Question

the period 1800–1865 is considered a time when american literature "found its voice." what incited this literary movement?

Answer 1

That was a time period when American writers started writing about American people and creating stories based on their culture and history. Elements from European history were slowly removed and instead we got things about the American way of life from writers such as Walt Whitman, Thoreau, Melville, Mark Twain, and many others.
