The Progressive Era started out of concerns from the middle class about problems that afflicted society, workers, etc. Many point to the Triangle Shirtwaist fire as a catalyst for the Progressive movement, but also the concerns of the Grange Movement and Farmer's Alliances are catalysts. The movement was led by middle class Protestant whites. Also, the Progressive movement was helped by "muckrakers," like Upton Sinclair who exposed the horribleness of the meat-packing industry. Anyway, a number of reforms were passed, such as the 16th, 17th, and 18th amendments and the Pure Food and Drug Act. At the same time though, there was a nativist and racist tinge to the Progressive movement, such as the Mann Act and prohibition. Key figures were Robert La Follette, Theodore Roosevelt, and Jane Addams.
