By moving away from ornamentation and instead focusing on function in design, Bauhaus ushered in modernist design.
After leading Bauhaus artists fled Nazi Germany, they spread their clean, geometric designs around the world. Leading Bauhaus architects later designed the Seagram Building in New York in 1957.
This spurred the creation of similar skyscrapers in American cities, which created a demand for Bauhaus-influenced furniture to fill them. Bauhaus designs were soon being mass-produced, and this has a ripple-effect on 20th century furniture design. IKEA is a notable example.
The mid-century modern design movement from the 40s to the 70s was clearly influenced by the functional, geometric, unadorned aesthetic of Bauhaus.
