Historical Research Capabilities
With its wealth of primary sources, this collection is an unequalled resource for researching the Haymarket affair. The Special Presentations of the Chicago Historical Society's website also provide invaluable help in such study. In addition, the collection is an excellent resource for researching the development of radicalism in the labor movement and the bitter conflicts between management and labor in the 1880s.
The collection may also inspire research into topics that are not thoroughly covered in this collection but figure prominently in the history of the labor movement. For example, the collection provides the preamble and declaration of principles of the Knights of Labor of America, one of the earliest workers' unions. Research the union and its role in promoting the eight-hour workday. Examine the goals of the Knights of Labor and explain the impact of violence at Haymarket Square on the union.
Users of the collection may also want to research the role of the Pinkerton Agency in suppressing strikes in the United States during the post-Civil War era.
- What role did the Pinkerton Agency play in suppressing strikes in Chicago prior to Haymarket?
- What was organized labor's reaction to the "Pinkertons"?
