The Bauhaus was founded in 1919 in the city of Weimar by German architect Walter Gropius (1883–1969). Its core objective was a radical concept: to reimagine the material world to reflect the unity of all the arts. Gropius explained this vision for a union of art and design in the Proclamation of the Bauhaus (1919), which described a utopian craft guild combining architecture, sculpture, and painting into a single creative expression. Gropius developed a craft-based curriculum that would turn out artisans and designers capable of creating useful and beautiful objects appropriate to this new system of living.
