What was the name of the american literary movement in the early 1900s that sought to remove all unnecessary, flowery words and let a poem's rhythm flow from the phrasing, rather than manipulating the phrasing to fit a meter?

Imagism

Ezra Pound (1885-1972) is often noted as the founding figure in the Imagist movement in poetry.  Imagists were reacting against the floweriness of Romantic and Victorian poetry styles, and wanted a direct style instead. They also experimented with free verse rather than being bound to a particular metric pattern.  Some other names associated with the Imagist movement were Amy Lowell and Richard Aldington.
