Major Effects of the Missouri Compromise of 1820 - In this activity, students will use a spider graph to branch out other acts, compromises and court cases that ultimately resulted from the Missouri Compromise of 1820. This will allow students to centralize the compromise, and what long and short term effects it had on the nation and question of slavery. Students will be able to connect and explain how the compromise influenced future legislation and debate over slavery. Topics that are useful include the Kansas-Nebraska Act of 1854, The Compromise of 1850, the Dred Scott decision, and the eventual Civil War. Other ideas include the Wilmot Proviso and Lincoln-Douglas debates. Teachers, however, can pre-select any topics (including thematic ideas like the history of slavery, its extension, popular sovereignty, causes of civil war, etc.) to branch off of the Missouri Compromise.
