Art Nouveau was an artistic style popular from 1890-1910 that featured organic, flowing, and curving forms inspired by nature. It aimed to modernize design and move away from historical eclectic styles. Key ideas included establishing modernism, responding to a belief in natural forms, and considering architecture, graphics, interior design, jewelry, furniture and more as a "total" art style. In Catalonia, Modernisme had similar characteristics and represented Catalan identity and independence, led by architects like Antoni Gaudí, Lluís Domènech i Montaner, and Josep Puig i Cadafalch.
