruction required stronger federal action, including military districts, protection for freedpeople, and new state constitutions that recognized Black male suffrage.

Question 13

Explain one goal of the Freedmen's Bureau and evaluate one challenge it faced.

Accepted Answer

One goal of the Freedmen's Bureau was to help formerly enslaved people by providing education, labor contracts, legal assistance, and basic relief. It faced challenges from limited funding, Southern white resistance, and political opposition from President Andrew Johnson and others.

Question 14

Explain how Black Codes and sharecropping limited the freedom of African Americans after the Civil War.

Accepted Answer

Black Codes limited African American freedom by restricting movement, labor choices, and civil rights in the South. Sharecropping often trapped freedpeople in debt because they rented land and supplies from landowners and had to repay them with a portion of the crop.

Question 15

Evaluate the extent to which Reconstruction was a success by 1877. Write a defensible thesis statement using at least one specific piece of evidence.

Accepted Answer

A defensible thesis could state that Reconstruction was only partly successful because the 13th, 14th, and 15th Amendments permanently changed the Constitution, but white Southern resistance, the rise of groups such as the Ku Klux Klan, and the Compromise of 1877 undermined many of the gains made by freedpeople.
