In this lesson, students analyze primary and secondary source documents in an effort to answer the central historical question: What caused the Chicago race riots of 1919? The teacher begins with a mini-lecture on the Great Migration and then streams the video trailer for a documentary film called Up South. Students then read 2 secondary source accounts of the riots: 1 from a generic textbook and another from John H. Franklin’s From Slavery to Freedom. Students analyze with a graphic organizer and discuss: which account is more believable and why? They then do the same for 3 primary sources, drawn from contemporary newspapers and magazines. A final class discussion attempts to identify the real cause of the riots and places them in a larger context of racial violence at the time.
