The modernist movement in 20th century architecture marked a radical shift compared to previous styles. The forms of the past were rejected and architecture sought to distance itself from earlier traditions. The industrial and social revolution generated a variety of building typologies, such as housing, museums and theatres, which reflected the economic values of capitalist society.
The use of iron and glass in construction became commonplace, both in industrial and public buildings, incorporating undulating features and natural vegetation motifs. Modernism in architecture, represented by prominent architects such as Victor Horta, Hector Guimard and Antoni Gaudí, sought to break with traditional forms and create an architectural language unique to the 20th century.
It drew inspiration from craftsmanship, nature and technology, standing out for its use of new materials, innovation, functionality and the fusion of the arts in modernist buildings. On the other hand, the modern movement, led by Le Corbusier, Walter Gropius and Mies van der Rohe, was characterised by its focus on functionality and the elimination of unnecessary ornamentation.
