It develops a model of a prairie-middle-class based on the material and documentary datasets at New Philadelphia, Illinois. These two datasets comprise a single historic-archaeological record that was created by people living in this town during the middle decades of the 19th century. New Philadelphia was a founder town, established by “Free” Frank McWorter, an African American, who was born into slavery but who purchased his freedom, along with 13 family members. Chapter 1 presents the research question: What is the material expression of the emergent middle on the 19th-century American prairie? Chapter 2 outlines the historical developments necessary for the emergence of the middle class on the American prairie during the 19th century. Chapter 3 presents the theoretical context for examining the historical archaeological record at New Philadelphia. Chapter 4 presents the methodology of historical materialism to explain social change through processes of change. A model for the expansion of the capitalist mode of production is stated. This model forms the basis for four hypotheses about the broad cultural experience with capitalist expansion. Each hypotheses leads to specific sub-hypotheses about the personal experiences at New Philadelphia. These sub-hypotheses are bridging arguments to connect the local manifestation to the wider process of capitalist expansion. Chapter 5 presents conclusions and suggestions for future work. Show less
