The document provides an overview of the development of modernist architecture in the early 20th century. It discusses key intellectual developments like Einstein's theory of relativity that challenged traditional notions. Artistic movements like De Stijl and the Bauhaus emerged, advocating simplicity and abstraction through use of basic geometric forms and primary colors. The Bauhaus school under Gropius and later Mies van der Rohe promoted integrating art and craft, and understanding new technologies. Mies van der Rohe's motto of "Less is More" epitomized the International Style. Gerrit Rietveld's Schroder House exemplified De Stijl principles through its rigid planes and use of color.
