Which Austrian movement was part of Art Nouveau?

The Austrian movement that was part of Art Nouveau was the Vienna Secession.

Founded in Vienna in 1897, the Vienna Secession brought together artists, architects, designers, and sculptors who wanted to break with the conservative Vienna Künstlerhaus and its historicist traditions. Gustav Klimt was its first president, while Josef Hoffmann, Koloman Moser, Joseph Maria Olbrich, and Otto Wagner were among its important members.

The movement promoted a unified “total work of art,” joining painting, architecture, furniture, graphic design, and decorative arts. Olbrich’s Secession Building, completed in 1898, became its architectural emblem, while the journal Ver Sacrum publicized its ideas. Its style often used geometric patterns and controlled ornament alongside Art Nouveau’s organic inspiration.

A common mix-up is treating the Vienna Secession as identical to all Art Nouveau. It was an Austrian regional interpretation of the wider movement, sometimes called Secessionstil. Constructivism, De Stijl, and Bauhaus developed later and are associated with different modernist directions.
