The so-called "Glasgow" style is exhibited in Europe and influences the Viennese Art Nouveau movement known as Sezessionstil (in English, the Vienna Secession) around 1900.

Charles Rennie Mackintosh and Margaret Macdonald Mackintosh exhibit to great acclaim at the Eighth Secession Exhibition in Vienna, as does Charles Robert Ashbee.

Mackintosh, his future wife Margaret MacDonald, her sister Frances MacDonald, and Herbert MacNair had met at evening classes at the Glasgow School of Art and become known as a collaborative group, "The Four", or "The Glasgow Four", and are prominent members of the "Glasgow School" movement.

The group exhibits in Glasgow, London and Vienna, and these exhibitions help establish Mackintosh's reputation.

Mackintosh also works in interior design, furniture, textiles and metalwork.

Much of this work combines Mackintosh's own designs with those of his wife, whose flowing, floral style complements his more formal, rectilinear work. 

Margaret, exhibiting with Mackintosh, is an influence on the Secessionists Gustav Klimt and Josef Hoffmann.
