Although generally called a movement, it is more valid to see modernism as an international body of literature characterized by a new self-consciousness about modernity and by radical formal experimentation. Several literary movements and styles, notably Imagism and Vorticism, were fostered within modernism, which flourished from around 1890 until 1940.
