 The late 19th century, known as the "Belle Époque", with its "Fin de siècle" retrospectively appeared as a "golden age" of European culture, cut short by the outbreak of World War I in 1914.The main periods of 20th century literature are captured in the bipartite division, Modernist literature and Postmodern literature, flowering from roughly 1900 to 1940 and 1945 to 1980 respectively, divided, as a rule of thumb, by World War II.Popular literature develops its own genres such as fantasy and science fiction.
