In Russia, the movement revolved around the art magazine Mir iskusstva ('World of Art'), which spawned the revolutionary Ballets Russes.
The Polish movement was centred in Krakow and was part of the Mloda Polska movement. Stanisław Wyspiański was the leading Art Nouveau artist in Poland; his paintings, theatrical designs, stained glass, and building interiors are widely admired and celebrated in the National Museum in Kraków. Art Nouveau buildings survive in most Polish cities (Łódź, Kraków), with the exception of Warsaw, where Communist authorities destroyed the few examples that survived the Nazi razing of the city on the grounds that the buildings were decadent.
The Slovene Lands were another area influenced by Art Nouveau. At its beginning, Slovenian Art Nouveau was strongly influenced by the Viennese Secession, but it later developed an individual style. Important architects in this style include Max Fabiani, Ciril Metod Koch, Jože Plečnik, Ivan Vurnik and a Croatian Josip Vancaš, with the vast majority of the architecture to be found in Ljubljana.
Croatia was an area of secessionist architecture as well. Architects like Vjekoslav Bastl and Baranyai developed a mixture between modernism and classical Art Nouveau
