What was tureners view of the role of the American frontier in 1893?

In 1893, historian Frederick Jackson Turner presented his frontier thesis, arguing that the American frontier was crucial in shaping the nation's character and democracy. He believed that the continuous westward expansion fostered individualism, innovation, and a spirit of independence, which were foundational to American identity. Turner asserted that the closing of the frontier marked the end of a significant era in American history, suggesting that it would lead to new challenges for the nation as it sought to define itself without the expansive wilderness.
