What architectural style emphasizes modern design and emerged after World War I?

The International Style is recognized for its emphasis on modern design principles that emerged prominently after World War I. This architectural style is characterized by clean lines, functional forms, and an absence of ornamentation, reflecting a break from traditional architectural elements. The focus is on volume over mass; the designs often utilize glass, steel, and reinforced concrete to create open, flexible spaces that are devoid of historical references.

Originating in the 1920s and 1930s, the International Style also emphasizes the idea of creating structures that are suitable for modern life, allowing for a seamless connection between interior and exterior environments, which was revolutionary at the time. This approach greatly influenced not only architecture but also urban planning and design philosophy throughout the 20th century and beyond.

In contrast, the other architectural styles mentioned represent different historical contexts and design philosophies. The Prairie School, for example, is rooted in an earlier tradition, emphasizing harmony with the landscape, while Postmodernism emerged much later, reacting against the principles of modernism. Neoclassicism is characterized by its revival of classical architecture, focusing on grandeur and symmetry, which is fundamentally opposed to the minimalistic ideals of the International Style.
