Which event is associated with the rise of the Progressive movement?

The rise of the Progressive movement is fundamentally linked to the societal and economic changes brought about during the Gilded Age, a period characterized by significant industrial growth and rampant economic inequality in the United States. This era highlighted the stark contrasts between wealth and poverty, along with the exploitation of workers, the rise of monopolies, and the corruption in politics and business.

The Progressive movement emerged as a response to these issues, aiming to address the social, political, and economic injustices that had become entrenched. Reformers sought to improve living conditions, expand democracy, regulate big businesses, and promote social welfare. The problems associated with the rapid industrialization and urbanization of the Gilded Age—such as poor labor conditions, corruption in government, and inadequate public services—stimulated a call for change, ultimately leading to the establishment of the Progressive movement to seek reform and create a more equitable society.

In contrast, the other options represent different historical contexts that either preceded or followed the Progressive Era and did not serve as direct catalysts for its onset. The Industrial Revolution set the stage for changes in production and society but was too broad and widespread globally to be identified specifically with the Progressive movement. World War I occurred after the movement was in full swing
