Progressivism emerged in the late 19th century as a response to rapid industrialization and urbanization in the United States. Reformers came from all classes and regions and sought to address issues like political corruption, unsanitary living conditions in cities, and lack of protections for workers and consumers. Settlement houses like Jane Addams' Hull House aimed to improve life for immigrants through social services, education, and investigations into public health issues. Progressive reforms sought to give government a greater role in regulating industry and ensuring social welfare and justice.
