"The Frontier in American History" examines the importance of the unsettled, western frontier in shaping the political, economic, and social identity of the United States. The book argues that the constant westward expansion and the challenges it presented played a crucial role in developing American democracy, individualism, and innovative spirit. The author further posits that the closing of this frontier at the end of the 19th century marked a significant shift in American society, which now had to find new ways of growth and innovation.
