The Vienna Secession is an art movement, closely related to Art Nouveau, that was formed in 1897 by a group of Austrian painters, graphic artists, sculptors and architects, including Josef Hoffman, Koloman Moser, Otto Wagner and Gustav Klimt. They resigned from the Association of Austrian Artists in protest against its support for more traditional artistic styles. Their most influential architectural work was the Secession exhibitions hall designed by Joseph Maria Olbrich as a venue for expositions of the group. Their official magazine was called Ver Sacrum, which published highly stylised and influential works of graphic art. In 1905 the group itself split, when some of the most prominent members, including Klimt, Wagner, and Hoffmann, resigned in a dispute over priorities, but it continued to function, and still functions today, from its headquarters in the Secession Building. In its current form, the Secession exhibition gallery is independently led and managed by artists.

Art Nouveau is an international style of art, architecture, and applied art, especially the decorative arts. It was often inspired by natural forms such as the sinuous curves of plants and flowers. Other characteristics of Art Nouveau were a sense of dynamism and movement, often given by asymmetry or whiplash lines, and the use of modern materials, particularly iron, glass, ceramics and later concrete, to create unusual forms and larger open spaces. It was popular between 1890 and 1910 during the Belle Époque period, and was a reaction against the academicism, eclecticism and historicism of 19th century architecture and decorative art.
