Historians have debated whether or not a “Market Revolution” took place in the United States during the first half of the nineteenth century. Was the Market Revolution simply a “transportation and communication revolution,” or is there evidence that it was part of a broader process of economic and social change? Describe at least one major development or phenomenon associated with the Market Revolution (it could be an invention or innovation, political development, or evidence of social and economic change) to make your case. Lastly, how did the changes associated with the Market Revolution affect the lives of groups like urban workers, farmers, immigrants, women, and enslaved people? (Choose one group and explain fully)
