Modernist architecture emerged in the early 20th century, emphasizing simplicity, functionality, and the use of new materials like steel and glass. It sought to break away from traditional styles, focusing on clean lines and open spaces. Key figures in this movement include Le Corbusier and Ludwig Mies van der Rohe, who championed the idea that form should follow function. This architectural style often features flat roofs, large windows, and minimal ornamentation. Notable examples include the Villa Savoye in France and the Seagram Building in New York City. Modernist architecture reflects a belief in progress and the potential of design to improve everyday life.
