sets the stage for an analysis of the frontier's evolution, illustrating how the westward expansion of American settlers led to a profound redefinition of identity and institutions across the nation. Turner introduces his central theme: the frontier as a dynamic meeting point between civilization and wilderness. He reflects on the discontinuation of a unified frontier line as noted in the 1890 census and contemplates the historical implications of this transformation on both American and European contexts. Throughout his introduction, Turner hints at the complex interplay between the settlers’ experiences and the evolving American ideals that emerged through continuous re-engagement with wilderness and its associated challenges.
