{{main|20th-century art}}
* The art world experienced the development of new styles and explorations such as [[fauvism]], [[expressionism]], [[Dadaism]], [[cubism]], [[de stijl]], [[surrealism]], [[abstract expressionism]], [[color field]], [[pop art]], [[minimal art]], [[lyrical abstraction]], and [[conceptual art]].
* The [[modern art]] movement revolutionized art and culture and set the stage for both [[Modernism]] and its counterpart [[postmodern art]] as well as other [[contemporary art]] practices.
* [[Art Nouveau]] began as a form of architecture and design but fell out of fashion after World War I. The style was dynamic and inventive but unsuited to the depression of the Great War.
* In Europe, [[modern architecture]] departed from the decorated styles of the [[Victorian era]]. Streamlined forms inspired by machines became commonplace, enabled by developments in [[building materials]] and technologies. Before World War II, many European architects moved to the United States, where modern architecture continued to develop.
* The automobile increased the mobility of people in the Western countries in the early-to-mid-century, and in many other places by the end of the 20th century. [[Urban planning|City design]] throughout most of the West became focused on transport via car.
